Which layer of the sun is shown extending into space in the picture above?
Westkost [7]

The Sun's outer gases extend far beyond the photosphere (Figure 6). Because they are transparent to most visible radiation and emit only a small amount of light, these outer layers are difficult to observe. The region of the Sun's atmosphere that lies immediately above the photosphere is called the chromosphere.

Which force is responsible for waves and surface currents?
Fynjy0 [20]
Ocean tides are caused by the gravitation of the Moon. Currents can be formed by the flow of tidal water around the continental plates, or by a difference in water temperature between large ocean areas. Surface waves are caused by the wind. Abnormal waves can be created by the tectonic movement of plates around and under the ocean floor (tsunamis). So as you can see, the answer is (C) Gravity

We have already talked about another class of chemicals that helps send signals in the body—neurotransmitters. How are neurotr
Darina [25.2K]

Answer:

Similarities: both are chemical messengers, both can have (but don't necessarily have) similar structures (made from amino acids), both can be produced by the central nervous system (hypothalamus produces some hormones), certain molecules can act as both hormones and neurotransmitters (example: norepinephrine).

Differences: neurotransmitters are released by neurons across a synaptic gap, have very short distances to travel, and act very quickly on the neighboring cell. Hormones are released by glands and often have to travel longer distances, which means that they are slower-acting. Also, hormones are typically used for regulation (negative feedback) while neurotransmitters are used for stimulation of a neighboring cell.
