25 interesting facts that make men and women different

Men are not from Mars, and women are not from Venus. They are all from the same species on the same planet. But the sexes are definitely not exactly the same, the differences between men and women do exist and are important.

These differences are mainly manifested in biological functions, and can help you better understand your health needs. These differences give both sexes unique advantages and help you achieve your most important task-survival.

But let’s talk about the similarities first, and then return to what makes men and women different.

There are two things you may not know: genetically, 98.5% of the DNA of men and women are identical, and they even have the same hormones. But the ratio of these hormones explains some of the differences between men and women.

Let’s first dive into these 25 interesting facts and explore the important physiological, biological, and nutritional differences between men and women.

  1. Men usually have thicker skin, about 25% thicker than women, and have a higher density of collagen.
  2. The difference in density is not limited to the skin; generally, men have denser and stronger bones, tendons, and ligaments than women.
  3. From the age of 14 to 51, women usually need more iron than men. This is because women lose blood during menstruation, which usually lasts from 28 to 40 days.
  4. On average, men’s muscle mass is usually higher than women’s, and their skeletal muscles move faster and more powerfully. But women’s muscles are better able to resist fatigue and recover faster.
  5. For most women, the second longest finger is the index finger next to the thumb. Men are the opposite. Their ring finger (the one next to the little finger) is usually longer than their index finger.
  6. Folic acid is an essential vitamin, men and women need it. But folic acid is particularly important for women of childbearing age. During pregnancy, women need enough folic acid to support the baby’s neurodevelopment.
  7. Male and female brains differ in structure, the way they process information, and the process of interacting with chemical signals. For example: men have more information-containing gray matter structures, but women have more white matter, which are connected to different parts of the brain. Moreover, women have larger memory centers than men.
  8. Women’s day and night patterns may be shorter than 24 hours. (Usually there are 6 minutes short in a day.) Men are more likely to be night owls. But in the case of insufficient sleep, women’s overall performance will be better than men.
  9. During exercise, women’s bodies mainly burn fat; men burn carbohydrates.
  10. The average testosterone concentration in adult women is about 15-70 nanograms per male (ng/dL), and the average adult male is about 270-1070 nanograms per male. After the age of 30, the concentration of testosterone in men will drop by about one percent every year, but this phenomenon does not occur in women. However, after menopause, the concentration of estrogen decreases.
  11. Men have an Adam’s apple because their throat is larger, which makes the surrounding cartilage more prominent.
  12. The bone mass of men and women will peak around the age of 30. At the age of 40, both men and women begin to lose bone, and menopause accelerates bone loss in women. Therefore, women aged 51-70 need to consume 200 milligrams (mg) more calcium than men of the same age. Therefore, women need 1,200 mg per day and men 1,000 mg per day.
  13. Men’s daily calorie needs are higher than women. There are several reasons for this: higher muscle mass, height, and basal metabolic rate; and the same weight of muscle burns more than twice the calories of fat.
  14. Men and women have different body fat levels. Women have more body fat (about 10%), which is mainly used to maintain the functioning of the reproductive system. The best example is that when a woman’s body fat is too low, menstruation will stop.
  15. Women’s body fat usually accumulates in the buttocks and thighs, while men’s fat is mostly accumulated around the stomach.
  16. The difference in body size, muscle mass, and calorie requirements between men and women shows that men generally require a diet with a higher protein content.
  17. A study found that men’s resting heart rate is lower than women’s, but women’s peak heart rate is lower. During exercise, the heartbeat of men usually increases faster, and then slows down more quickly.
  18. Men usually have more red blood cells (4.7-6.1 million red blood cells per microliter, while women have 4.2-5.4 million red blood cells per microliter).
  19. Women’s blood pressure is usually lower than that of men, regardless of race or ethnicity.
  20. For most of their lives, men and women have the same vitamin D requirements; but elderly women need to increase their vitamin D intake to promote calcium absorption.
  21. Men seldom have regular physical examinations. When going to the doctor, they are more likely to hide or lie about their symptoms.
  22. Men and women have similar needs for zinc. But pregnant women and postmenopausal women need more zinc. Both men and women store zinc in the bones, but men also store zinc in the prostate.
  23. Men are not very sensitive to cold temperatures.
  24. Women have better sense of smell and taste. There are more than 50 cells (neurons) in their olfactory bulb, which is the part of the brain responsible for processing smell. Women also usually have more taste buds than men.
  25. Part of the difference between the way men and women look at the world is partly due to physiological reactions. On average, men are more likely to become colour-blind, but their eyes are also more able to perceive movement; women are more able to distinguish small colour differences.

This is fun, then?

