Pure water has a pH level of 7, which means it is neutral on the pH scale. If you want to increase the pH of water, you must add an alkaline substance to it. The pH scale ranges from 0 to 14, with anything above 7 being alkaline, and anything below 7 being acidic.

Answer:
Wakefulness and sleep.
Explanation:
Hypothalamus may be defined as the small region of the brain that maintains the homeostasis of the body. The hypothalamus is divided into anterior hypothalamus and posterior hypothalamus.
The anterior hypothalamus of the brain is involved in the sleep activity of the organisms and releases the hormones also. The posterior hypothalamus is involved in the wakefulness of the individual.
Thus, the correct answer is wakefulness and sleep.
Answer:
There is little to no sunlight in the aphotic zone.
Explanation:
The aphotic zone is the deepest part of a lake/ocean, so no light is able to penetrate into those depths. Without light, photosynthetic organisms will not be able to undergo photosynthesis and will therefore not be able to survive.
Answer:
Release or egress
Explanation:
Virus can reproduce only within a host cell, this cycle of infection begins with the <em>attachment</em>, where the virus attaches to a specific receptor site on the host cell, after this comes the<em> entry,</em> in the case of enveloped virus, the envelope can fuse directly with the cell membrane to enter the cell, they can also enter through endocytosis. After entering the cell the virus initiates a <em>replication and assembly </em>mechanism depending on its genome, finally, the last stage of viral replication is the <em>release or egress </em>of the new virions produced in the host organism, some viruses can be released when the host cell dies, but some can leave infected cells by budding through the membrane without directly killing the cell.
