Answer:
The correct answer will be option- A
Explanation:
Red drop effect is the effect observed by the light present in the spectrum of the wavelength of red light. The effect is observed with the decrease in the quantum yield of the oxygen formed per quantum of light when the wavelength of light exceeds 680 nm.
The decrease of quantum yield is observed due to the fact that the oxygen is formed by the breakdown of the water molecule during light-dependent reaction which is initiated by the PS II which begins the chain at 680nm.
If light exceeds the 680 nm then, PS II will remain inactive and thus will abrupt the dissociation of the water molecule and thus the formation of oxygen during the light-dependent phase.
Thus, option-A is the correct answer.
Platelets are fragments of large, multinucleate megakaryocytes.
An important function of platelets is to <span>transport clotting factors.
</span>Platelets form a plug to help prevent blood loss in situation in which blood vessel is damaged. They play a central role in the clotting cascade.
The number of electrons in the outermost shell determines essentially the type of chemical reactions that an atom participates in it is because these electrons are involved in chemical reactions as they can be donated, shared and thus rearranged by forming covalent bonds to produce new substances
Answer:
When the chemical energy in food is transferred to cells in the body, the energy can be transformed into energy used by the body to do many things like run, ride a bike, do the dishes, pump the heart, and keep the body warm.
Answer:
Bone marrow transplantation
Explanation:
Stem cells are special cells generated in bone marrow. This can changed into different types of cells. They are red blood cells It carries oxygen to the body cells
.White blood cells Resisting agents from infections
. Platelets it performs clotting of blood
Stem cell transplant involves in removing of damaged cells instead placed stem places from blood or bone marrow
