Answer:
Mechanisms enabling one cell to influence the behavior of another almost certainly existed in the world of unicellular organisms long before multicellular organisms appeared on Earth. Evidence comes from studies of present-day unicellular eucaryotes such as yeasts. Although these cells normally lead independent lives, they can communicate and influence one another's behavior in preparation for sexual mating. In the budding yeast Saccharomyces cerevisiae, for example, when a haploid individual is ready to mate, it secretes a peptide mating factor that signals cells of the opposite mating type to stop proliferating and prepare to mate (Figure 15-2). The subsequent fusion of two haploid cells of opposite mating types produces a diploid cell, which can then undergo meiosis and sporulate, generating haploid cells with new assortments of genes.

Answer: (A) Genetic drift
Explanation:
The genetic drift is one of the process of random sampling in which the existent gene frequency are get changed in the organisms and it is also refers as the allelic effect.
According to the given question, In a small remote area the different types of people are living and in that area the "Blue skin" condition is highly incidence due to the variation in the hemoglobin structure.
So, the high frequency in the Blue skin in that specific area is one of the example of the genetic drift and the main role of the genetic drift is to determining the sampling error from the different generation gene.
Therefore, Option (A) is correct answer.
Answer:
In photosynthesis carbon dioxide is fixed and oxygen is released. In breathing, oxygen is consumed and carbon dioxide is released, releasing energy.
