Albinism is a recessive trait. A man and woman who both have normal pigmentation have one child out of three who has albinism (without melanin pigmentation). The genotypes of this child's parents: (C) Both parents must be heterozygous.
Albinism is an autosomal and not a sex-linked recessive trait.
Only homozygous recessive (aa) offspring will be albino, both homozygous dominant (AA) and heterozygous dominant (Aa) offspring will possess the normal phenotype.
Since it is given that both the father and the mother have normal pigmentation, thus they must both have the genotype Aa.
From the Punnett square it can be observed that a cross between the parents would result in the creation of three offspring with the normal genotype (one with AA and two with Aa) and one offspring with the genotype aa (albino).

Answer:
In liver and muscle cells, epinephrine stimulates the release of glucose from glycogen by inhibiting glycogen synthesis and stimulating glycogen breakdown.

Answer:
C
Explanation:
Even when sharks and tigers are both meat eaters, the question is about similarities between tigers and crocodiles, so D is out. A is about crocodiles and sharks, so it's out also. B suits for sharks too, so it's out too. C is the most suitable answer, because both animals have four legs, which means that they belong to the group of quadrupede animals.
There are choices for this question namely:
a) Release trapped air in the lungs
b) Strengthen the diaphragm
c) Prevent collapse of the airways
d) Condition the inspiratory muscles
<span>e) Control the rate and depth of respirations

There are multiple correct answers. The correct answers are:
(1) Release trapped air in the lungs
(2) Prevent collapse of the airways
(3) Control the rate and depth of respirations
The breathing technique that the nurse teaches the patient is called "pursed-lip breathing" wherein the patient inhales through the nose and exhales slowly through his puckered lips. This is done to release trapped air in the lungs (as COPD causes a ball valve like obstruction wherein there is difficulty exhaling rather than inhaling), prevent collapse of airways (therefore preventing an impending respiratory distress syndrome), and control the rate and depth of respirations (to prevent tachypnea or bradypnea that can result to respiratory alkalosis or acidosis respectively).
