Answer:
B. generating more nerve cells
Explanation:
Mitosis is the process whereby a cell divides into two genetically identical daughter cells. It is way through which living cells reproduce and multiply themselves.
Hence, a nerve cell that do not typically undergo mitosis will be incapable of replicating/multiplying itself, hence, unable to generate more nerve cells.
<span> In the process of photosynthesis, chlorophyll goes into a peculiar excited state which can survive for an unusually long time. Furthermore, the excitation energy can hope from chlorophyll molecule to chlorophyll molecule. In this way a large collection of chlorphyll molecules function as an "antenna" that collects many photons and funnels their energy down to a reaction center, where one particular chlorophyll will lose an electron.</span>
The use of artificial fertilizer has helped the tomato plant to grow faster and taller.
- Natural fertilizers such as plant and animal wastes are considered eco-friendly as they are not harmful to the environment. They add nutrients to the soil in a natural way and do not degrade the soil. But, their impact is slow and cannot fulfil all the lacking nutrients.
- On the other hand, artificial fertilisers are harmful to the environment as they degrade the soil
- Still, the farmers prefer artificial fertilizers over natural fertilizers. This is because they help the plant to grow faster and taller by fulfilling the requirement of all lacking nutrients.
Thus, tomato plants are grown faster and taller due to the use of artificial fertilizers. Artificial fertilizers have a greater impact than natural fertilizers and provide the soil with the required nutrients.

Answer:
lymphocytes
Explanation:
In immune system, there are three main group of cells that is the response of our defenses.
Neutrophils are one group responsible to be the first response, they travel all around our body trough the stream blood and can detect the first signals of infection.
Monocytes and macrophages, are another group of cells that can "eat" the bacteria or viruses and destroy them when they are inside our body.
The third group, the lymphocytes, are conformed by three group of cells, T - cells (that help to destroy infected or cancerous cells), B- cells (responsible to produce antibodies, so they are the ones that conformed our second barrier of defense) and the NK cells ( natural killers, the ones to control several types of cancer and microbial infections).
Hope this info is useful.
