Hope that helps, Good luck! (:
Answer:
The correct answer is a. energy can be extracted in usable amounts.
Explanation:
Through the process of respiration, glucose is converted into carbon dioxide and water. This oxidation of glucose helps in the production of energy in usable amount which is used by the cell for their metabolic processes.
First, the glucose is partially oxidized to pyruvic acid then pyruvic acid is converted into acetyl Co-A which is used in the citric acid cycle to generate NADH, FADH₂, and ATP. Then the NADH, FADH₂ is used to provide electrons that helps in the generation of ATP through oxidative phosphorylation.
This ATP molecule has a high energy phosphate bond from which energy can be extracted in usable amounts. Therefore the correct answer is a. energy can be extracted in usable amounts.

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>
