Distribution of phenotypes within a population may be impacted by different types of natural selection. These types of selection include;
Directional selection involves a change in the environment shifts of phenotypes observed. Example is the giraffe neck-length, where the length got longer and longer over time to reach the leaves at the top of trees.
Stabilizing selection , this is a selection where an average phenotype is favored. example is number of eggs laid by birds such that too many eggs will be a waste of energy because some chicks would starve.
Disruptive selection is a selection where individuals with an average value of a trait are affected most while those with values below average are affected least. Example small individuals are capable of hiding from predators while big individuals can not fit in the hiding place but instead will fight with predators.

Answer:
oxytocin
Explanation:
The pituitary gland is a small gland that divides into two distinct portions, the anterior and posterior lobes, and is located at the base of the brain.
The anterior pituitary, also known as the adenohypophysis, secretes six important peptide hormones, they are:
- The growth hormone;
- Adrenocorticotropin;
- The thyroid stimulating hormone;
- Prolactin;
- Two gonadotropic homons - FSH and LH;
Oxytocin is not a hormone produced by the anterior pituitary but by the posterior pituitary, which is known as the neurohypophysis.
It is false that Qualitative research generally uses numbers to represent research data. Qualitative research is more on descriptions and meanings.Quantitative research is the word for this description.
