How are thorns and spines related to drought resistance?

Biology
1 answer:
Tresset [83]2 years ago
7 0

Answer:

To survive in drought conditions, plants need to decrease transpiration to limit their water loss. Some plants that live in dry conditions have evolved to have smaller leaves and therefore fewer stomata. Extreme examples are plants with leaves that resemble spiky thorns or spines.

Darwin observed that organisms that were best able to survive and reproduce had adaptations that were...
11111nata11111 [884]

Answer:

A: Suited for their environment

Explanation:

You can automatically eliminate B and C, since they both say that animals with adaptations that won't work with their environment would have a higher survival rate. This doesn't make sense; adaptations that wouldn't suit an environment would actually lower the population's chances of reproduction and survival.
That leads us to A and D. However, A would be the correct answer. Organisms with adaptations that suited their environment would help them (since it would make the organism more compatible with their environment), rather than having no change at all.

Hope this helped!
