Answer:
The answer to the question: These cells provide for the sense of smell:___, would be, A: Olfactory hair cells.
Explanation:
The sense of smell might be one of the most primitive, but also one of the most amazing senses of the human system. This sense initiates with the introduction of smells, in the form of chemical molecules dissolved in air, that once they come into contact with the mucus in the nostrils dissolve and reach a group of cells, on the olfactory epithelium known as the olfactory receptor neurons. These cells capture the chemicals and send neural signals towards the olfactory bulbs, where sensory neurons relay the messages towards the brain centers. In the brain, several steps take place in order to gain sense, comprehension and assimilation of the smell that has been captured.
Answer:

The exposure may be risk factor.
Explanation:
Given

Required
The odd ratio
First, we calculate the odds of exposure using:

For cases, we have:


For controls, we have:


So, the odds' ratio is:



Conclusion about the odds' ratio
The calculated ratio is greater than (and also far from) 1.
This implies that there is a greater exposure than the controls.
So, we can conclude that the exposure may be risk factor.

Organ rejection takes place when your body is subjected to a new organ which is a foreign object and attacks it.
<h3>What do you mean by Graft rejection?</h3>
Graft rejection may be defined as a process in which a transplant recipient's immune system attacks the transplanted organ or tissue.
Xenograft shows high rejection. This is because it involves the transplantation between genetically distinct members of different species.
The process of organ rejection is initiated by T cells which perform the role of the recognization of a transplanted organ.
If these T cells are activated, it may lead to organ rejection by undergoing clonal expansion, and differentiation of the effector cells, which together lead to the obliteration of the tissues.
Therefore, organ rejection takes place when your body is subjected to a new organ which is a foreign object, and attacks it.
