Final answer:
The physical basis of life is protoplasm. Evolution in biology means that living things constantly change. The blood group that can receive both A+ and AB+ is AB+.
Step-by-step explanation:
Physical Basis of Life:
The physical basis of life is protoplasm. Protoplasm refers to the living material found within cells. It includes the cytoplasm and nucleus, which are responsible for various cellular functions. The cytoplasm is the fluid-filled region of the cell that contains organelles, while the nucleus houses the genetic material.
Definition of Evolution:
The term evolution in biology means that living things constantly change. Evolution refers to the process by which populations of organisms change over time through the accumulation of heritable variations. It involves mechanisms such as natural selection, genetic drift, and mutation. Evolutionary changes can result in the formation of new species.
Blood Groups that can Receive A+ and AB+:
The blood group that can receive both A+ and AB+ is AB+. A and B blood groups have specific antigens present on their red blood cells. AB+ is the universal recipient blood type because it lacks antibodies against the A and B antigens, allowing it to receive blood from donors with any blood type.
Definition of Analogous Organs:
Analogous organs are those that are functionally similar but structurally different. These organs have similar functions and perform similar tasks, but they have evolved separately in different organism groups. An example of analogous organs is the wings of birds and the wings of insects, which serve the same purpose of flying but have different structures.
