What is weathering and erosion

Biology
2 answers:
Liula [17]4 years ago

Weathering is when rocks, soil, or other minerals are broken down.

Erosion is the process through which weathered rock is moved from one place to another. Erosion can dissolve rock by weakening the rock or by turning it into other fragments that are very small.

Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock. One example is called frost action or frost shattering.

Schach [20]

Answer:

The mutated cell will have 25 chromosomes.

Explanation:

Meiosis is a cell division process in sexual reproduction which involves two successive divisions of a cell having a diploid (2n) number of chromosomes into four daughter cells having a haploid (1n) number of chromosomes.

Meiosis consists of two successive nuclear divisions, meiosis I and meiosis II. Each division consists of these stages: prophase, metaphase, anaphase, and telophase.

Anaphase consists of anaphase I and II. During anaphase II, the centromeres linking the two pairs of chromosomes which are called chromatids separate, and the sister chromatids move toward the opposite poles of the cell and are now called chromosomes.

Therefore in the chimpanzee having 48 chromosomes, after underoing meiosis, each daughter cell will have 24 chromosomes. If there is a case of non-separation of one chromosome, the cell will have 1n + 1 chromosomes i.e. 24 + 1 = 25 chromosomes.
