Answer:
Red blood cells are the type of cells which are responsible for the transportation of oxygen and carbon in the body.
White blood cells are the type of cells which are responsible for the protection of body against pathogens such as bacteria and viruses etc
Platelets are those cells which helps in blood cloting after injury.
Plasma is a liquid medium in which nutrients, water and blood cells are present. Its main function is to transport nutrients to the body where it is required.

Explanation:
1. Through mitosis, Parental cell divide into two daughter cells with same number of chromosomes.
While meiosis produce 4 daughter cell from a single cell with half the number of chromosomes as compared to parental cell.
2.Meiosis have two cycles , i) meiosis I and ii) meiosis II.
3. In meiosis I, chromosomes first go replication and become double, then cell inter into meiosis I then into meiosis II and finally produce four haploid daughter cells. It is the first step (meiosis I) that generates genetic diversity. During prophase I of meiosis I (meiosis) homologous chromosomes pair and form synapses, a special step of meiosis, which is the main reason of causing diversity.
4. There is crossing over which produce genetic diversity between gametes.
Answer: weathering and erosion
Explanation:
Since chemical spills are very harmful to aquatic/land life for both plants and animals, plants probably wouldn't grow back and animals could be mutated or even killed, decreasing the population of that species. A volcano eruption, can be both good and bad, since a volcano can kill animals and plants, but ash from a volcano is extremely fertile, so plants can regrow, which in turn brings animals back so they can feed on those plants.
Answer:
17 = D
Explanation:
Crossing over occurs when two different genes are crossed together which is exactly what happened in this question :)
