Question

A population of comb jellies has members that show two distinct traits. One part of the population has male comb jellies that use a complex bioluminescence pattern to attract females. Another part of the population has male and female comb jellies that produce light in quick flashes. A new animal that preys on comb jellies enters the area.
​
Using Table 1, which statement describes the most probable change in the comb jelly population over time due to the introduction of the new predator?

A

Only comb jellies whose genes mutate to no longer glow will survive and pass on this trait.

B

The comb jellies that have the most complicated patterns will survive to pass on this trait.

C

The comb jellies that are able to glow in quick flashes will survive and pass on this trait.

D

The two types of comb jellies will have an  equal chance to survive and pass on their traits.

Answer 1

To determine the most probable change in the comb jelly population due to the introduction of a new predator, we need to consider the behavior of the predator and how it might interact with the two distinct traits of the comb jellies.

1. **Complex bioluminescence pattern:** This trait is used to attract females, which is beneficial for reproduction. However, it may also make the males more visible to predators.

2. **Quick flashes of light:** This trait might be less conspicuous or may serve as a distraction or confusion tactic, possibly providing better camouflage from predators.

Given this information, it is reasonable to assume that the quick flashes may provide an advantage in avoiding predation compared to more elaborate and visible patterns.

Therefore, the most probable change in the comb jelly population over time due to the introduction of the new predator would be that the comb jellies that are able to glow in quick flashes will survive and pass on this trait.

**The correct answer is: C** - "The comb jellies that are able to glow in quick flashes will survive and pass on this trait."
