Question 1

Which of the following graphs illustrates the growth curve of a population of snowshoe hares over several seasons in northern Canada?

Accepted Answer

The answer of Which of the following graphs illustrates the...

Question 2

When levels of CO₂are experimentally increased, C₃plants generally respond with a greater increase in productivity than C₄plants. This is because

Accepted Answer

C3 plants are more limited by CO2 availability due to their higher rates of photorespiration, which is reduced when CO2 levels are increased, leading to greater productivity gains compared to C4 plants.

Question 3

If $ \psi $_P= 0.3 MPa and $ \psi $_S= -0.45 MPa, the resulting $ \psi $ is

Accepted Answer

The resulting $ \psi $ is calculated by adding $ \psi $_P and $ \psi $_S: 0.3 MPa + (-0.45 MPa) = -0.15 MPa.

Question 4

Which of the following seems to be the known upper and lower size limits of genomes?

Accepted Answer

The known upper and lower size limits of genomes range from about 1 Mb to 580,000 Mb, covering the smallest bacterial genomes to the largest plant genomes.

Question 5

The following questions refer to this information: 
In the year 2500, five male space colonists and five female space colonists (all unrelated to each other) settle on an uninhabited Earthlike planet in the Andromeda galaxy. The colonists and their offspring randomly mate for generations. All ten of the original colonists had free earlobes, and two were heterozygous for that trait. The allele for free earlobes is dominant to the allele for attached earlobes
-Which of these is closest to the allele frequency in the founding population?

Accepted Answer

The allele frequency for the dominant allele (A) is 0.9, and the allele frequency for the recessive allele (a) is 0.1. This is because two of the original colonists were heterozygous for the trait, meaning that they had one copy of the dominant allele and one copy of the recessive allele. The other eight colonists had two copies of the dominant allele.
