When part of the mushroom is damaged by an insect larvae bite, it will release a chemical that is poisonous. The chemical prevents the larvae from maturing into an adult. Some individual mushrooms of this species produce stronger chemicals that are more effective.

Which of the following best describes the type of mushroom that is more likely to survive and reproduce?
A.
Mushrooms that have the trait of attracting more insect larvae are able to spread their offspring further.
B.
Mushrooms that have the trait of producing stronger poisonous chemical have less energy for growth.
C.
Mushrooms that have the trait of producing stronger poisonous chemicals are better able to deter predators.
D.
Mushrooms that have the trait of attracting more insect larvae can get more food and nutrients.

Answers

Answer:

The answer is C

Explanation:

The correct answer is that mushrooms that have the trait of producing stronger poisonous chemicals are better able to deter predators and are more likely to survive and reproduce, which is Option c.

What is a mushroom?

The ability of a mushroom to produce a poisonous chemical when damaged by an insect larva bite is a type of chemical defense mechanism that many organisms use to deter predators. This chemical defense mechanism helps the mushroom protect itself from further damage by deterring the insect larva from feeding on it or from maturing into an adult. Individual mushrooms of this species that produce stronger chemicals that are more effective will be better able to deter predators and are therefore more likely to survive and reproduce.

Hence, the correct answer is that mushrooms that have the trait of producing stronger poisonous chemicals are better able to deter predators and are more likely to survive and reproduce, which is Option c.

this is science, please put a short desrciption for each of the sun's layers. ​

Answers

Answer: The core is the only place where nuclear fusion reactions can happen. In this broad zone, heat from the core cools dramatically, from between seven million K to two million K. Convection continues to be efficient in transporting heat until layers are reached where the density is so low that radiation from the hot up-flowing gas can escape directly into space. The lowest layer of the sun's atmosphere is the photosphere. It is about 300 miles (500 kilometers) thick. This layer is where the sun's energy is released as light. At other times, light from the chromosphere is usually too weak to be seen against the brighter photosphere. The chromosphere may play a role in conducting heat from the interior of the sun to its outermost layer, the corona. The corona is the outer atmosphere of the Sun. It extends many thousands of kilometers (miles) above the visible "surface" of the Sun, gradually transforming into the solar wind that flows outward through our solar system.
