Question
7. Ultraviolet light can cause mutations and other damage within cells, which can hurt an individual's chance of surviving and leaving offspring. Some molecules can protect cells from damage by UV. The amount of these molecules is determined by genes. Within a population, some individuals make more of these UV-protection molecules than others.m What do you predict would happen to the frequency of the genes that cause more of the molecules to be made in a population over time? Assume all other factors are equal.
a. The frequency would increase because individuals need the genes.
b. The frequency would increase because individuals with the genes for more molecules would leave more offspring.
c. The frequency would decrease because molecules are types of chemicals, and having more chemicals in the body is harmful.
d. The frequency would stay the same because populations do not change over time.
8. Write down the evidence or reasoning you used to answer Question 7.

**7.** The correct answer is: **b. The frequency would increase because individuals with the genes for more molecules would leave more offspring.**
**8. Reasoning:**
- Ultraviolet (UV) light can damage cells and lead to mutations, which can negatively impact an individual’s health and survival chances.
- Molecules that provide protection against UV light can mitigate this damage, thus increasing an individual’s fitness (their ability to survive and reproduce).
- If some individuals in a population produce more of these protective molecules due to specific genes, they would have a higher chance of surviving UV exposure, leading to a greater likelihood of leaving behind more offspring.
- Over generations, natural selection would favor individuals with these beneficial genes, leading to an increase in the frequency of these protective genes in the population.
- This process is consistent with the principle of natural selection, where advantageous traits become more common in a population over time.

**7.** The correct answer is: **b. The frequency would increase because individuals with the genes for more molecules would leave more offspring.**
**8. Reasoning:**
- UV light causes cell damage, which can reduce survival and reproduction.
- Genes that produce more protective molecules help individuals survive UV exposure.
- Individuals with these beneficial genes are more likely to survive and reproduce, increasing the frequency of these genes in the population over time.

**7.** The correct answer is: **b. The frequency would increase because individuals with the genes for more molecules would leave more offspring.**
**8. Reasoning:**
- UV light can hurt our cells and make it harder for us to survive and have babies.
- Some people can make special molecules that protect their cells from UV damage.
- Those who can make more of these protective molecules will stay healthier and have more babies.
- Because of this, over time, more and more people in the population will have the genes for making these useful molecules.

Of course! Here you go:
**7.** The correct answer is: **b. The frequency would increase because individuals with the genes for more molecules would leave more offspring.**
**8. Reasoning:**
- UV light can damage cells and hurt survival.
- Some people can make special molecules that protect their cells from damage.
- Those who make more of these molecules will be healthier and have more babies.
- So, over time, more people will have the genes to make these protective molecules.
