I hope this helps! ^-^
Answer:
C
Explanation:
Resource availability may be the selection pressure, however, it will not lead to evolution. Evolution is by chance whereby offsprings accumulate mutations that result in phenotypic changes that may allow them to access other sources of food.
Answer: yes because they're more energy is transferred which increases the kinetic energy which increases the temperature because temperature is the average amount of kinetic energy
The differentiation is based on a set of activation / inactivation of genes (parts of DNA) via complex cascades of regulation. We can not consider a differentiating cell individually. Indeed, its "expression profile" depends on its environment: cell-cell interactions, cell-matrix. It is these extra-cellular signals that will trigger the internal regulation signals. The establishment of plans for the organization of a Drosophila embryo or the development of limb buds in mice are well-known models. In these models, so-called "positional" information plays a large role: a substance present in the form of a concentration gradient in the extracellular medium will trigger or not intracellular signals depending on the dose at which the cells are exposed along this gradient.
