An obligatory parasite is a parasite which totally dependent on others for survival.
They are obligate in the sense that they cannot replicate outside of a host cell. To make a copy of itself, a virus must first enter a cell (intracellular), hijack the machinations of said cell (parasitic behavior) and then copy itself.
Acellular, also known as anucleate. Acellular refers to cells that lack a nucleus, while anucleate specifically means without a nucleus.
The habitat of a parasite is called a host. The host provides the environment for the parasite to live, feed, and reproduce.
The main difference between cellular and a cellular cementum is that cellular cementum contains cementocytes, while a cellular cementum does not contain any active cells and can not regenerate.
Yes, it is possible for a parasite to feed off of another parasite. This phenomenon is known as hyperparasitism. For example, there are parasitic wasps that can lay their eggs within other parasites, such as aphids, and their larvae then feed on the host parasite.
Viruses need living cells to produce more viruses. They are obliged to use living cells.
Tdap is an abbreviation for an immunization; it means tetanus/diphtheria/acellular pertussis.Tetanus, Diphtheria and Acellular PertussisTetanus, Diphtheria and Acellular Pertussis
No ,it is not .
They are not alive and therefore have no cells.
They are obligate in the sense that they cannot replicate outside of a host cell. To make a copy of itself, a virus must first enter a cell (intracellular), hijack the machinations of said cell (parasitic behavior) and then copy itself.

noncellular, acellular
None. Viruses are acellular. Many biologists do not consider viruses to be living things in part because they are acellular. Look at any phylogeny (tree of life). Viruses are not on them.
There was no statistical difference in mouse protective potency between these acellular or whole cell pertussis vaccines. 2. There were no differences in chemical ingredients between acellular and whole cell pertussis vaccines except for protein nitrogen content. The protein nitrogen content of whole cell vaccine was at least three times higher than that of the acellular product. 3. Anti-PT antibody productivity of the acellular vaccine was higher than that of the whole cell vaccine. 4. Anti-agglutinogen antibody productivity of the whole cell vaccine was higher than that of the acellular vaccine. 5. There was no pyrogenic activity with the acellular vaccine, but high pyrogenicity was seen with whole cell vaccine. 6. There was high body-weight decreasing toxicity in mice and guinea pigs by the whole cell vaccine. 7. The mice died when they received whole cell pertussis vaccine iv, but no deaths occurred in the mice which received acellular pertussis vaccine.
It is obligatory that we finish this assignment before class ends.
Another word for obligatory is "required" or "necessary".
