B) The mutation is beneficial and allows those who have it to reproduce more than average.
If the mutation is beneficial, it will become common in a population since the individual(s) that have this beneficial mutation will survive longer to produce more offspring that have this mutation. These offspring will also live longer and spread this mutation through the gene pool through reproduction.
Hope this helps :)
A hormone imbalance may occur if this feedback system has trouble keeping the right level of hormones in the bloodstream, or if your body doesn't clear them out of the bloodstream properly.
<span><span>The ER assembles proteins, and the golgi body modifies and packages them.
</span>ER Golgi apparatus, because it packages proteins received from the ER cytoplasm </span>
<span>The Golgi body are the ones that slightly alter, organize and prepare so-called parcels to be delivered for all the organelles in the cell. They receive these packages mainly in the rough endoplasmic reticulum. These packages that set out by Golgi body are macromolecules that used and synthesized by cells in many operations. If ER is absent then it would only mean that Golgi body would have no use other than simply lysosomes but these macromolecules plays a dynamic role in many organelles –nutrients, ATP and cell metabolism. It'll have a ripple effect if ER is absent in the cell.<span>

A. Mitosis is the correct answer.
DNA replication occurs in the two major types of cell division: mitosis and meiosis.
Mitosis is the splitting of a normal cell into two daughter cells and involves complete replication of the cells DNA to produce two identical copies. Meiosis is a specialised and more complex two-stage form of cellular division related to sex cells and involves DNA replication followed by an exchange of DNA material within/between the chromosomes to mix genes from both parents and produce daughter cells with half the number of chromosomes as the original parent cell. Animal sperms and eggs are examples of cells produced by meiosis and contain half the number of chromosomes as normal cells. When combined during fertilization the egg and sperm produce a cell with the full compliment of chromosomes.
Cytokinesis is a part of the cellular life cycle that is related specifically to the division of the cytoplasm (basically the "soup" of material inside the cell). It is part of the cellular division process but not specifically related to nuclear division (i.e. DNA replication).
Transcription relates to the production of RNA from DNA which is then used for protein synthesis. DNA is not replicated during the transcription process, rather, this is a separate process critical for the production of proteins by the cell.
The agent that kills bacteria is called bactericidal. Bactericidal agents act directly by destroying the present bacteria. It is also different from bacteriostatic, because bacteriostatic means the inhibition of the spread and growth of bacteria only.
