Any change in allele frequencies in a gene pool is a mutation
When a parent cell splits into two daughter cells, it is mitotic cell division (Mitosis). So if the parent has four chromosomes and the daughter cells are identical, they will also each have four chromosomes. For example, we humans have 46 chromosomes, 26 of them from the mom and the dad.
Answer:Living organisms release energy gradually to prevent most of the energy from heat loss. The cells release the chemical energy present in food and it should be utilized gradually to prevent the energy loss in the form of heat and light.Most of the energy released by the body is through cellular respiration.The energy is produced by the continuous process that occurs in the body ,breakdown of food and energy production.If a huge amount of energy will be released from the body it will only be in the form of heat loss so to prevent the energy from lost in the form of heat living organism release energy gradually
Plants have cell walls, so cytokinesis cannot go on with a cleavage furrow, but instead, a cell plate forms across the cell in the location of the metaphase plate.
There is no distinct groove along the cell plate as the cell divides because of the rigid nature of the cell plate or new cell wall.
A plant cell divides differently from an animal cell which forms a clear cleavage furrow because it only has a flexible cell membrane and not a rigid cell wall like plants.
The cell plate in plant cells is formed by membrane bound vesicles which migrate to the center of the cell where the metaphase plate used to be and fuse together to form a cell plate.
