The question is incomplete as it does not have the options which are:
A) relay molecule
B) transducer
C) signal molecule
D) response molecule
Answer:
C) signal molecule
Explanation:
The transmission of signals in the neurons takes place in the form of electrical energy and chemical energy. The signals get transmitted in the form of electrical signals inside the neurons but when the signals have to be passed on to the next neuron on the pathway then the electrical signals get converted into the chemical signals.
The electrical signals cause the release of the chemical signals molecules called neurotransmitter from the synaptic vesicles in the presynaptic neuron and also opens the gated ion channels at the terminal.
The neurotransmitter thus acts as a signal molecule in the transmission of a signal through neurons.
Thus, C) signal molecule is the correct answer.
<span>Cilia, flagella, and centrioles. Cilia and flagella are projections from the outside of the cell. They are made up of microtubules and are covered by an extension of the plasma membrane. They are motile, meaning that they are mobile, and designed either to move the cell itself or to move substances over or around the cell.</span>
Living things have cells, can reproduce, maintain good metabolism, maintain homeostasis, react to their environment, and grow/develop

Answer:
Density is the mass per volume, so a simple example is if you have ever tried to mix water and oil. Oil is less dense than water, so it floats on top. A boat also floats for the same reason, Its average density is less that that of water (because of the air in the hull) so it can also float.
