Answer:
All plant and animal organisms that float or move to a limited extent in water, carried by currents and waves are called plankton.
Explanation:
Jellyfish are on the border of plankton and nekton. They are made of gelatinous tissue in which water makes up 98% of the body's composition. Simple anatomy, they have a single-opening digestive tract and a reticular nervous system.

Im 90% shure its wethering but please don´t hate me if im wrong
Explanation:
The purpose of mitosis is cell regeneration, growth, and asexual reproduction,while the purpose of meiosis is the production of gametes for sexual reproduction. Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new daughter cells. The nuclei resulting from a mitotic division are genetically identical to the original nucleus. They have the same number of sets of chromosomes, one set in the case of haploid cells and two sets in the case of diploid cells. In most plants and all animal species, it is typically diploid cells that undergo mitosis to form new diploid cells. In contrast, meiosis consists of two nuclear divisions resulting in four nuclei that are usually partitioned into four new haploid daughter cells. The nuclei resulting from meiosis are not genetically identical and they contain one chromosome set only. This is half the number of chromosome sets in the original cell, which is diploid.
Out of the choices given, the mechanisms that drives evolution is natural selection. The correct answer is B, natural selection.
Both chicken pox and shingles are caused by varicella zoster.
Explanation:
Shingles and chicken pox both occurs by the attack of the virus, varicella zoster.
Cause: - The chicken pox spreads through the infectious elements in a person’s cough, sneeze and breathing. The shingles occur when this virus gets reactivated.
Portal entry: - Chicken pox virus enters through the tract of respiration and shingles enter from a person who already have it.
Signs & Symptoms: - Pox includes- fever, blister like itchy rash and shingles include- blister rash which has a distribution that is like a band.
Incubation period: - Pox can stay for a minimum of 15 days approximately and shingles too last for few weeks.
Treatment and prevention: - Both include treatment of antiviral and both can be prevented by avoiding infected people and increasing body immunity etc.
