An insect called the European corn borer can reduce the amount of corn from corn crops. To protect corn from this insect, scientists genetically modified corn plants. The scientists inserted a gene into the genome of corn plants. The gene codes for the production of a toxin that can kill the corn borer.
What will most likely happen within the corn borer population over time?

Corn borers will produce new genes and will become less common.

Corn borers that can reproduce asexually will become more common.

Corn borers that start eating other insects to avoid the toxin will become less common.

Corn borers with resistance to the toxin will survive to reproduce and will become more common.

A Siamese cat has both dark and light fur on its body, as shown. The production of the protein that determines fur color is dependent upon temperature. The fur on the body of the cat is lighter colored because its body is warmer than its head, feet, and tail.
Which of the following best describes how fur color is determined in a Siamese cat?

Fur color is determined only by genes and RNA sequences that code for temperature.

Fur color is determined by proteins from the environment and the temperature of the genes.

Fur color is determined by a gene that codes for a protein and by the temperature of the environment.

Fur color is determined only by environmental factors that include genes and the temperature of the cat.

CYP1A is a protein in organisms that breaks down toxic substances such as those found in oil. The amount of CYP1A protein in an organism depends on the expression of the CYP1A gene. Prior to 2006, there was a large oil spill off the coast of Alaska that affected many organisms. From 2006 to 2014, scientists measured the amount of CYP1A protein in ducks sampled from two populations. One population was exposed to oil from the spill, and the other population was not exposed to oil. The results are shown.

These results show that, between 2006 and 2009, the amount of CYP1A protein in ducks exposed to oil was the amount in 2006. This evidence suggests that the amount of oil in the environment most likely the mRNA is

A. active transport

B. lipid storage

C. meiosis

D. mitosis

Which of the following could explain why a little brown bat population is slow to recover after many bats in the population die during an outbreak of WNS?

A. The bats have a low birth rate.

B. The emigration rate of the bats decreases.

C. The immigration rates of bat predators decrease.

D. The flying insects that the bats eat have low death rates.
