C and D can be immediately eliminated because the behavior and habits of an animal cannot be determined accurately through fossils. A would be hard to know unless additional things were studied.
B is left. Fossils can prove the existence of dinosaurs, and they can be used to determine their characteristics.
ANSWER-B-The existence and characteristics of extinct dinosaurs
Answer: There is two forces acting on that Apple .
1. The Gravitational Force which is the reason why the apple falling towards the center of earth.
2. And the second less powerful force called Air drag or friction which try to keep the apple stable but Because of the power of Gravitational force and the air is not that dense so it just don't affect the apple that much as the first force does so as usual apple fall down.
Explanation: Yw.
The inheritance of skin color genes is polygenic, meaning that many different genes are inherited and none are dominant, but rather they all work together to create a special blend of genes that you have. This is also influenced by environmental factors such as exposure to sun and similar.
Human skin color is a polygenic trait, which means that multiple gene loci are involved in its expression. It has been shown that there more than 350 genetic loci involved in determining skin color. Because of that, there is the enormous number of possible genotypes for the skin color and as a result, the phenotypes vary from the darkest brown to the lightest hues. Different populations have different allele frequencies of genes for human skin color, and the combination of these allele variations brings about complex and continuous variation in skin coloration. Natural skin color can change due to exposure to sunlight (becomes darker) and that is the way it adapts to intense sunlight irradiation (protection against the UV exposure).
