The study of molecular biology is concerned with life at the level of cells and molecules, their structure and function.
Physiology: how the nervous system and hormones work, how the brain functions, how changes in structure and/or function can affect behavior.
For example, we could ask how prescribed drugs to treat depression affect behavior through their interaction with the nervous system.3.
This will enable you to arrange your critical sources into a logical, coherent order, providing a structural framework for the overall piece.
Because molecular biology is a scientific pursuit, your essay will take an evidentiary perspective, presenting empirical research, analysing results, and discussing future avenues of enquiry.
In effect, your essay needs to describe the way these individual phenomena are related; explaining how molecular events lead to the hierarchical organisations of living cells, known as organisms.
Accordingly, your essay will draw on insights from other, related spheres of biological science, incorporating biochemistry and genetics in particular.
It is the only approach in psychology that examines thoughts, feelings, and behaviors from a biological and thus physical point of view.
Therefore, all that is psychological is first physiological.
There are two types of twins: Research using twin studies looks for the degree of concordance (or similarity) between identical and fraternal (i.e., non-identical) twins.
Twins are concordant for a trait if both or neither of the twins exhibits the trait.
