a) Photosystem I
b) Photosystem II
c) Calvin cycle
d) Production of oxygen

This process uses memory cells to mount a faster, stronger immune response upon re-exposure.
What is Acquired immunity?
This growth type creates a J-shaped curve and occurs when resources are unlimited.
What is exponential growth?
This cycle uses CO₂ to make glucose and occurs in the stroma.
What is the Calvin Cycle?
24. There were 6,300 Snow Leopards in a recent population estimate. If there were only 10

What would be the size of a population at the end of a
time period if N1 = 50, b = 0.6, d = 0.1 and K = 100?
62 individuals
This type of T-cell destroys virus-infected or cancer cells.
What are cytotoxic T-cells?
A population of kangaroos starts with N₁ = 250.
Over one year, there are 30 births and 10 deaths.
Find:
Growth rate (r)
Population size next year (N₂)
Growth rate (r): 0.08
Next population (N₂): 270 kangaroos
These reactions require light and produce ATP, NADPH, and oxygen.
What are the light-dependent reactions?
25. One should predict the offspring of parents that survive a plague should ...
a) produce antibodies to fight off the disease at birth
b) have alleles for antibody production similar to their parents
c) never be infected by that disease
d) already possess the same memory cells as their parents
b) have alleles for antibody production similar to their parents
You are studying a different population of Nerf Herders who are living
on a lush planet (not Hoth). There are also 100 Nerf on this planet
(N1=100). r=.05; G=5; K=150
What would the N2 population size be on this lush planet?
A) N2=98.34
B) N2=101.67
C) N2=105
D) N2=150
b) 101.67
These cells are the first responders and perform phagocytosis to fight bacteria.
What are neutrophils?
A population of sea otters has:
N1=600N_1 = 600N1=600
r=0.10r = 0.10r=0.10
K=1,000K = 1,000K=1,000
Find:
Predicted growth (G) and new population size (N2)
Growth (G): 24
Next population (N₂): 624 otters
This flow of protons drives ATP synthase in chloroplasts.
What powers ATP synthase?
Koalas in Australia are currently under extreme distress. Wildfires and climate change have
drastically reduced their habitat and started making their food less nutrient dense.

a) density-dependent
b) density-independent
c) exponentia
b) density-independent

rejected?
a) B-cells respond to antibodies present
on the organ.
b) Macrophages respond to antibiotics on
the organ.
c) B-cells respond to antigens present on
the organ.
c) B-cells respond to antigens present on the organ.
