Answer:
They release chemical messengers to communicate with cells they may or may not be in direct contact with.
Explanation:
Unicellular organisms such as bacteria or yeast, 'talk' to each other through the release of chemicals. In bacteria, this is known as quorum sensing which allows them to determine the surrounding bacterial population density. In yeast, one of the more popular pathways is known as the mating factor pathway, which allow the organisms to find mates. Whereas, in multicellular organisms (such as humans), this chemical release allows for cell-cell co-ordination which keeps the system functioning correctly.

BUT I AM NOT 100% SURE!
Answer:
Will never go to fixation.
Explanation:
Mutation is the sudden, heritable change in the genetic sequence of the organisms. The mutation might cause the particular disease in the organisms.
The gene fitness leads to the increase in the gene frequency in the upcoming generations. The gene will fix in the population when their i no selection and no mutation. Since, the information given in the question states that mutation is acting, so the A allele will never fix in the population.
Thus, the answer is option (c).
