<u>Answer:</u>
<em>The dissolved gases produce violent eruption as they escape.
</em>
<u>Explanation:</u>
Magma contains dissolved gases and these dissolved gases induce vapor <em>pressure on the magma.</em> The magma is able to remain in the dissolved state itself without erupting because this vapor pressure is less than the confining pressure of the <em>rock surrounding the magma. </em>
One the vapor pressure exceeds this confining pressure the dissolved gases begin to expand and<em> forms small gas bubbles</em>.
The <em>density of these gas bubbles</em> called vesicles is less than the density of magma and thus naturally tries to push out. When the gas bubbles escape the magma is also pushed out. Thus greater <em>amount of dissolved gases result in violent eruptions.

Answer:
system
Explanation:
An example of an organ system is the brain, spinal cord, and nerves working together.
<em>A system is a level of organization in living organisms in which body organs work together to perform similar functions. The organ system represents the highest level of body organization as opposed to organ, tissue, and cell level of organization.</em>
The cell is the smallest unit of organization of the body of living organisms. At the tissue level, cells aggregate together to perform similar functions while at the organ level, similar tissues come together to perform somewhat similar roles in the body of organisms.
<u>The brain, spinal cord, and nerves each represent an organ. When these work together in the body of organisms, the level of organization is described as organ systems or simply systems. </u>
You are right, it is B because, endocrine glands, as part of the endocrine system, they regulate and maintain a constant equilibrium in our bodies, known as homeostasis.
The reasons are:
- the blood is very low on nutrition
- the leech is not feeding itself regularly
The leech slows it metabolism a lot, so it can survive on very low nutrition. The blood is very low on nutrition, and it is the leech's food source, so the evolution made it preserve energy.
The leach doesn't have the opportunity to feed itself on regular basis, so it takes maximum advantage of any opportunity and consumes as much blood as possible so that it can survive long term when it will not have food at disposal.
The answer I would say is A.
The sun doesn’t make water
And electricity doesn’t come from the water cycle.
