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:
Animals and plants need nitrogen to build amino acids in proteins, which are the building blocks of life. Unlike oxygen, nitrogen cannot be absorbed directly from the air by animals and plants.
Explanation:
Well the red blood cells ( erythrocytes) contain the oxygen carrying pigment known as haemoglobin. Hence RBCs carry oxygen to every cell ion the body.
The white blood cells ( leukocytes) form the cell mediated defence system of the body, they kill microbes and foreign particles either by phagocytosis or lysozymic reactions.
The platelets (thrombocytes) help in the blood clotting process.
This is my comparism of tne blood components.
