Answer:
Homologous structures
Explanation:
Homologous structures are structures (i.e skeletal elements) that come from the same common ancestor but they appear in the descendants of the ancestor with some modifications, normally due to different functions.
The wing of bats, flippers of whales or dolphins and the forelimbs of horses is a common example of homologous structures. Bats, whales and horses are vertebrates and all came from the same vertebrate common ancestor.
The common ancestor of these organisms had the bones that make up these structures, but through evolution those bones that make up the homologous structure were modified to serve different functions. They were modified for the flight in bats, for swimming in whales and for life on land in horses.
Answer:
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
Answer:
B
Explanation:
The spine of a human is S shaped as opposed to that of a chimpanzee, that is C shaped. In humans, this shape allows for the weight of the chest to rest upon the pelvis. Conversely, the C shaped spine of apes allows for the weight to be forward which is better for four-legged locomotion.
