Answer and Explanation:
Primates must have long, strong fingers capable of supporting their own body weight when they need to climb, the ability to climb trees and stereoscopic vision. These skills help primates not only to survive in the wild, but facilitate the obtaining of food, resistance to predators and reproduction, these characteristics being the most favorable to maintain the continuation of the active species and competitiveness among members of the species.
Helloyo!
Massive Star
They are typically greater then 8 molar masses. They typically have a quick main sequence phase, a short red supergiant phase and a death of a spectacular Cosmic event: Supernova. From there they can either become Neutron Stars or Black Holes
Medium-Sized Star
They usually have a Normal Main Sequence phase (Billions of years). From there they bevome Red Giants and expell their mass in a planetary nebula. From there they shrink and become white dwarfs first, then black dwarfs.
Hope it helps ya
...though astronomy is actually physics btw...
Answer/Explanation:
Pollution during the industrial revolution caused trees to become covered with soot, making them darker. This dark appearance meant that the peppered moth, which usually had a light colour, was clearly visible against the tree. This meant it was easier for predators to identify. As a result, their numbers decreased because they were an easier target.
However, there was also a rarer form of the moth, which was dark in colour. These were initially very rare. However, because of the change in the tree colour owing to the industrial revolution, these moths were better suited to the environment, as they were more camouflaged against the dark tree. This meant it was easier for them to avoid predators, and so they were more likely to survive to reproductive age and pass on the genes that produce the dark colour. This meant that the dark moths increased in number.
