The circulatory system circulates blood around the body. The blood passes through the lungs, where it loses carbon dioxide and gains oxygen. All cells need oxygen to function and carbon dioxide is a form of waste produced in the cells. The digestive system breaks down food and absorbs.
No they do not have the same process but they are very close and work in function with each other
The Stroma is the colorless fluid surrounding the grana (or Granum) and enzymes in the process of photosynthesis is embeded in the stroma and also the thylakoid membranes
Thylakoids are the site of the light-dependent reactions of photosynthesis. Thylakoids<span> consist of a </span>thylakoid <span>membrane surrounding a </span>thylakoid<span> lumen. They normally stack up in stacks called Granum and the Stroma surrounds</span>
The correct answer is option 1, that is, there is an evolutionary link between the classes.
The study of one kind of proof of evolution is known as embryology, that is, the study of embryos. An embryo refers to an unborn young in its initial stages. Embryos of various distinct types of animals, that is, mammals, reptiles, birds, fishes, etc. seems very identical and it usually becomes tough to differentiate them apart.
Various traits of one kind of animal are observed in the embryo of another kind of animal. This illustrates that the animals are identical and that they are developed identically, signifying that they are associated, have common descendants and that they began the similar, slowly developing distinct traits, however, the fundamental plan for the beginning of the creature remains similar.

22. is past medical history i don't know 23
Explanation:
Answer:
John Stephen Jones states that in evolution it is necessary to have into account three factors: natural selection, mutation, and random variation.
Explanation:
These three mechanisms influence evolution and they are responsible for generating phenotypic diversity that is observed in humans.
