Answer:
: A decrease in pH is too acidic compared to optimum pH for amylase activity.
<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:
The correct answer will be option-C.
Explanation:
The evolution of human species in which one species transformed into another species evolves by a mechanism known as anagenesis.
Anagenesis is the mechanism of evolution which transform one species into a different species within a lineage. This process is slow and takes time to form species, therefore, is also known as gradualism or phyletic transformation.
The<em> Homo sapiens</em> evolved from<em> Homo erectus </em>where<em> Homo sapiens </em>overwrites the ancestral species and caused the species to become extinct.
Thus, Option-C is the correct answer.
Answer:
Guard cells
Explanation:
Guard cells are the cells that are found around the openings of the stomata, their functions is that they regulate the opening and closing of the stomata. These cells are always fill with latex which is of high percentage of water, therefore when the intake of water is low, the functionality of the cells will be affected.
And it must be noted that, the stomata is very important in the exchange of gases, that is a process where oxygen is released and carbon dioxide is absorbed. Therefore when the cells are affected, the gas exchange will also be effected.
