Answer:
All of the above traits combined
Explanation:
Phylogeny is an evolutionary history of development of a certain species or taxonomic group.
The purpose of phylogenies is to represent evolutionary relationships among a group of organisms.
During the reconstruction of phylogenies. Systematists often use a variety of traits in order to produce a good estimate of a phylogeny.
The use of molecular traits, gross morphological traits, behavioral and biochemical traits combined can give a good estimate of a phylogeny.
It will completely stop the enzyme's activity when the denaturization is complete.
Answer:
C. Vaccination
Explanation:
vaccination is the administration of a vaccine to help the immune system develop protection from a disease. Vaccines contain a microorganism or virus in a weakened, live or killed state, or proteins or toxins from the organism.
The three situations in which ionic reactions go to completion is formation of a gas, a precipitate and a slightly ionized product.
<h3>What are ionic reactions?</h3>
It indicates the flow of electrons and, therefore, the bonds broken and formed in the course of the reaction. It is theoretical, it can be corroborated by experiments, but sometimes there is no consensus on the mechanism by which a certain reaction occurs.
Chemical reactions are the result of the transformation that occurs in substances, where atoms rearrange themselves, modifying their initial state. Thus, chemical compounds undergo changes generating new molecules. In turn, the atoms of the elements remain unchanged.

Answer:
Humoral immunity involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood.</u>
Explanation:
Humoral immunity is defined as the immunity which is mediated by several macromolecules presnet in the extracellular fluids such as antibodies, certain antimicrobial peptides, and complement proteins.
Humoral immunity allows to distinguishes two groups of foreign substances. it involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood. </u>
Humoral immunity begins when an antigens bind to B cells. Interleukins or helper T cells provides a secondary signal to the B cells that activates a B cell and allows B cell proliferation. which roduces produce plasma cells. The plasma cell then produces antibodies which are identical to the specific antigen. The antibodies are the released and circulate through the body, binding to antigens. B cells the further produces memory cellss for future immunity.
So, Humoral immunity involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood.</u>
