What are some examples of how a cell's structure relates to its function in the body?
irakobra [83]

The structure and shape of each type of human cell depends on what function it will perform in the body. For example, red blood cells (RBCs) are very small, flat discs, which allows them to easily fit through narrow capillaries and around sharp corners in the circulatory system to deliver oxygen throughout the body.

The elongated shape of muscle cells allows the contraction proteins to line up in an overlapping pattern that makes muscle flexing possible.

And human sperm cells’ structures allow them to “swim” long distances to reach an egg for fertilization

dolphi86 [110]

Answer:

C. Cutting down forests.

Explanation:

Carbon dioxide is an inorganic gaseous molecule with the chemical formula, CO2. It is naturally released into the atmosphere via a lot of processes. However, CO2 is the most important greenhouse gas as it contributes the most to the global warming effect of the Earth.

The effects of an increase in CO2 concentration in the atmosphere is as follows:

- increase in water contamination and floods

- ocean acidification

- reduction of cold-related deaths

However, the cutting down of forests is not an effect of an increase in CO2 concentration but rather a cause.
