A. Volcanic activity

You can approach this question in two ways:

One:
when volcanos erupt (called volcanic activity), they will expel enormous amounts of soot, rock, smoke, and other materials into the air. This material, if light enough, floats around in the atmosphere and can block the sun. The CO2 and other greenhouse gases produced can also contribute to global warming

Two:
Notice how volcanic activity is something that happens randomly and ‘rarely’. However, answers B, C, and D happen all the time. Earth is always spinning, it’s also always rotating around the sun. The sun also never stops moving: its main motion is from revolving around the Milky Way. Thus, it makes sense to choose the one random, rare event. This is because we only see long-lasting climate change occasionally, and thus it can’t be something ordinary like earths rotation.

denpristay [2]

Answer:

<em>The correct option is B) Missense mutation.</em>

Explanation:

A missense mutation can be described as a type of point mutation in which a mutation in a single nucleotide causes the codon to change and form a different type of amino acid. As in the above scenario, we can see that the code CAU coded for the amino acid, Histidine, before a point mutation occurred. After the point mutation, the codon was changed to UAU instead of CAU. UAU codes for the enzyme, tyrosine, instead of histidine.

The gland located at the top of the kidney is the ________ gland.
Elza [17]

Answer:

adrenal

Explanation:

The adrenal glands are two endocrine glands in the human body. They are located above the kidneys.  Members of the endocrine system, the adrenal glands are very important to the human body because they make hormones essential for their functioning.

These glands are also responsible for the production of hormones that act on the transformation of fat into glucose by the liver. An example of this hormone is glucocorticoid known as cortisol, which also acts on the degradation of triglycerides. These functions are also performed by the region of the adrenal cortex.

The adrenal glands also produce in the adrenal medulla two other important hormones: adrenaline (also known as epinephrine) and norepinephrine (also known as norepinephrine). These two hormones act on psychic and physical reactions generated by strong emotional situations (mainly related to emotional stress).
