Which Parts of the Water Cycle involve absorption of energy from the sun?
Ilia_Sergeevich [38]
<span>Evaporation and transpiration.
</span>
The evaporation process uses the sun radiation or sun’s thermal energy for vaporization of a water from the land or soil to be water vapor then in the air. Transpiration on the other hand is the same with evaporation that involves water molecules to be vaporized into the air but it is located in the stoma of the plants.

Over successive generations, moths develop spots that resemble eyes on their wings that scare off predators. this characteristic
Sati [7]
In this example of evolutionary development, we can see a selective advantage.
Developing of new characteristics, in this case, the spots on moth's wings is a part of the process of adaptation of organisms to their environment.
The new characteristics are acquired through mutations and natural selection filters the ones that are the most beneficial for the holder.
For example, a  mutation which results in moths having shorter wings is disadvantageous, because it makes the individual who possesses it less likely to survive and reproduce.
On the other hand, developing of spots that resemble eyes can be advantageous, since it enables the holder of the trait to be more successful and more likely to leave offspring.

<h3>When chiasmata can first be seen in cells using a microscope?</h3>

Recombination can occur at any two chromatids within this tetrad structure.

Crossovers between homologous chromatids can be visualized in structures known as chiasmata, which appear late in prophase I.

Thus, option "C" is correct, Prophase I.
