I think the answer would be A , break the darkness period with a flash of light for some time so that the plants can bloom all year round.
Photosynthesis is the term for the process by which plants produce food and energy in the presence of some inorganic substances and solar energy.
<h3>What is the reason behind the above answer ?</h3>
The glass of water won't react when it's placed in the sun's rays.
One explanation for the response is: Water and ambient carbon will be the reactants in the experiment, which should produce glucose and oxygen in the presence of the sunbeam.
The true photosynthetic reaction also uses carbon dioxide and water as reactants, but chlorophyll is a plant pigment that is present during the reaction.

I think the correct answer from the choices listed above is the second option. The enzyme pepsin that is present in the stomach denature in the intestine due to the alkaline environment of the intestine. This is because pepsin has an optimum pH that is very low which is ideal for the acidic conditions of the stomach.
Answer:
Innate immunity is a non-specific immune system which provides defence against any pathogenic microorganism in early stages. It includes physical barrier such as skin, chemical barriers such as saliva, tears, et cetera, phagocytic cells such as macrophages, et cetera.
Acquired immune system is the one which develops after exposure to pathogen or antigen. It is highly specific in nature. It includes B-lymphocytes and T-lymphocytes. It includes the production of antibodies.
Vaccines are used to develop acquired immunity in people. The process is termed as vaccination or immunisation. Heat-killed or weakened pathogen or antigen is inserted into a person after which a person develops antibodies and memory cells against that pathogen or disease. So, the immune system acts more vigorously against that pathogen in secondary infection.
Thus, a person becomes immunised.
