Answer: C. Chromosomes
When an egg and sperm cell
unite, fertilization follows. The chromosomes carry the genes that will be
transferred to the offspring. They have threadlike bodies that made up of DNA
and protein that carries hereditary information, which is used to help a cell
grow and reproduce.
Furthermore, humans have 46
chromosomes and 23 in each sex cell and they are found in the nucleus of a
cell.
Answer: D) cAMP
Explanation:
In the absence of glucose cell can make use of other sources of carbohydrates such as lactose. In E. Coli and other bacteria utilization of lactose depends on the availability of cAMP. Bacteria accumulate cAMP only when starved. When glucose is exhausted, cAMP is available in plenty.
cAMP is necessary for the gene expression because it binds catabolite repressor protein (CAP) to form CAP-cAMP complex. CAP is a lac repressor the binds to the operator site of the lac operon preventing RNAP From binding to the promoter.
RNA polymerase can bind to the promoter site only when CAP-cAMP formed
You can easily find the answer only by observing the words. Transferases are the enzymes that transfer molecules form on group to another.
Transferase molecules have the function, as mentioned above, of transfering molecules. Some noticeable examples of these tranfer can be observed in cells.

Answer:
All animals are heterotrophic and have cells with no cell wall.
Explanation:
Since animals don't perform photosynthesis or any other process to make food, and don't contain a cell wall, that is what makes them different. Protist can be both autotrophic and heterotrophic and some can contain a cell wall, but most of them don't have cell walls.
The answer would be D
