What is the elevation of point B
Alika [10]

Answer: c. Point B has an elevation less than 2750 feet.

Explanation:

The lines drawn on the map are known as contour lines and they are used to measure elevation. Point B is on a river and rivers are only able to flow at a lower elevation than the area around them.

Point B is therefore lower than the area around it and as the closest contour line to it puts the area at an elevation of 2,750 feet, that must mean that Point B is lower than 2,750 feet.

svet-max [94.6K]

Answer:

<em>B and C.</em>

Explanation:

The epidemiological triangle is an illustration of interaction among suitable hosts, disease agents, and the environment that drives successful outbreak of diseases.

In order to successfully tackle or reduce the incidence of a disease, the triangle has to be broken.

<em>In the case of malaria which is caused by plasmodium but spread through the female anopheles mosquito, one way of breaking the epidemiological triangle is to eliminate female anopheles mosquito in the environment using any possible means. This will stop the spread of the parasite and hence, the disease.</em>

<em>Another way to reduce/prevent malaria is to prevent the vector, female anopheles mosquito from getting to the host, the human populace. This can also be achieved by several possible means.</em>

Relocating the entire village to a neighbouring village might not break the epidemiological triangle as long as female anopheles mosquito still abounds. In the same vein, antibacterial drugs will not help to treat malaria. However, instructing residents on personal protective measures and controlling the vector through chemical larvicides will go a long way in breaking the triangle and reducing the incidence on the malaria disease.

<em>The correct options is B and C.</em>

Why is it so important to properly don and remove personal protective equipment?
artcher [175]
<span>Personal protective equipment is only helpful if regulations for using it are followed carefully. If it is not worn and used properly, then it will not function properly and it might not provide the protection that is needed in the situation. For example, a helmet is only effective if it is fitted properly and snugly on the head. Otherwise it could fall off in an accident and be rendered useless.</span>
