Answer:D
Explanation:
Because The genetic code by which DNA stores the genetic information. The functional segments of DNA which code for the transfer of genetic information are called genes
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
Answer:
swell
Explanation:
the cell will swell and become turgid as more water will be absorbed into said cell. this process is called osmosis, where water passes through a partially permeable membrane.

Hypertension (high blood pressure) has negative effects on health because people with this condition have a higher risk for heart disease and other medical problems than people with normal blood pressure.
If left untreated , hypertension can lead to :
1. heart attack
2. Stroke
3. enlarged heart
4. Kidney damage.
Once the kidneys are damaged, homeostasis in the body is severely impaired because the body no longer has the ability to clear waste products, which when they accumulate tend to poison the body leading to such conditions as uremia.
