It is an example of directional selection.
The different kinds of natural selection can influence the distribution of phenotypes within a population. In stabilizing selection, an average phenotype is preferred.
In directional selection, a modification in the surrounding changes the spectrum of the observed phenotypes, and in diversifying selection the extreme values for a trait are preferred over the transitional values. This kind of selection usually pushes speciation.
The directional selection, in the field of population genetics, refers to a mode of natural selection in which an extreme phenotype is preferred over other phenotypes, making the allele frequency to change with time in the orientation of that phenotype.
Answer:
The correct answer is - Archaea or archaebacteria.
Explanation:
Archaea is the domain and the kingdom of the single-cell prokaryotic organisms as they lack a nucleus. These organisms are present in extreme habitats such as hot springs, high saline water. These organisms can live in extremely aggressive environments which makes it a uniqe characteristic of this organism.
In the given condition the organism that lives in hypersaline water is most likely a member of the Archaea domain or Archaebacteria kingdom as it is found in the hypersaline waters of Southeastern Australia and unicellular organisms.
Both are found in all eukaryotic cells is the one among the following choices given in the question is not one of the features that is common in mitochondria and chloroplasts. The correct option among all the options that are given in the question is the third option or option "C". I hope it helps you.
Plankton.......................................
On top of each kidney lies Adrenal gland. It's part of endocrine system. It's responsible for producing hormones like adrenalin, also steroids like aldosterone and cortisol. So in this case answer to your question is Adrenal gldans lie on top of kidneys
