Answer:
The correct answer is (b) epinephrine.
Explanation:
Epinephrine, also known as <em>Adrenaline</em>, is a hormone secreted by the medulla of the adrenal glands.
In medicine, epinephrine is used as a stimulant in cardiac arrest, as a vasoconstrictor in shock and as a bronchodilator and antispasmodic in bronchial asthma.
When epinephrine is inhaled in small doses, it causes short-term relief from the symptoms by widening the bronchial tubes allowing air to pass through.

Explanation:
<u>That a gene is common to all murderers in the population does not mean that murderers are not at fault for their crimes. </u>
<em>Having a gene that correlates with murder just gives one a genetic tendency but the environment and personal choice still have to influence the decision to commit the crime. In other words, one might have the genetic tendency to commit murder but still has to be environmentally enabled and the ability to choose to either do it or otherwise. Nature, nurture, and personal choice would have to synergistically work together for the phenotypic expression of such a gene. </em>
Answer:
Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose. Anaerobic processes yield only 2 ATP per glucose
Most humans (and vertebrates, in general) are genetically "programmed" to produce a brown skin pigment known as melanin. Albinism--the inability to produce melanin—is inherited in humans as an autosomal recessive trait. An individual with genotype AA or Aa will have normally pigmented skin, whereas an individual with genotype aa will produce no melanin. The albino's skin is very pale white, and the (highly vascularized) irises of the eyes appear red because no melanin obscures the red reflectance of blood.
The frequencies aa (Parental genotype male) and Aa (Parental genotype female, predict the frequencies of all genotypes and phenotypes expected to result from the cross of an albino male with a heterozygous female.
