According to study island, "<span>results in many different types of organisms with different characteristics from their ancestors". There are few variations between parents and their offspring which assembles over time. This process authorizes species to be able to adapt and survive in changing environmental conditions. Additionally, it causes species to evolve nicely. </span>
Answer:
Compensatory hypertrophy is an increase in size of an organ or tissue after the organs and tissues are either damaged, removed, or cease to function.
Explanation:
Hypertrophy is the term used to describe an increase in cell size. If the enough number of cells in some organ hypertrophy, the whole organ will also hypertrophy.
Compensatory hypertrophy is an increase in size of an organ or tissue after the organs and tissues are either damaged, removed, or cease to function. It can take place in a number of human organs and tissues such as the liver, the kidneys, the heart, the spleen, the lungs, the pancreas etc.
Answer:
Explanation:
Meiosis is a form of cell division that occurs in the sex cells of organisms. It ensures the reduction of a diploid cell to an haploid cell to allow for the formation of a diploid zygote after fertilization (contribution of both parents haploid sex cells to give a diploid zygote). Thus, this process is very essential and important.
The reduction is accomplished by 2 divisions after the duplication of chromosomes
- first division: separation of homologous pairs of chromosomes (this reduces the total in half)
- second division: separation of sister chromatids of a chromosome.
The rearrangement in meiosis occurs by crossing over/genetic recombination.
This is the exchange of genetic material between homologous pairs of chromosome bringing about a rearrangement and genetic variation
An example of a chromosomal abnormality that arises as a result of defects in this process is the Down Syndrome which is caused by a nondisjunction of the chromosomes 21 pair in a sex cell.
This condition produces offsprings that have some characteristic facial features, short stature etc
