Answer:
The correct answer will be option-C.
Explanation:
The process of translation in prokaryotes is complex process and proceeds in three steps: initiation, elongation and termination.
1. Ribosomal subunits: 50S (5S and 23S subunit) and 30S (16S and proteins).
2. Initiation factors: IF1, IF-2 and IF-3 which help in the formation of assembly.
3 GTP: guanosine triphosphate as a source of energy.
4. Charged tRNA: with N-formylmethionine is the first amino acid.
5. mRNA: the RNA to be translated.
Since the option contains both 50S and 16S components of ribosome thus, Option-C is the correct answer.
Answer: Reproduce, make energy, waste removal, react to changes
Explanation:
Cell walls are supporting structures that help the plant to have a fixed shape and protect it from injury,animal cells do not need to keep the structures because they have the skeletal system to protect the organs and cushion them against any external injuries.
Eating sharks will be of maximum risk.
Option D.
<h3><u>Explanation:</u></h3>
Biomagnification is a phenomenon where a toxin which is present in the environment is taken by smaller organisms and the concentration of toxins increase in concentration in higher tropic levels.
Suppose a toxin is present in sea water. It's taken by the small algae along with water which isn't metabolized by the algae, but stored in their body. Now these algae are consumed by small phytoplankton which consume a lot of algae, and the toxin present in their body, which again gets stored due to no metabolism. This even increases into smaller fishes, larger fishes and then into shark which has the maximum toxin concentration. So consumption of sharks will be of maximum health risk.
