The cells that are transformed into plasma cells with the influence of cytokines are T-Helper cells. It is a very important cell in our immune system and it is used to activate antibodies that could help destroy microbes and pathogens entering the body. They are commonly produced in the bone marrow.
Answer:
Renewable Energy Resources.
Explanation:
Unlike fossil fuels which cannot be recovered when destroyed, these sources of energy can be recovered by a means of recycling . Recycling here reduces solid wastes which is one of the causes of land pollution.
Hydroelectric schemes can only be built in mountain regions where rainfall and rivers are plentiful which involves upset of aquatic ecosystem. This poses a dangerous pollution problem though.
Wind generators and solar panels are not very efficient energy producers. However, future schemes for producing solar energy via solar satellites are promising.

Answer:
Explanation:
DNA polymerases are the enzymes that build DNA in cells. DNA polymerase also proofread their work to check for any error the process of which is called proof reading.
If the polymerase detects that an Incorrectly paired nucleotide has been added, it will remove (splicing) and replace the nucleotide with the correct one before it continues with DNA synthesis.
Mismatch repairing also corrects other errors that omit proofreading. They fix mismatched base pairs, replace some insertion and deleted base pair that can result into mutations.
When an error is corrected the rate of mutation is reduced this is because mutation results from error during the DNA formation process either through Insertion of a wrong nitrogenous base, or deletion leading to formation of an entirely new amino acid sequence that result into abnormal phenotype.
