Answer:

They are bulb-like structures at the tip of the frontal lobe where the olfactory nerves begin. (Ans A)

Explanation:

Olfactory receptors which are also known as smell receptor, and present in the cell membrane of olfactory receptor neurons. They are the proteins which are capable of binding with odour molecules which play an important role in the sense of smell.

Each receptor of olfactory cell contains a single external process which extends to the surface which is found in the epithelium, and gives rise long, slender extensions know as cilia. Mucus of the nasal cavity covered the cilia, and facilitating the detection of odour molecules.

The pathway that the viruses would most likely follow on first entering the plant is D. PHLOEM.

The phloem, whose purpose is to transport food from the leaves to the plant, is used as the pathway to spread the virus throughout the plant. The manifestation of aphid transmitted virus is the yellowing, mottling, or curling of leaves and the stunted growth of the plant.

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2>

$\Large\textbf{ACTIVE AND PASSIVE IMMUNITY}$

Active Immunity, Immunity which is acquired by the own immune response of the body.

Passive Immunity, Immunity which is acquired and dependent upon the antibodies transported from another person or even an animal. A person's immune system does not acquire or make the antibodies itself. A newborn baby acquires passive immunity from its mother through the placenta.

x---------------------------------------------------x

<h2> </h2><h2> $\Huge\text{Vaccination:}$ </h2>

Vaccination is a artificial active immunity. Artificial because the antibodies are not acquired by any natural infection but it is injected into the healthy body of the person. It is Active immunity because the body does not get already made (from other animal) antibodies but it acts on the small amount of the pathogen which is injected in the body and acquires the antibodies itself. So the person acquires antibodies naturally acting on the antigen. Antigen is any foreign agent which triggers the immune system to produce antibodies against it. Vaccines contains antigen which is a harmless form of the bacteria or a virus that causes the disease you are being immunised against. The bacteria or virus are in small proportion and greatly weakened in the vaccine so they just trigger an immune response without causing any real damage. When Vaccine is injected in the body, the immune system starts to make antibodies of different forms against the antigen(Virus or bacteria in the vaccine). When the appropriate shape antibody reacts with the antigen and forms antibody-antigen complex which destroys the antigen. This means that type and shape of antibody is perfect to work against that antigen, then the immune system start forming only those kind of antibodies in great proportion and the Person gets immunised by the vaccine in a natural way.
