Answer:
II. meiosis
III. fertilization
IV. gametes
Explanation:
Gamete formation and fertilization are the processes performed by all the sexually reproducing organisms. Gametes are the cells that are formed in the male and female sexual organs of these organisms. Formation of gametes occurs by meiosis and therefore, the gametes of a diploid organism are always haploid.
Male and female gametes fuse during the process of fertilization and form the zygote which in turn divide repeatedly to produce an embryo. For instance, sperms and eggs are the male and female gametes that are formed in testes and ovaries of male and female human individuals respectively. The fusion of sperm and egg produces a zygote that finally develops into a young one.
Scientists are studying compounds in a newly discovered rainforest plant. The plant produces an unusual substance that local people say acts as an anesthetic. If another scientist tests the substance using iodine, the scientist testing for carbohydrates.
The existence of carbohydrates in leaves can be sampled by the Iodine test. When chlorophyll is removed from the leaf by boiling it in alcohol and then placing two drops of iodine solution it turns blue in color which indicates the presence of starch.
The iodine test is a test that is utilized to test for the existence of starch. The mixture of starch and iodine produces an extremely blue-black color.

Answer:
During exercise your cells need energy to function. in order to do so they harness it through ATP. In order to get ATP the cells convert it to ADP usually through aerobic respiration. Aerobic respiration requires oxygen to function and the cells will use up all their oxygen stores for it. Cells will get more oxygen when the exercise has been completed through the pulmonary system delivering oxygenated blood to the cells and taking away the used CO2 rich blood.
