When stimulated by the binding of specific chemicals, the membranes of taste bud receptors and olfactory neurons?

Taste bud receptors if not stimulated are normally polarized. With the presence of the food, chemicals from the food bind with the cell protein which depolarized the cell membrane receptor. Depolarization will lead into the propagation of electric impulse. This will lead into the creation of sensory impulse. The larger number of the chemicals in the food will lead into a stronger impulse.

The answer is depolarization. Depolarization is the influx of cations, especially sodium ions, from the extracellular fluid into the neuron cell hence generation an electrical impulse along a neuron. The resting potential of neurons is -70mV. When depolarized, the electronegativity in the inside of the neuron cell reduces.

Albinism is an autosomal recessive disorder. Two parents with normal pigmentation have an albino child. What is the probability

Serhud [2]

Answer: 0.0351

Explanation:

For two normal parents to give birth to an albino child means that both parents are heterozygous for albinism (Aa). And therefore the possible genotype for any of their children be AA Aa Aa and aa.

This means 1/4 will be totally free from the albinism, 2/4 will be carriers like their parents and have normal pigmentation and 1/4 will be albino.

The probability of normal pigmentation is 3/4 and 1/4 for albino.

Therefore the probability that in 4 children two will be albinos and the other two will have normal pigmentation is 1/4 * 1/4 * 3/4 * 3/4 = 9/256 = 0.0351