When you know these phenomena that make men and women different, you can bring up these interesting facts in daily conversations whenever you want. Now you can also use these differences to make personal decisions about your health. If you are a woman, you know that you need more folic acid and will burn fat during exercise. If you are a male, you know that you need more calories and fat will accumulate around your stomach. These are important considerations when planning a healthy lifestyle.

What you should not do is to use the differences between men and women to emphasize gender advantages. All the differences listed above have very good biological or physiological reasons. Through human history, these differences have helped men and women survive, and most of them have come from cooperation.

These gender differences should not be regarded as limitations in all aspects. These are just averages and typical situations. Not all men are stronger, and not all women have a better sense of taste. Don’t let the differences between men and women prevent you from achieving your health or life goals.

Differences Between Mixtures and Compounds

A mixture contains two or more substances mixed, but not chemically as well as not in indirect quantities while a compound contains two or more elements that are combined chemically and in a fixed ratio. For example, seawater, crude oil, mineral oil, alloys (copper, bronze) and so on are some mixtures, water (H2O), hydrogen peroxide (H2O2), sodium chloride (NaCl), baking soda (NaHCO3) and so on are the names some compounds.

Like the classical theory of physics, anything that occupies space has a mass and volume known as matter. Even things can be classified into two classes, mixtures, and pure ingredients. Pure ingredients are made up of elements and compounds.

The elements are simple materials and cannot be broken down into simpler forms. It contains only one atom of type, but a compound has two or more different atoms or elements, on the other hand, a mixture contains different substances.

In order to highlight the differences between mixtures and compounds in this content, we will give a brief description of them.

Comparison Chart

Definition of Mixture

When we look we find many things around us are mixed, such as air, rocks, oceans, and even the atmosphere. These have mixed constituents with physical properties and not with any chemicals and not in a fixed ratio. Thus, we can say that the formation of a mixture occurs by mixing two or more substances, but not in a fixed ratio.

In a mixture there is no chemical reaction, fusion occurs physically. Thus a mixture has two or more different types of atoms or molecules, or at least one atom and one molecule. The mixture has no fixed melting or boiling point.

Mixtures can be separated by physical methods such as filtration, pouring, distillation. The mixture can be either homogeneous or heterogeneous.

Homogeneous Mixture

This is considered a true solution, as the constituents present in this type are equal or evenly distributed. For example sugar solution, mixture of alcohol and water, etc.

Heterogeneous mixture

When the constituents are not evenly distributed in a mixture, it is known as a heterogeneous mixture. For example, oil and water when mixed, a mixture of sulfur and iron, gravel, etc.

Apart from the above two things, the mixture will be classified based on the type of particle size found in it. These are solutions, suspensions, colloids.


This contains nano size particles, which are less than 1nm in diameter. The solution cannot be separated by the pouring method or the centrifuge method. Oxygen dissolved in water, air, gelatin are some examples.


In this solution, the particles are so small, that these cannot be seen through the naked eye, the particle size varies from 1nm to 1mm. The colloidal solution shows the Tyndall effect, the colloidal constituents can be separated by the process of casting and centrifugation. Blood, smoke, cream are some examples.


This is a kind of heterogeneous nature, they also show the Tyndall effect. These particles are quite large and can be separated by centrifugation or casting. Mud, granite, dust or pollutants in the air a little for example.

Definition of Compound

When two or more atoms of different elements are combined chemically to form a bond called a compound. It is a chemical mixture between different elements or elements. When bond formation occurs, the new compound forms chemical properties that are different from the components from which it is made.

For example, water (H2O), ethanol (C2H5OH), sodium chloride (NaCl), are part of common compounds, they are made up of a certain proportion of their elements and have a chemical identity as well. The different types of bonds are molecular, acid, cation, anion and binary bonds. All of these have different identities and chemical formulas.

Key Differences Between Mixtures and Compounds

Given below are the important points that distinguish the mixture from the compound:

A mixture is an impure substance, consisting of two or more physically mixed substances and not in a fixed ratio. A compound is a pure form, consisting of two or more elements of a chemical mixture and in a constant ratio.

