Most likely due to the fact protists or protozoas causes diseases such as malaria and some are parasitic. And the major problem is they're microscopic making them a misfit for us and other organisms.
Polar bodies serve to eliminate one half of the diploid chromosome set in meiotic division in the egg, leaving behind a haploid cell. That means that 23 pairs (46) of chromosomes are going to be separated equally, 23 for the polar body and 23 for the egg cell. In case of trisomy 18, the division is not equal. Instead, the egg cell receives 23 +1 chromosomes and the polar body receives 23 - 1= 22 chromosomes.
That chromosome that was misplaced is the chromosome 18.

Answer:
The correct answer will be option-C.
Explanation:
Light-dependent reactions are the reaction of photosynthesis which takes place in the presence of light.
During light reaction, ATP and NADPH intermediates are produced which are utilized during the light-independent reaction. The main reactions that take place during light reactions are photolysis of water and ATP synthesis due to the electron transport chain.
Electron transport chain generates electrochemical gradient across the thylakoid membrane sue to the accumulation of protons in the thylakoid lumen and fewer protons in the stroma of the chloroplast.
This causes the osmotic movement of protons down their concentration gradient through ATP synthase. The movement if hydrogen ions take place from thylakoid lumen to stroma forming ATP molecules.
Thus, Option-C is the correct answer.
changing of stored chemical energy in food molecules to a form usable by organisms.
Explanation:
Cellular respiration involves the changing of chemical energy in food molecules to a form usable by organisms.
During the process of cellular respiration, oxygen combines with food materials in form of glucose to release useful energy needed for life to function.
Respiration can be pictured as the reverse process of photosynthesis in which chemical energy is produced.
In respiration, energy is released from the food materials.
