You are operating a powerboat at night. Your red sidelight must be visible to boats approaching from which direction(s)?

I believe the answer is head-on and port (left). The side lights are usually visible to vessels approaching from the front or the side. The red light usually indicates a vessel's port (left) side while the green light indicates a vessel's starboard (right) side. These lights ensure that there is safety at night as the vessels navigate.

Answer:

Head-on and port (left).

Explanation:

The red sidelight is called so because this light is visible to another boat that is moving towards the powerboat either from the side or in the head on the direction.
Besides the red light, another side light that is present in the green light.
Both fo the side lights are visible to the boats coming from the head-on direction. Besides this, the red light is visible to the boat coming from the left side which is called the port side.

if you were to watch an individual neurotransmitter molecule just after it was released what would happen to it

Olenka [21]

Neurotransmitter leaves the presynaptic cell by exocytosis. It is released in the synaptic space, and moves to the postsynaptic membrane to meet its receptor. When binding occurs, it triggers a response in the new cell.

-----------------------------------------

Every neuron forms connections with another cell.

When a presynaptic cell sends information, a neurotransmitter is released.

After the exocytosis event, this chemical substance travels through the synaptic space forward to the other cell. Once there, it binds to its receptors in the postsynaptic membrane.

When the joining occurs, the receptor acquires a channel shape. This change allows the ion transference that will make possible the modification of the action potential.

This binding produces the excitatory postsynaptic potential -depolarization-.

A new action potential initiates in the postsynaptic cell and spreads to the rest of the membrane, depolarizing it.

If the communication between cells needs to stop, the neurotransmitter will be taken out from the synaptic space <em>instead of binding to its receptor. </em>

There are two mechanisms by which the neurotransmitter can be eliminated: by deactivation or reuptake.

1. What might cause an increase or decrease of carbon dioxide in a given location such as in the atmosphere or buried under grou

AVprozaik [17]

1. The carbon-dioxide increases in atmosphere by fossil-fuels, decaying-dead, automobiles etc. and when animals or plant die they get buried and carbon content increases under the ground.

2. Greenhouse gas are those gases which trap heat in the atmosphere and maintain the temperature of the earth.

3. Diamond and graphite are solid forms of carbon.

4. Dry ice is the carbon as liquid.

5. Autotrophs make simple sugar glucose via photosynthesis and this sugar is used by heterotrophs as a substrate for respiration in the presence of oxygen.

Explanation:

When the fuels from automobiles, fossil-fuel, dead decaying organism release carbon in the atmosphere, the increase in carbon dioxide is the cause of global warming.

Greenhouse gases absorb the infrared radiations from the earth's surface and reradiate it back to the atmosphere. In short greenhouse gases allow sun's rays to pass through and maintain the earth's temperature otherwise the earth will become too cold to sustain lives.
