Explanation:
Cancer occurs in dividing cells only because genetic materials divide into two equal portions during division. This process may be interrupted by carcinogenes or mutagenes to make mutate cells and then render them as cancer cells. In the brain, the cells are differentiated and there is no chance to start division, then how can cancer be found in the brain.
Answer:
it is the thymus

this is where the t cells and b cells are made
Answer:
The correct answer will be option-D.
Explanation:
Photosynthesis proceeds in two stages: light-dependent and light-independent reaction.
The light-dependent begins when the chlorophyll pigment of the photosystem absorbs light energy. This absorption causes the excitation of the electrons provided by the chlorophyll molecule.
The excited electrons accepted by electron acceptor molecule from reaction center and a chain of electron flow begin called electron transport chain.
This transport of electrons creates a scarcity of electron in photosystem which causes splitting of the water molecule as a result of which oxygen gas is released.
Thus, option-D is the correct answer.
