1.The thermosphere: is used for orbitting satellites and increases in temperature as altitude increases.
2.Convection currents in the mantle cause the movement of crustal plates.
Open systems are the most common in nature
Answer: The structure is chloroplast.
Explanation: Photoautotrophs are organisms that can synthesize food using light energy and carbon dioxide via photosynthesis.
Photoautotroph is a combination of two words: photo which means light and autotroph which means an organism that can manufacture its own food.
A photoautotroph manufactures its own food in a process known as photosynthesis. Photosynthesis is a process by which plants manufacture organic foods such as glucose using light energy, carbon dioxide and water. This process takes place in the chloroplast. A chloroplast is an organelle found in plant cells that contains chlorophyll which is the pigment that absorbs the light used in photosynthesis.
Answer:
Relative velocity simply means velocity relative to a certain observe point, in this case, the river shore.
This is a type of complex movement; a boat is moving with a certain velocity, let's say 8 m/s. However, the river this boat moves on also has its velocity, let's say 2 m/s. Since the shore isn't moving, the velocity of the boat relative to the shore will be simple resultant velocity of the boat's and the river's velocities.
Let's illustrate this with two examples:
1) if the boat is moving downstream both are moving in the same direction, so the resultant will be 8 m/s + 2 m/s = 10 m/s.
So, any spectator looking at the boat from the shore will think its velocity is 10 m/s, when in reality it's 8 m/s.
2) if the boat is moving upstream, these two velocities have opposite directions, so the resultant will be 8 - 2 = 6 m/s
So, as a short summary, relative speed is an object's speed in regard to another chosen referent point.
