Answer: 2) The cell grows to its mature size.
Explanation:
The G1 phase is often referred to as the growth phase, because this is the time in which a cell grows. During this phase, the cell synthesizes various enzymes and nutrients that are needed later on for DNA replication and cell division. ... The G1 phase is also when cells produce the most proteins.
All organisms arose from a single common ancestor.
An endosymbiont or endobiont is any organism that lives inside the frame or cells of some other organism most often, though no longer continually, in a mutualistic relationship.
Bacterial endosymbionts result in dramatic phenotypes in their arthropod hosts, including cytoplasmic incompatibility, feminization, parthenogenesis, male killing, parasitoid protection, and pathogen blocking.
Endosymbionts, such as Wolbachia, Rickettsia, and Cardinium, are a type of bacteria generally located in arthropod species inclusive of bugs, spiders, crustaceans, and mites, in addition to other invertebrates along with filarial nematodesEndosymbiosis is a form of symbiosis in which the symbiont lives in the body of its host and the symbiont in an endosymbiosis is known as an endosymbiont.

Answer:
Adaptive immune defense system consists of lymphocytes like B-lymphocytes and T- lymphocytes. B-lymphocytes provides humoral immunity while T- lymphocytes provide cell-mediated immunity to the body.
99% of lymphocytes circulate freely in the blood and lymph. B lymphocytes differentiate into plasma B cells and B memory cells when interact with antigen presented by T helper cells.
Then plasma cells secrete antibodies in the circulation which binds to extracellular antigens through antigen-binding site. Then the bounded antigen is recognized by receptors present on phagocytic cells. This receptor binds the Fc region of antigen bounded antibody and destroy the antigen by phagocytosis.
