<u>Question</u>:
A substance that yields a cation plus the hydroxyl ion in water is a(n)
A) salt
B) acid
C) base
<u>Answer</u>:
A substance that yields a cation plus the hydroxyl ion in water is a(n) base.
<u>Explanation</u>:
Base is a substance that "donates electrons, accept protons, or releases hydroxide (OH-) ions" in aqueous solution .When a base is dissolved in water, it dissociates to give hydroxyl ions. Hydroxyl ion which is a negatively charged molecule and having one oxygen bonded to one hydrogen. In case of the base particles, when comes in contact with water becomes slippery as well as changes its colour. For bases, the pH value ranges from 8-14

Answer:
The earliest oxygen-producing life forms were Cyanobacteria. Besides Cyanobacteria, these tiny organisms have another name known as blue-green algae
Explanation:Some scientists think that 2.4 billion years ago is when organisms called cyanobacteria first evolved, which could perform oxygen-producing (oxygenic) photosynthesis. Other scientist think that cyanobacteria evolved long before 2.4 billion years ago but something prevented oxygen from accumulating in the air
Answer:
The primary means for transmitting messages between the brain and the rest of the body is the <u>spinal cord</u>.
Explanation:
The spinal cord is the main pathway of the nervous system. The impulses are transmitted to the brain through bundles of ascending nerve fibers, while the descending fibers transmit impulses in the opposite direction. Signals are transported to and from different parts of the body along the fibers of the pair of spinal nerves, which form intersections with the spinal cord through their dorsal and ventral roots; the sensory and motor fibers converge in the gray matter of the medulla.
