Answer:
<em>Evolutionary approach</em>
Explanation:
Evolutionary psychology can be described as a branch of psychology under which theoretical approaches to certain behaviours and their relationship to evolution and natural selection are studied. In simple terms, this evolutionary approach tends to explain that how evolution has influenced and shaped our mind and our behaviour. It is the relationship between evolution and behaviour and hence shows a broader relationship between the fields of evolution and psychology.
In general, the term organelle is used for the small structures within a cell.
Answer:In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.
Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.” The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific genes.
