(B) Student A has normal "bitter" taste buds; student B has defective "bitter" taste buds that result in lower sensitivity to bitterness
(C) Student A has a protein receptor capable of detecting a bitter molecule found in that substance, whereas student B lacks that particles protein receptor
(D) Student A has normal saliva, whereas student B's saliva is more alkaline than normal

Answer:

Student A has a protein receptor capable of detecting a bitter molecule found in that substance, whereas student B lacks that particles protein receptor

Explanation:

The sensory organs helps to respond to the change in the external and internal environment. The five main types of sense organs are eyes, ears, nose, skin and tongue.

Tongue contains different types of taste buds and taste receptors that helps to distinguish between the different types of food. The receptors are mainly responsible for the taste detection. The student B is unable to taste the bitter molecule because they lacks the receptor.

Thus, the correct answer is option (c)

Answer: D. Digestion increases as the volume of the enzyme increases.

Explanation:

Enzymes speed up reactions by reducing the activation time of a reaction. If there are more enzymes therefore, the reaction will move faster.

Pepsin is an enzyme that prefers acidic conditions so it can work with dilute HCL. It can also work in temperatures of 40 °C without getting denatured. As more Pepsin is added therefore, the reaction will move faster and digestion will increase.

Genetic drift simulation:
Airida [17]
Unlike natural selection, genetic drift does not depend on an allele's beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation.
