Answer:
Darwin’s findings based:
a. Organisms descended from a common ancestor
Explanation:
Darwin thought of evolution as "descent with modification," a process in which species change and give rise to new species over many generations. He proposed that the evolutionary history of life forms a branching tree with many levels, in which all species can be traced back to an ancient common ancestor.
Answer:
Grafting can be defined as a surgical procedure that involves the removal of skin from area of the body to another part of the body in the same person or another person.
It is done in case of burns or injury. Grafting can be classified into following types.
Autograft: The donor and the recipient are from the same individual.
Allograft can be defined implanting tissue or organ from another individual of same species.
Isograft can be defined as implanting tissue or organ from genetically identical individual.
Xenograft can be defined as implantation of tissue or organ from different species.
Answer: The plasma membrane is composed of a bilayer of phospholipids, with their hydrophobic, fatty acid tails in contact with each other. The landscape of the membrane is studded with proteins, some of which span the membrane. Some of these proteins serve to transport materials into or out of the cell. The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins. A phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group.

Explanation:
Primary succession is when a population arises from an environment that was previously entirely devoid of any living things.
Therefore, the number of living things would start at 0. Once a pioneer species colonizes the area, it makes the soil more fertile. This makes it a more suitable environment for other species to grow. Over time, the number of species increases as the community becomes more complex, until it reaches its peak and plateaus at its final composition, which is called the climax community.
