The correct answer is option C, that is, regulate water loss.
Guard cells refer to the cells enclosing each stomata. They assist in monitoring the rate of transpiration by closing and opening the stomata. The guard cells possess the tendency to monitor the closing and opening of stomata by changing shape. The shape of the guard cells modifies on the basis of the concentration of potassium ions and water found in the cells themselves.
The stomatal pores get closed when carbon dioxide is no longer needed for the process of photosynthesis. The guard cells swell when movement of water takes place inside these pores, and thus, the opening of stomatal pores occurs, and as water moves out, the guard cell closes. Thus, guard cells play an essential role in regulating water loss.

Explanation:
Answer:
In case, when an allosteric site undergoes certain modifications it will demonstrate some changes like change in affinity towards the inhibitor, however, how the changes take place is not known exactly because of less knowledge of the FX11 composition. Though it is for sure that the modification will decline the affinity and the FX11 will exhibit less efficacy in preventing the growth of C. parvum.
An inhibitor targets the allosteric site as the size and the functional groups present within the site matches with that of the inhibitor, and thus affinity is attained. However, when there is a change in structure, the affinity will also get influenced.
The gossypol and FX11 can be utilized as drugs for human beings as these substances prevent the process of lactic fermentation, and the pathway for lactic fermentation generally is less common in human cells. The parasite C. parvum is found within the digestive tract, and the process of anaerobic respiration usually does not take place in the organs present in the digestive tract. However, in specific cases, only the muscle tissue can go through anaerobic respiration like in the case of performing physical activity. It is also to be noted that the drug can even invade other tissues via blood, therefore, at the time of consuming drugs, there is a need to instruct the patients to prevent any kind of physical activity.
Answer:
Provide information about geography
Explanation:
<em>UAVs are otherwise known as unmanned aerial vehicles or drones. They are usually remotely controlled and monitored from a screen. They can be flown over a large expanse of land to obtain geographical information such as the topography of an area, the distance between two points, the height above sea level, and so on.</em>
<u>Except the UAVs are specially designed and equipped with extra features, they cannot be used to obtain information relating to soil nutrients, soil hydration, or information about plant health on a field. </u>
Hence, the correct answer would be option 1,
