The answer to this question would be endocytosis.
Endocytosis a process to bring outside material into cell. The word "endo" itself mean "inside". This material could be source of energy or microbes that need to be killed. It's opposite would be exocytosis. The word "exo" itself mean "outside".
Both of them is pretty similar because they use vesicle to transport the things that need to be moved.
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

There are 6 type of simple machines, one of which is lever. Hammer is an example of lever. Levers are rigid bars that are pivoted at one point called a fulcrum, that is your hand. This is also the point where you apply force that is being maximized along its length to make it easier to pin down the nail.
They are all zones found in freshwater systems. Freshwater biological
