1. Nonrandom mating occurs when certain individuals contribute more to the next
generation than others.
2. Males with albinism do not work in the fields for fear of sunburn, so they stay back with
the women and reproduce more passing down the t

Physiology is the study of the functions of the body
1. Mechanistic approach: mechanisms of action are emphasized.
How does a system work!
2. Teleological approach: explained in terms of fulfilling a b
1. It is a mobile army of about 2 trillion cells, the biochemicals they release, and
the organs where they are produced and stored. Genes confer immunity by
providing susceptibilities or resistances to certain infectious diseases.
2. An antigen
1. Proteins consist of one or more long chains of amino acids called
polypeptides. Some functions are to transport iron in the blood, provide
immunity, digest food, clot blood, regulate glucose, form skin, hair and
muscle; and enable cells to m

All stages of development.
Sperm and oocyte
The clitoris is similar to the penis. They both release a sex cell.
The epididymis. They are located outside of the abdomen because it is a
cooler location needed for sperm to develop.
