7.
Which of the following statements is true regarding carrying capacity?
a)
The carrying capacity for P. aurelia was reached on Day 14 and is 275 cells. This is the highest number.
b)
The carrying capacity for P. aurelia was reached at Day 10 when grown alone and Day 15 when grown with P. caudatum.
c)
The carrying capacity for P. aurelia when grown alone was reached on Day 5 and is 175 cells.

9.
Which of the following statements is a correct distinction between autotrophs and heterotrophs?
a)
Autotrophs, but not heterotrophs, can nourish themselves beginning with CO2 and other nutrients that are inorganic.
b)
Only heterotrophs require chemical compounds from the environment.
c)
Cellular respiration is unique to heterotrophs.
d)
Only heterotrophs have mitochondria.
10.
People who have Tay-Sachs disease cannot metabolize some lipids effectively. Tay-Sachs is a recessive disorder. A student used a Punnett square to determine the probability of offspring inheriting the disease. The results from a Punnett square are 25% TT, 50% Tt, and 25% tt. Which conclusion can be made regarding the genotypes of the parents and the probability of inheriting a Tay-Sachs allele?
a)
The parents must be TT and tt, which yields a 25% chance of expressing the disease.
b)
The parents must be Tt and tt, which yeilds a 50% chance of inheriting an allele for the disease.
c)
The parents must be TT and TT, which yields a 25% chance of inheriting an allele for the disease.
d)
The parents must be Tt and Tt, which yields a 75% chance of inheriting an allele for the disease.
11.
A scientist studied the energy contribution of different types of cellular respiration to a runner during an endurance running event . The scientist then created the graph shown from the data collected.
Which conclusion can be made regarding the mechanisms for obtaining energy in Line 1 and Line 2?
Which conclusion can be made regarding the mechanisms for obtaining energy in Line 1 and Line 2?
a)
ATP is obtained through aerobic respiration for Line 1 while anaerobic respiration occurs for line 2.
b)
ATP is obtained thorugh anaerobic respiration for Line 1 while aerobic respiration occurs for Line 2.
c)
Line 1 shows energy is obtained through production of glucose molecules while Line 2 shows energy obtained through the production of protein molecules.
d)
Line 1 shows energy is obtained through the production of fat molecules while Line 2 shows energy obtained through the production of carbohydrate molecules.
12.
a)

It allows the zygote formed from fertilization to have triple the chromosome number of the organism.
b)
It allows gametes to have twice the original number of chromosomes of the organism.
c)
It allows gametes to have half the original number of chromosomes of the organism.
d)
It allows the zygote formed from fertilization to have half the original number of chromosomes of the organism.
16.
The use of pesticides on crops has been a common farming practice for decades. What has been the greatest effect of natural selection through the use of pesticides on certain insect populations?
a)
Natural selection has been altered because the insects and their predators are killed.
b)
The rate of selection is increased because the pesticides do not kill the insects that are naturally resistant to it.
c)
The rate of selection has decreased because the pesticides kill only young insects.
d)
The pesticides have altered natural selection by causing the insect DNA to spontaneously mutate.
17.

b)
They kill a cell and reproduce inside it.
c)
They invade a living cell and use the cell's functions to replicate their genetic material.
