Biology
2 answers:
kvv77 [185]2 years ago
8 0

Answer:

In animals, the process of respiration is aerobic respiration, exchange of gases takes place ( carbon dioxide leaving the cell, oxygen entering)

Single cellular organisms can exchange gases directly across their cell membrane through the process o diffusion.

Large animals cannot maintain gas exchange by diffusion across their outer surface. A respiratory surface is covered with thin, moist epithelial cells that allow oxygen and carbon dioxide to exchange. Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist.

Which could be a pathway of food through an ecosystem?​
algol13

Answer:

Sun > Grass > Deer > Lion

Explanation:

The sun begins a food chain because its light is needed for a plant, in this case grass, to grow.

An animal that eats grass is the deer, who is a primary consumer.

An animal that eats deer is the lion, who is a tertiary consumer in this case.

The lion has no natural predator, and thus is at the top of this food chain.

This ecosystem can be one found where grass, deer and lions exist, for example, the deciduous forest in the eastern United States.

Why might having an excretory system that excretes urine be a disadvantage in a desert environment? how can desert animals overc
Pani-rosa [81]
<span>In a desert, water is in scarce supply, so excreting water would be a bad thing and might cause the death of any animal that does so due to dehydration. There can be several different mechanisms to overcome this. One would be to have the bladder discharge urine into the large intestine where the water can then be reabsorbed into the body while the urea in the urine is passed out along with other solid wastes produced by digestion. Some other methods of conserving water would be for the kidneys to extract more water from the urine leaving the urine fairly concentrated. Also animals may behave in manners that conserve water such as staying in the shade during the day and only being active at night.</span>

Explanation:

Functionalists perspective of gender roles view conventional gender roles as necessary to commit to family functioning as it tends towards keeping the family balance: Women take on the “expressive” character of putting up with household chores and giving emotional care, grooming and nurturing of family members, while men take on the “instrumental” character of acquiring income and undertaking important family decisions.
