What effects genetic variation and environmental factors have on organisms

Biology
1 answer:
Irina-Kira [14]3 years ago
8 0

Answer:

Explanation:

Evolutionary psychology seeks to understand the adaptive, evolved nature of humans by considering the forces of natural selection that gave rise to it. Individual humans also exhibit maladaptation, however, and some of the variation in maladaptive conditions is heritable. An evolutionary perspective can shed light on these phenomena too. Recent work suggests that developmental imprecision importantly affects the fitness of organisms and some of the genetic influences have been identified. Both theory and evidence that developmental imprecision underlies human cognitive maladaptation has begun to accumulate, although the manner in which the developing brain is affected remains largely unknown.

Which of the following is a correct statement about the endocrine system?
Gnesinka [82]
<h3><u>Answer;</u></h3>

The adrenal glands sit on top of the kidneys and release adrenaline, which affects heart rate.

<h3><u>Explanation;</u></h3>
  • Adrenal glands are located at the top of each kidney. They produce hormones that help the body control blood sugar, burn protein and fat, react to stressors like a major illness or injury, and regulate blood pressure.
  • The Adrenal glands are made up of two regions; the adrenal cortex and the adrenal medulla. <em><u>The adrenal medulla produces hormones adrenaline also epinephrine and noradrenaline also norepinephrine. </u></em>
  • <em><u>Hormone adrenaline rapidly responds to stress by increasing your heart rate and rushing blood to the muscles and brain.</u></em>

What causes genetic variation to be preserved or eliminated and how does that effect evolution
AfilCa [17]

Answer:

Mutation. Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. ... Some mutations are unfavorable or harmful and are quickly eliminated from the population by natural selection.

Describe why drugs that interfere with the disassembly of a SNARE complex are capable of blocking neurotransmission.
Aleks [24]

The drugs that interfere with the disassembly of a SNARE complex are capable of blocking neurotransmission because the SNARE complex is responsible for the exocytotic release of neurotransmitters.

<h3>What is neurotransmission?</h3>

Neurotransmission is defined as the transfer of information as electrical impulses from one nerve cell to another.

The chemicals that helps in the neurotransmission are called the neurotransmitters.

The SNARE complex are a group of protein family that is responsible for the release of neuroticism from the neural vesicles.

Therefore, the drugs that interfere with the disassembly of a SNARE complex should be capable of blocking neurotransmission.
