question 3.3. a developer wants to turn part of a local wants to turn part of a local woodlot into a new housing development. in the springtime, a vernal pool exists in the part of the woodlot marked for development. how might this proposed development affect the salamanders that live in the woodlot? (points : 1)
a. they would have no water to drink.
b. they would have no place to mate and lay their eggs.
c. it would have no effect on their population.

1. The right answer is response.

Response (or adaptation) can be defined in a general way as the functional adjustment of the living being in the middle, and, in particular, as the appropriation of the organ to its function.

Adaptation is the bringing together of a living organism with the external conditions. It perfects its organs, makes them more apt to the role they seem to play in the life of the individual. It puts the whole organism in coherence with the environment.

2. The right answer is heredity.

Heredity is the transmission, within a living species or a cell line, of characteristics from one generation to the next. The mechanisms of heredity are at the heart of the theory of evolution because they allow the accumulation of variations over generations that leads to the appearance of new species.

3. the right answer is B.

Deforestation is the phenomenon of regression of forested areas. It results from deforestation actions, linked to the extension of urbanization.

The destruction of forests leads to the disappearance of natural habitats for flora and fauna. The animal and plant species concerned are weakened, or may disappear if the available resources are no longer sufficient.

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.
