ANA 4200: Evolution

Explore what makes each element unique by focusing on the atomic components: protons neutrons and electrons. Learn why the number of protons known as the atomic number is the defining characteristic for each element's properties. Understand how protons set elements apart even as neutrons and electrons also play important roles.

Learn about mouse genetics and the implications of dominant and recessive genes on coat color. We'll use a Punnett square to predict offspring coat patterns by crossing two heterozygous mice. Learn how phenotype ratios like 9 Agouti: 4 white: 3 black help us understand genetic outcomes.

Unravel the intricacies of the Autonomic Nervous System (ANS) and its pivotal role in controlling involuntary bodily functions. Differentiate between the sympathetic and parasympathetic systems and their unique contributions. Debunk misconceptions surrounding the ANS's characteristics.