  • Mixtures can be homogeneous or heterogeneous, but compounds are generally homogeneous.
    As mentioned earlier, the composition of the substances present in a mixture is not in a fixed quantity, this means that the ratio varies, but in the case of elemental compounds present in a fixed quantity, this means that the ratio is fixed. Therefore, these compounds can be named and have specific chemical formulas such as Sodium Chloride (NaCl), Baking Soda, Methane, Salt, etc., but these are not the same for mixtures.
  • Since the ratio of the substances present in the mixture is not fixed and its properties are also different (not fixed) as it depends on the type of material and the quantity of the elements being mixed, whether chemical or physical properties. In compounds, new properties (physical and chemical) are retained after the formation of a new compound, and we know the quantity or ratio of the elements present in the compound.
  • Separation of the substances present in the mixture is easy by different physical methods such as filtration, chromatography, evaporation, while in the case of compounds the substances are not easily separated and performed when compared to chemical methods.
  • No new substance is formed from a mixture, due to the irreversible properties of its constituents, while there is always the formation of new substances, due to the mixing of the chemical properties of different elements.
  • No heat change or energy involvement is observed when the mixture is made, but the formation of the compound results in a heat change as energy is applied or evolved in the reaction. The mixture has no melting or boiling point, but the compound has diluted melting and boiling points.
  • Examples of mixtures are alloys such as copper, bismuth, chromium, seawater (salt and water), gas mixtures, etc., while Sodium Chloride, Baking Soda, Methane, Salt, etc.

In conclusion

The information mentioned in this article is not applicable in science, but can be observed in everyday life; therefore it is necessary to know all these terms in detail to identify and distinguish them.

What is the Difference Between Mitosis and Meiosis?

Most people get injuries, which are complex or simple like bruises and, over time, these injuries heal. This healing process may be done through cell division in which a single cell divides to form two or more cells and the process continues like a cycle. This process helps living things grow, for example, more than 2 trillion cells divide each day in humans. There are two types of cell division processes, mitosis and meiosis, each with different characteristics.



A single cell divides into two genetically similar cells. The process is asexual and the resulting cells have the same number of chromosomes in each diploid cell, each with the same nucleus.


Meiosis is the process of sexual cell reproduction in which one cell divides its homologous chromosomes equally to form two haploid cells with half the number of stem cell chromosomes.

Mitosis process

Mitosis occurs in five phases that detail the changes through which the cells go. These stages are prophase, prometaphase, metaphase, anaphase, and telophase.

In prophase, chromosomes dissolve in the nucleus while centrioles move in pairs to opposite sides in the nucleus. As this process continues, the spindle fibers begin to form bridges from one end of the cell to the other.

In the next phase, prometaphase, the nucleus that envelops the chromosome begins to rupture and, now without a nucleus, the sister chromatid becomes independent. Long protein chains form the entire cell and are attached to the kinetochore (protein) which is in the center (centromere).

In the third phase, metaphase, kinetochore microtubules induce and attract sister chromatids. The chromosomes are then united in preparation for division.

In anaphase, the two chromatid sisters divide and move toward the cell pole. Although the kinetochore holding the fixed microtubules is attached to the centromere, it begins to shorten in length, while the second group of microtubules not attached to the kinetochore begins to lengthen. The whole cell then begins to stretch and pull in the opposite direction.

Finally, the process enters the telophase stage where each identical chromosome reaches the end pole of the cell while the spindle fibers begin to disappear. On each chromosome, the nuclear membrane forms and forms the nucleolus within each nucleus.

Although not considered part of the mitotic phase, the final process in mitosis is cytokinesis in which cells physically divide before the process begins again.

Meiosis process

Meiosis produces two different cells with half the number of chromosomes compared to the stem cell thus increasing genetic variation. There are two main steps of meiosis; meiosis I and meiosis II. The process of meiosis is important because it reduces the number of chromosomes in an egg or sperm to one set and also allows for the propagation of more than one pair of parental chromosomes.

Meiosis I

Meiosis I has four phases. In the first phase, prophase I, chromosomes appear, the nuclear membrane disappears, and centrioles begin to build spindle fibers to cover the chromosomes. The chromosome then splits into two sister chromatids whose centromere is held together. Thus, this process means that there are two sets of sister chromatids (four chromatids) in two chromosomes. Two non -cat chromosomes cross because the other two remain. Second, in metaphase I, chromosomes line up in the center of the paired spindle fibers. The third phase, Anaphase I, creatures when the same number of chromosomes are divided. In the final phase, telophase I, daughter cells completely divide, chromosomes disappear, and a nuclear membrane is formed.

Meiosis II

Meiosis II also has four phases in meiosis I. First in prophase II, centrioles form spindle fibers as the nuclear membrane disappears and chromosomes become more visible entering into metaphase II where chromosomes are again united in the middle along the spindle fibers. In anaphase II, the chromosome divides into two chromatids that each contain a piece of DNA then the cell divides. Finally, the shape of the nucleic membrane produces four new cells each with different DNA. In men, four cells form sperm while in women, only one cell becomes an egg and the remaining three are reabsorbed into the body.

Summary of Differences

Meiosis occurs in humans, animals, plants, and fungi to produce new genes after a homologous pair. The process of meiosis includes two parts that produce four haploid cells. This process only produces sex cells. Mitosis occurs in all organisms to produce all cells except sex cells. In mitosis, homologues are not paired and division occurs only once to produce 2 identical cells.
