Answer:
because there is not a lot of anything in that layer so anything that comes into it creates a reaction, heat
Explanation:
Because there are relatively few molecules and atoms in the thermosphere, even absorbing small amounts of solar energy can significantly increase the air temperature, making the thermosphere the hottest layer in the atmosphere"
Answer: True
Explanations:
Light diffraction is the bending of light around objects with very small openings whose sizes approach the wavelength of light.
Light scattering occurs in the transmission medium (such as air) due to density fluctuation, droplets, or particles in the transmission medium.

The vacuoles in a plant cell are much more larger and take up a large portion of the cell but animal cells vacuoles tend to be smaller. The plant cells vacuole is permanent when the animals is temporary. A plant cells vacuole is formed by budding off the membrane, the animal cells vacuole is formed by the organelle called the Golgi body.
Answer:
The correct option is<em> A. Active transport moves substances against the concentration gradient.</em>
Explanation:
Active transport can be described as a transport mechanism in which molecules tend to move against the concentration gradient i.e from an area of lower concentration to an area of higher concentration. Energy is needed for this process to occur.
Facilitated diffusion can be described as a phenomenon is which molecules move along the concentration gradient i.e from a higher concentration to a lower concentration with the help of trans- membrane integral proteins
