You conduct a study on the selection of traits in a population of wild hippopotamuses. You notice that compared to the smaller baby hippopotamuses, the larger baby hippopotamuses survive more often because potential predators are intimidated by the larger baby hippopotamuses. What type of selection is happening with the baby hippopotamuses? (This is a terrible scenario sorry)
Directional selection
Name the type of inhibition in which the product of a catalytic reaction inhibits the original enzyme.
Feedback inhibition
This vascular tissue in plants, made up of living cells, transports sugars and amino acids throughout the plant by active transport.
Phloem
The cytoskeleton is a fundamental element in cells that provides many functions. Name the three components of the cytoskeleton.
Microfilaments (actin filaments), intermediate filaments, and microtubules
An organism initially has a diploid set of 72 chromosomes. After undergoing meiosis, how many chromosomes will each daughter cell have?
36
Name at least two examples of prezygotic barriers
Prezygotic barrier = obstacle before fertilization
ex. different mating seasons, geographic difference, different anatomy, etc.
This phylum contains starfish, sea cucumbers, and sea urchins.
Echinodermata

Amygdala
Which enzyme catalyzes the first committed step of glycolysis?
Phosphofructokinase (PFK) 1
Define silent mutation, missense mutation, and nonsense mutation
Silent mutation = no change in amino acid
Missense mutation = one amino acid substituted
Nonsense mutation = early stop codon
What is the term used in biology, and especially phylogeny, to refer to the idea that the most simple solution is usually the correct one?
