Answer:
- Both release carbon into the atmosphere.
Explanation:
Diffusion is the process whereby gases move from an area of high pressure to low pressure. This includes- Internal respiration - this is the movement in the internal tissues between cells and capillaries, and - External respiration - when gas is exchanged between the alveoli and lung capillaries. Perfusion refers to the blood flow to tissues and organs. Alveoli are perfused by capillaries so the diffusion of oxygen and carbon dioxide can take place.
Answer:
it has to be B because it spreads and then gets worse
Explanation:
Answer:
The correct answer will be- zygote →cleavage→ morula→ blastula→ gastrula.
Explanation:
Human embryogenesis is the study of the formation of an embryo from the zygote formed after the fertilization of the sperm and egg cell.
The fertilization takes place in the ovarian duct in females which form a diploid zygote. The zygote starts the process of cleavage that is cell division and differentiation and leads to the formation of a 2 celled stage, 4 celled stages and later 16 celled stage. The 16 celled stage is known as morula which further undergoes cleavage and form blastula. The blastula now forms a gastrula with 3 layered distinction- the ectoderm, endoderm and mesoderm through gastrulation.
Thus, zygote →cleavage→ morula→ blastula→ gastrula is the correct answer.
