The answer is C because if you put coral reefs in more places more species of fish will come in hiding it
The number of connections among species
The answer is; producing a unique antibody from all other B cells by genomic rearrangement.
An isolated B cell produces monoclonal antibodies (also called Immunoglobulins). Different B cell types produce different types of antibodies (hence the serum of an animal has polyclonal antibodies). Memory B cells are developed when a particular infection is eradicated by the immune system. These B cells proliferate when the infection returns by producing the same antibodies that were effective against the foreign entity.
Answer:
when G1/S cyclin-CDK is activated. Expression of G1/S cyclins is regulated by E2F proteins
Explanation:
I've found this on Google
Commitment to cell division occurs at Start when G1/S cyclin-CDK is activated. Expression of G1/S cyclins is regulated by E2F proteins in conjunction with pRB proteins.. Mitogens stimulated cell division by increasing the amount of G1 cyclins.
