"We Have Different Appearances" Biological Diversity PPT Courseware

If we were asked to identify a certain classmate in the class, we would do it effortlessly. Have we ever wondered why?

Observe our differences

In the group, what are the similarities and differences between our looks?

What do we find when we compare everyone with the same facial features?

Through observation and comparison, we will find that people may be the same or different in terms of a certain facial feature. For example, two people have double eyelids, while another person has single eyelids.

Are our looks unique?

Which of our physical features are the same and which are different? If two facial features are combined, how many different types of people will there be?

genetics

It refers to the genetic material that carries information about the biological characteristics of the parents. Our appearance is affected by our genetics.

However, acquired growth variations, living environment, etc., also affect our appearance to a certain extent, such as wounds, acne, etc.

Genes refer to the genetic material that carries information about the physiological characteristics of parents and are the basic genetic units that control the physiological traits of offspring. Genes express the genetic information they carry by directing the synthesis of proteins, thereby controlling the characteristics of individual organisms, including gender, personality, appearance, etc.

Genes exist in the reproductive cells (sperm and eggs) of parents. Even if it is the same person, although the genetic information they carry has many similarities, each of his reproductive cells also has some differences.

Nutrients include protein, fat, carbohydrates, inorganic salts, fiber, vitamins and water. These nutrients play a huge role. They can form body tissues, make people grow taller and gain weight, provide the calories needed for body activities, and regulate the physiological activities of various systems in the body.

Lifestyle refers to a person's habitual way of eating and living, from the taste of food, the speed of food intake, the habit of behavior, to the regularity of work and rest patterns, etc. Over time, people form some relatively stable habits and attitudes.
