Answer:
The answer is option A: True
Explanation:
Exposure to environmental stress or pathogens is the fuel that ensures the fitness as well as the survival of species population. These factors leads to adaptation of the cells of the species to survive.
During both meiosis I and meiosis II, cells<span> undergo the same phases found in mitosis, but the processes and results are different. Within meiosis I, homologous chromosomes become paired and crossing over occurs. Homologous pairs are separated, and the two resulting </span>daughter cells<span> have half as many chromosomes per </span>cell<span>.</span>

Explanation:
The ocean plays an important part in the carbon cycle.
- Overall, the ocean is called a carbon 'sink' because it takes up more carbon from the atmosphere than it gives up.
- Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter.

Answer:
Smaller populations have a greater chance of having one allele expressed disproportionately.
Explanation:
Genetic drift corresponds to a drastic casual alteration of the natural order, reaching the genotypic concentration of one or several species, not preliminarily involving natural selection factors, but caused by sudden events. Such phenomenon is characterized by the occurrence of ecological catastrophes, for example: earthquakes, tsunamis, tornadoes, floods, burnings, avalanches and other processes, affecting a large population contingent. Thus limiting the genetic content of a particular group, restricted to the prevailing individuals.
In this situation, with low variability, differentiated individuals will experience a more significant selection pressure in relation to the ascending lineage, which minimized the achievements of selection due to the high number of living individuals. In this scenario, smaller populations will have a greater chance of having a disproportionately expressed allele as the number of members is reduced. We can also see this effect if by using a coin we imagine that heads and tails are two alleles in a population and each coin toss represents one member of that population.
