<span><span>Photoreceptors
are cells</span><span><span> <span>in
the retina</span></span><span> that
begin the process of seeing. The retina is the back part of the eye that
contains the cells that respond to light. These specialized cells are called photoreceptors. They
absorb and convert light into electrical signals. These signals are sent to
other cells in the retina and ultimately through the optic nerve</span></span><span> <span>to
the brain</span></span><span> where
they are processed into the images we see. The answer is true. Animals
with photoreceptors have good vision.</span></span>
If the producer were to disappear then all the other organisms will either go extinct, survival of the fittest, or have to adapt to the change.
Answer:
This nucleus then acquires <u><em>one </em></u>electron to become electrically neutral.
Explanation:
Fusion :It is nuclear reaction which two or more than smaller nuclei combines together to form heavy nuclear.
A neutron combines with proton in order to make heavy electron that is fusion reaction is taking place.

The overall charge in the nucleus will be +1.And in order to neutralize this positive charge the nucleus will acquire single electron to become electrically neutral.
This is called <span>hyperlipidemia!</span>
Action potential <span>is the electrical signal that typically moves from the cell body down the axon to the axon terminals.
There are other terms to refer to this, and those are <em>impulse </em>or <em>spike</em>. This is so because action potential is created when "the membrane </span><span>potential of a specific axon location rapidly rises and falls," according to its definition.</span>
