Basic Biology Genetic diversity describes the genetic differences seen among members of a population. What this means that that every individual on the planet is different from one another in some way.

If we happen to live in a gene pool that has a high concentration of genetic diversity‚ then we are more like to have many different genetic combinations

Introduction to Biology‚ Lesson 3 Essay Questions: Compare and contrast directional selection and disruptive selection‚ and provide an example of each. Both of these show the distribution of phenotypes. In directional selection‚ the distribution of phenotypes forms a "bell curve." Selection against one of the extreme phenotypes causes the distribution to move in one direction or the other. An example might be plants whose flower color is determined by incomplete dominance: white‚ pink‚ or red

example of an everyday hero is a firefighter. Firefighters are very courageous‚ they risk their lives every day in order to keep us safe.

I believe that heroes are made‚ not born because you never know what life is going

The function of a capsid‚ in virus biology‚ is to serve as a protective outer layer that protects the genetic material of the virus from the host’s defensive cells. The capsid is made up of proteins. The nucleic acid is what is contained within the capsid‚ which is a group of long‚ linear macromolecules‚ consisting of either DNA or RNA. There are two different cycles in which the virus uses a host cell to replicate and reproduce itself. These two cycles are known as the lytic cycle‚ and the lysogenic
