Explanation:
Every cell of the organism has the same DNA sequence and same genes. However, not all genes are expressed in every single cell at the same time. Only those genes necessary for a specialised function of a specialised cell are expressed in the specialised cell. For example, skin cells have some different proteins than nerve cells. Genes responsible for those "skin proteins" are activated in skin cells and are turned off in nerve cells.
Parasitism
Explanation:
This relationship in which the heartworms gets nutrient from the host and in the process, the host eventually dies from infestation is known as parasitism.
- The organism that houses the heartworm is called the host
- The heartworm in itself is called the parasite.
- Parasitism is a positive - negative relationship in which one organism feeds on the other and causes harm to it in the process.
- Plasmodium falciparum is the parasite of malaria in man.
- In commensalism, one organism depends on the other without causing harm to it. Example is cattle and egret.
- Mutualism is a positive - positive relationship in which both organism derives benefits from the other. Example is lichen.
