The answer is A
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
Answer:
The correct answer is: False.
Explanation:
- A Fishery collapse can be defined as the condition in which the composition of different species of fishes forming a food chain or a food web and located in a marine or aquatic community undergoes a drastic alteration.
- The alternation can be caused due to environmental or anthropological factors.
- A fishery collapse usually affects the larger fish population like sharks and tuna as their commercial and economic demand is higher.
- Excessive fishing cause the population of the large fishes to decline without affecting the small fish population.
- This is because the small fishes do not have high economic or commercial demand, hence they have very less probability of being angled or captured.
Answer:
The amount of solar radiation that reaches any one spot on the Earth's surface varies according to: Local weather. Because the Earth is round, the sun strikes the surface at different angles, ranging from 0° (just above the horizon) to 90° (directly overhead).

Answer:
The heat given off by Earth's core is circulated through mantle convection.
Explanation:
Heating materials usually causes them to <em>expand</em>; as they become hotter, they also become less dense. Convection describes the transfer of heat from hot areas of liquids and gases to cooler ones. This causes the heated, less dense material to rise and more dense material to fall, as it’s pulled by gravity. Super-heated metal forming Earth’s central core heats rock in the mantle; the hot and cool rock slowly rise and sink- this circulation process is called mantle convection.

</span>Mutation can be defined as the permanent alteration
in the nucleotide sequence of the genome of a virus, organisms or other genetic
materials. However, a change in single nucleotide that result to a codon that
code for different amino acid can be refers to as Missense mutation.
