The answer is; B
This type of inhibitors does not bind the active site of the enzyme hence does not compete with the substrate (hence its name non-competitive inhibitors). They bind the enzyme at another site and change its conformation. The substrate may still be able to bind the active site but the efficiency of catalysis can be drastically reduced threatening life. This type of inhibition cannot be cured by increasing substrate levels.
C the correct answer is c because our body produces carbon dioxide and brings in oxygen
The genes in a population give forth the genetic variability across a population (genotypes). In addition, occasional mutations of these genes in a population increase this genetic variability. Hovever, natural selection only favours reproduction of individuals with genes that are favourable in the environment/habitat. Therefore, natural selection has no foresight but is rather pegged on being an ‘opportunistic’ process.

Answer:
Flu vaccinations are fundamental as they reduce the risk of flu illness by over 50%.
Explanation:
Flu vaccinations <u>reduce the risk of flu illness by over 50%</u>. This makes this process extremely important and fundamental for all human beings as they <u>not only protect the person who gets the vaccine, but it also contributes to the prevention of spreading to other people</u>, especially children and older adults who possess a greater risk of developing flu complications.
<u>The antibodies that are produced by the vaccine prevent the flu virus from attaching to a healthy cell</u>. However, if a person has not been vaccinated, <u>the virus will attack the healthy cells</u> because there is an absence of antibodies that prevent this process.
