Answer:
Deleterious alleles appear sporadically in a population
Explanation:
A population with a deleterious allele will have no or few individuals that have the ability to pass along these traits. These alleles appear less in a population because of selective pressure but they are not always absent. The alleles appear less often but are are not always passed on and the others that are genetically fit are able to pass along their genes. The reason the population equilibrium is not zero is because these alleles do appear but they are not necessarily passed along. These individuals may not be able to reproduce or reach the age of reproduction.
Deleterious alleles appear more often, making individuals less fit genetically, i.e. they pass fewer copies of their genes to future generations. Put another way, natural selection purges the deleterious alleles.
I am sure that it is Typhoons which is a tropical storm in the region of the Indian or western Pacific oceans.
Blood clots will do this. Cutting off blood flow while also increasing blood pressure. Also, if the viscosity (thickness of the blood) is thick which will slow down the flow and cause the body to use more effort to pump blood.
Explanation:
Results in a decline in CD4+T cell numbers below the critical level, and loss of cell-mediated immunity. Therefore the body becomes progressively more susceptible to opportunistic infections and cancer.
Answer: A. Plant
Explanation:
Plants have some of the most of complex cells of living organisms because they have different roles and structures to enable the plant to survive.
These include cells like the Parenchyma, Collenchyma, Sclerenchyma, Xylem and Phloem cells. Xylem cells for instance are complex cells located within the vascular tissues of plants and help transport water and minerals to the rest of the plant from the roots. Xylem cells look long and tracheal which is to enable them carry out the aforementioned roles.
