Answer:
Black fur is more fit to survive in the environment than other colors of fur.
Explanation:
"Fitness", in terms of natural selection, is an organism's likelihood to survive in a given environment. Assuming that the increase in black fur is significant (Not attributable to pure chance), we can safely assume this is because Black Fur provides a competitive advantage in said environment over other colors of fur. There may be black terrain that allows them to blend into the environment and ovoid predators, or maybe it keeps them warmer if it is located in a cold region, thereby reducing the amount of resources they need to spend to stay warm.
Answer:
They have a gizzard to grind the food.
Explanation:
Birds cannot chew since they have no teeth. However, the beak allows them to split very large seeds or swallow them directly.
For their digestion they have a stomach where digestion enzymes are released. Also they have a gizzard that is an organ that grinds the food mechanically. This gizzard usually has small stones inside that were previously ingested and that helps to digest the food.
Explanation:
Evolution involves changing the hereditary characteristics of a population through generations. These traits are the expression of genes that are passed on to offspring during reproduction.
Answer:
They collect more information.
Explanation:
The heliocentric model has been modified with the help of telescopes and probes because telescopes and probes collect more accurate information about the solar system and planets. Due to information collected from these instruments, scientists are able to modify the heliocentric model more accurately. So we can conclude that with the help of telescopes and probes, the heliocentric model has been modified.
