The answer is The law of ''gravity'' helps explain why the density of air as the altitude above earth's surface increases.
Genetic drift is defined as a shift in the allelic frequency of a population. This can be caused by natural selection which is the differential survival and reproduction of individuals across a population due to differences in phenotype. Natural selection favors particular traits in a population hence these individuals are able to reproduce while the individuals with disadvantageous traits will pass their genes to succeeding generations. This way the allelic frequency of succeeding generation will be diferent from that of the parent population.
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). ... Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).
Remember that a biotic factor is a living component in an ecosystem that affects the population of another organism. So that means that the answer is B.
