What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
How does volcanic activity affect climate?
The main effect on weather right near a volcano is that there is often a lot of rain, lightning, and thunder during an eruption. This is because all the ash particles that are thrown up into the atmosphere are good at attracting/collecting water droplets. We don't quite know exactly how the lightning is caused but it probably involves the particles moving through the air and separating positively and negatively charged particles.
What structure controls the passage of substances into and out of the cell?
cell membrane
During action potential transmission many ions cross the neuronal membrane at right angles to the membrane what travels along the membrane and acts as the signal?
neurotransmitters
What does the water cycle transport?
Water waves are a mix of longitudinal and transverse waves. Particles of water actually travel in circles. If the particles move in clockwise circles, for example, then the wave propagates to the right. To understand water waves, it's important to understand that water is not compressable. Sound waves are longitudinal waves where particles move back and forth and create areas of temporarily increased and decreased density and pressure. That is not possible with water waves, since the density can't significantly increase. Water also can't move as a transverse wave alone. If the height of the water increased without moving back and forth, the water would have to stretch vertically. Instead, when water particles move toward each other to the crest of a wave, they also pile up and increase the height of the water. Consider a wave propagating to the right. The particles move at their maximum rightward speed at the crest of the wave, so they catch up slightly with other particles still on the face of the wave. The height of water increases to the right. Then the crest passes the particle, and it begins to slow down because it tends to slide down the back of the wave. About halfway down the back of the wave, it has completed the first quarter of its circular path. It slows to a stop and starts moving left. At the trough of the wave, it is moving at its maximum leftward speed and has completed the right half of a circle. It is moving away from particles to its right, so the water height to its right decreases. Then the particle is caught by the face of the next wave. The face of the wave accelerates it to the right and slows its leftward motion until it stops about halfway up the face of the wave. Then it accelerates to the right until it reaches its maximum speed again at the crest of the next wave. Particles under the surface of the water move too, motivated by variations in pressure. They move in similar circles to the surface particles, but smaller circles deeper in the water.

If a transverse wave is moving from right to left the individual particles in the medium are moving?
No. the individual particles are not moving in the right to left direction. rather, they moves up and down. it is the wave that is going right to left.
Are the particles in a gas moving fast with no forces of attraction between them?
Yes that's right
What effect Deflects moving particles such as air to the right above the equator?
Coriolis effect
What is process that moves molecules across a cell membrane from regions of lower concentration to higher concentration?
The process that can move molecules from a low to a high concentration through a cell membrane is active transport.
These move through earth by causing particles to move at right angles to the waves direction?
S Waves

Where did most of the alpha particles fired at the foil go in the gold foil experiment?
Most of them went right through.

When moving the slide left on a microscope which direction does it appear it is moving in?
A microscope inverts and transposes an image. A move left will therefore appear to move right through the eyepiece.
