What statement best illustrates how an organism maintains homeostasis ?

a)female barn swallows mate with long-tailed males.

b)desert pack rats are active at night to conserve water.

c)parents pass their traits to their offspring.

d)young hawks have different kinda of feathers than adult hawks

B) Desert pack rats are active at night to conserve water.

Explanation:

Homeostasis is the ability or quality of the body to maintain the internal temperature constant and stable with respect to the changes occurring in the external environment. This involves maintenance of the internal temperature, pH, and conservation of water.  

B is the correct option this is because of the fact that in desert water conservation will be the beneficial adaptation. The rat may experience dehydration in day but water will not be lost in night. This will help in maintaining the homeostasis.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
