The answer is genetic diversity, Genetic diversity is the
total number of genetic features in the genetic makeup of a species. It is well-known
from genetic variability, which defines the tendency of genetic characteristics
to vary. Genetic diversity serves as a way for populations to adapt to changing
environments.
The answer is B, decomposers are like worms, they eat and break down stuff into soil
Since stomata are affected by [CO2] and water vapor content of the air, an environment with high water vapor content (water potential) and high CO2 levels will likely have the highest #of stomata. I.e. when plants have readily available water source and ample CO2 in order to maximize photosynthesis. As far as geographic environment I think it varies quite a bit and there are competing hypotheses from what I understand
C) According to Lamarck, long necked giraffes evolved because they spent the majority of their time stretching their necks and this trait was passed down to offspring; according to Darwin, Giraffes with long necks had the advantage in the environment and survived, reproduced, and passed this trait on to offspring.
