Answer:
The physical space between the presynaptic and postsynaptic neurons is called the synaptic cleft
and the chemical that is released to signal across this space is called a neurotransmitter
Explanation:
A synapse is the junction between dendrites of two adjacent neurons. Its function is to allow the transmission of nerve impulses from neurone to neurone. Tn the presynaptic knob there are vesicles which contain a transmitter substance which is usually acetylcholine. The acetylcholine diffuses from the presynaptic membrane to the postsynaptic membrane.
Transport proteins require energy because they are pumping materials. Without energy, they won't function and we will have huge problems in our body.

Answer:
Hot metal.
Explanation:
Hot metal is the stimulus that allows nervous system and muscular system work together. When the person touch the hot metal, the sensory cells present on the skin sends signals to the central nervous system through sensory neurons. The central nervous system made a decision and order to the muscles of the hand to remove hand from the hot metal or body. These orders are send to the muscles through motor neurons. In this way, both nervous system and muscular system work together.
The correct answer is "<span>press firmly against the wound with a sterile dressing".
Pressing firmly against a bleeding wound, may counter the severe bleeding and may also stop the bleeding, since the pressure that causes blood to gush out, is given a counter pressure to stop. Using sterile dressing while doing this to an open wound may also prevent infection.</span>
