Answer:

homeostasis

Explanation:

Living beings maintain the constant environment of the body. It is called homeostasis. Homeostasis is the maintenance of a relatively stable internal environment of the body. It is the result of all of the body’s regulatory processes.

For example, the blood glucose level is normally maintained between 70 and 110 milligrams of glucose per 100 ml of the blood. A rise of blood glucose level is counteracted by increased secretion of the hormone insulin from the pancreatic cells. Therefore, cells and higher levels such as organs and organ systems, contribute to maintaining homeostasis.

If there are 10 chromosomes in a particular cell at the start of prophase how many will be present in the same cell at the end o
Ilia_Sergeevich [38]

Answer:

20 chromosomes

Explanation:

Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.

In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome.

Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.

Answer:

Variation can be acted on by natural selection.

Explanation:

Variation are the difference that exist in the organism in terms of the body size and can be acted upon by natural selection.

Natural selection could act on the owl body size, favor the selection of owl with small body size especially when resources available are limited and can only sustain small number of individuals leading to availability of owl with small body size in such area and a gradual reduction in the number of owl with large body size.
