Compare and contrast the characteristics of the ideal tissue forming the outer surface of the body with that forming the lining

julsineya [31]

The tissue that forms the outer surface of the body is a stratified squamous keratinized epithelium. The surface layer of dead cells(stratum corneum) is made to keep things out of the body, protecting it. The tissue that lines the digestive tract(e.g. intestine). Is made from 1 layer of columnar cells that facilitate the absorption of nutrients. Both tissues are epithelia.

alexgriva [62]

Answer:

C. Cholesterol

Explanation:

Cholesterol maintains the fluidity of the cell membrane and thereby, regulates its function.

Bile acids are derived from cholesterol which serves as their precursor. For example, Taurocholic acid is a polar derivative of cholesterol. Bile acids serve in the absorption of fatty acids, glycerol, and fat-soluble vitamins as these compounds are non-polar in nature.

Vitamin D is produced when the derivative of cholesterol, 7-dehydrocholesterol undergoes photolysis in skin cells in presence of sunlight.

Nina [5.8K]

Answer:

This question is incomplete and lacks options, the whole question is:

Plant hormones serve as chemical messengers between cells and tissues. Auxin is a plant hormone that causes the cells on the shady side of a plant shoot to elongate. The response enabled by auxin is known as -

Options are:

A. geotropism

B. transpiration

C. phototropism

D. photosynthesis

The correct answer is c.

Explanation:

Phototropism is known as a natural and organic movement of a plant towards the light. This is due to the natural ability of a plant to change direction based on changes in lighting in the environment. But external stimulus is not enough. It must generate some changes inside the plant that make it react in this way: hormones. A hormone is a chemical substance produced in one tissue and transported to another, in which it exerts one or more highly specific effects.Auxins are members of a group of plant hormones that are more beneficial to stimulate plant growth, it is the responsible mechanism of the response to phototropism in plants, which tends to be concentrated in the region of the stem and leaves, when a plant lacks this, it can be noted since the bending towards the light source is little or no, that is, auxins make the cells of the stem growth region (rhizomes and stems) lengthen.
