Cell membrane of a cell is responsible for the substances
that goes in and out of the cell’s cytoplasm and organelles. It is transports
different materials externally to internally and vice-verse. Hence the cell
membrane is like
<span><span>1. </span>The wall,
window and door of a house.</span>
<span><span>2. </span>The
security guard of a certain bank</span>
<span><span>3. </span>Or the
military sector of a country.</span>
Like these three real-life examples, they regulate and
control the flow of certain entities from outside to inside and vice-versa.
Answer:
Hypothesis: If mucus production in the submucosal layer of the esophagus is insufficient, cell longevity is affected, because it interferes with the quality of connective tissue.
Explanation:
In a scientific research the hypothesis is an assumption, a possibility that will justify the purpose of the scientific research and will help in the establishment of all the steps of this research, so that it is possible to determine if the hypothesis is true or false. In other words, we can say that the hypothesis must be formulated as an assumption, before the research that will prove it or not.
An example of a hypothesis about research on the longevity of cells that line the esophagus is: "If mucus production in the submucosal layer of the esophagus is insufficient, cell longevity is affected, because it interferes with the quality of connective tissue."

Greater genetic diversity, compared to asexual reproduction.
If you think about it, this makes sense because in asexual reproduction, an organism reproduces all by itself, and uses its own genome as the blueprint for its' offspring. However with sexual reproduction, two organisms come together, each contributing half the required chromosomes, and the offspring gets 1/2 it's genes from the mother and 1/2 it's genes from the father. Sexual reproduction allows for greater diversity because it doesn't just rely on mutations to add new diversity to the genepool.
