Answer:
The correct answer will be G/G ; P/p x g/g ; P/p
Explanation:
Let G be the dominant allele for stem color and g be the recessive allele for stem color. Let P be the dominant allele for leave shape and p be the recessive allele for leave shape.
A. To solve problems... I think let me know if it helps
Answer:
hydrogen and oxygen combine explosively in a single raction
Explanation:
The reason is Molecules of hydrogen react with oxygen violently to break the initial molecular bonds and form new one between the atoms of the two elements. The reaction results into an explosive release of energy and the production of water because the products of the reaction are at a lower energy level
Answer:
The correct answer is D. proliferation and differentiation.
Explanation:
Primary immune response occurs due to the first exposure of an antigen to the immune system. The primary immune response is generally delayed by many days because it takes time for B and T cells to become cloned and to proliferate and differentiate.
Then after several days of proliferation and differentiation of activated T and B cells, T cells become effector T cells and B cell becomes plasma cells which then eliminates the antigen. Memory B and T cells are also produced during this process which helps in generating a quick immune response during the second and subsequent exposure of that antigen.
So the correct answer is D. proliferation and differentiation.
all living things are composed of cells
cells are the basic units of structure and function in living things
all cells are produced from other cells
