Answer:

I will give you 5 of them :)

1.Flightless Birds

Birds such as ostriches, emus and penguins are unable to fly. However, this hasn't always been the case — each of these flightless birds has ancestors who easily flew. Over many generations, ostriches and emus evolved to have larger bodies and feet made for running on land, which left them without the ability (or need) to fly. The same goes for penguins, who traded typical wings for swim-friendly flippers over many thousands of generations.

2.Blue Moon Butterfly

The Blue Moon Butterfly on the Samoan islands was attacked by a parasite, which destroyed male embryos. This changed the balance of male and female but that was remedied within 10 generations. This is because the few male moths that were immune lived to breed.

3.Mexican Cavefish

Mexican cavefish once had eyes, but in the caves, eyes were no longer necessary. They have also lost their pigmentation because they no longer need camouflage from predators. This is an example of regressive evolution, the belief that "if you don't use it, you lose it" when it comes to traits.

4.Warrior Ants

These ants have a chemical signal that identifies their colony. Some ants learned to imitate this signal from another colony, so they can attack a colony and take over. The worker ants will not even realize there has been an invasion and continue to work.

5.Pesticide Resistant Insects

Whenever you use a pesticide, it kills the majority of an insect population. However, certain insects will experience a gene mutation to develop immunity to it and those insects will reproduce. This happens very quickly, within a few generations, since the generation length for insects is short.

Explanation:

The changes are the organism's adaptive traits and they arise as a result of natural selection. An example of adaptive evolution is the horse's teeth. Its teeth are one of the traits that made it fit for a grass diet. In contrast, genetic drift produces random changes in the frequency of traits in a population

When the sun impacts weather, an interaction with the __________ takes place.
Nadya [2.5K]

Answer:

Hydrosphere

Explanation:

When the sun impacts weather, an interaction with the hydrosphere takes place. The hydrosphere is the part of the earth that is enveloped by water. Water exists in three different forms on the earth based on diverse factors.

Weather is the atmospheric condition of a place over a short period of time.

The sun causes the warming of the earth surface which leads to evaporation of water vapor into the atmosphere.

This water in the atmosphere is forms rainfall, one of the elements of weather.

The sun causes an impact on weather by causing evaporation of water into the atmosphere.

This interaction takes place in the hydrosphere.
