A process called cellular differentiation occurs. Although every cell contains the same genetic material it doesn't express every single gene.

For example muscle cells don't secrete adrenaline even though they have the genetic code for it. There are many processes that revolve around gene activation and inactivation that are studied by a branch of genetics called "epigenetics". Some examples of processes that inactivate genes are methylations or acylations which represent the attachement of different functional groups to the nitrogenous bases.

Ugo [173]

Answer:

IgE

Explanation:

Immunoglobulins can be described as antibodies that are found in blood and other bodily fluids of humans and other vertebrate animals. And their major function is that they help identify and destroy foreign substances such as microbes such as bacteria and protozoan parasites.

They are known to be produced by produced by plasma cells (white blood cells).

Immunoglobulins are classified into five categories: IgA, IgD, IgE, IgG and IgM. And are distinguished by the type of heavy chain they contain. IgG molecules possess heavy chains known as γ-chains; IgMs have μ-chains; IgAs have α-chains; IgEs have ε-chains; and IgDs have δ-chains.

In this case, IgE is the immunoglobulin that attach to and sensitize mast cells and basophils.

What two characteristics do fungi lack that forced them to become decomposers
Artist 52 [7]
Fungi are decomposers, they obtain their food from dead organic matters. Fungi obtain their nutrient this way because they can not produce their own food. To produce their own food they need chloroplast in their cells to obtain energy from the sun. And they also need the ability to fix nitrogen which they will incorporate into the food they produce. Because they lack the ability to do this thing, they have to adapt to eating dead materials. <span />
