What are the monomers of each of the 4 macromolecules AND what are the functions of each of these macromolecules?
Carbohydrates: Monosaccharides, provide short term energy
Lipids: Fatty Acids, provide long term energy OR makeup the cell membrane
Proteins: Amino Acids, Enzymes OR structure OR transport
Nucleic Acids: Nucleotides, store genetic information

List three differences between mitosis and meiosis
Mitosis: 1 round of division, makes 2 identical daughter cells, makes diploid somatic cells
Meiosis: 2 rounds of division, makes 4 unique daughter cells, makes haploid gametes

Mr. Gomez
How does the lysosome help our cells maintain homeostasis?
It recycle wastes, macromolecules, and cell parts into monomers
What is the primary difference between a positive feedback loop and a negative feedback loop?
Positive feedback loops promote their initial stimulus (e.g. injured tissues releasing chemicals in blood that activate platelets to facilitate blood clotting) while negative feedback loops inhibit their initial stimulus (e.g. insulin reducing high blood glucose to normal levels)
Color blindness is an X-linked trait. If a woman who had a healthy father and a color-blind mother has a child with a healthy man, what is the % chance that their child is a carrier for color-blindness?
25%
What are the three conditions that must be met for Natural Selection to occur in a population?
1. More offspring are produced than can be supported by the environment
2. There is heritable variation among individuals
3. Variations lead to differential fitness among individuals
