Explanation:
In parasitism, one of the organism, the parasite lives in or on the other organism namely the host causing it harm and sometimes death.For example a tick that lives on dogs is a parasite.In this answer choice, the rat is the host whereas the tapeworm is the parasite.
Best of Luck!
Answer:
Polymer
Explanation:
Monomers can be linked together to form a polymer
Answer:
Option 3, Chromatids remain attached to one another until anaphase
Explanation:
Centromere lies at the center, end or other points of the chromosome and joins the two sister chromatids. During cell division, the spindle fibers attaches at the centromere and detaches the chromosomes during the anaphase of the cell division to ensure that each daughter cell gets equal number of chromosomes at the end of mitosis. Centromere plays an essential role in the separation of chromosomes.
Hence, option 3 is correct
Answer:
Deletion and glycosylation.
Explanation:
Proteins is polymers of the alpha amino acids that are directly linked together through the peptide bond. Proteins plays an important role in the metabolic pathways as most enzymes are made of protein.
The same protein can exist in two different size. This might occur due to the deletion of the particular amino acids sequence in one organism and normal in other organisms. The glycosylation of the same protein at different position in the proteins may also leads to the difference in the protein size.
Thus, the correct answer is deletion and glycosylation.
Answer: Combining a basic API with citric acid to produce the citrate salt of the API.
Explanation:
Chemical modifications refers to the processes that involve changes in the general composition of drugs to produce another entity with different chemical properties.
From the answer, Basic API combine with citric acid to produce the citrate salt of API which have different chemical properties from the reactants.
