Answer:
Common examples include carbon, sulfur, oxygen, iron, copper, aluminium. Elements are represented by symbols. Compounds are substances made from atoms of different elements joined by chemical bonds. They can only be separated by a chemical reaction.
Explanation:
Substances can be categorised as either elements or compounds. Both of these are made up of atoms, the only difference is an element is made of one type of atom whereas compounds are made of two or more different types of atoms.
Answer:
An important feature that B-cells must have in order to become plasma cells and synthesize antibodies is increased rough endoplasmic reticulum in order to have the surface area needed for antibody production (option A).
Explanation:
The transformation of B cells into plasma cells to produce antibodies is a well known function of lymphocytes related to the immune response. This leads to a series of structural transformations in order to performs their function.
The rough endoplasmic reticulum (RER) has the function of contributing to protein synthesis, in conjunction with the ribosomes that are attached to it and the information of the mRNA.
<em>One of the changes experienced by B cells in their transition to plasma cells is the availability of larger RERs, in preparation for antibody synthesis, formed mostly by proteins</em>.

The analysis of total microbial genomes in an environment is called metagenomics and the total microbial genomes in an environment (or the total microbial community itself) is called a microbiome.
<h3><u>
Explanation:</u></h3>
The study that is associated with the genetic materials that are obtained directly form the sample in an environment refers to the term Meta genomics or ecogenomics or community genomics. It can be considered as the process through which the meta genome is produced.
The genetic material of the microbes such as fungi, bacteria, viruses and protozoa refers to microbiome. These microbes lives inside the body of humans. The weight may range upto 5 pounds for these microbiomes. Micorbiomes are the total number of micro genomes that are present in the environment.
