<span>Biotic factors are the living components of an
ecosystem. They are sorted into three groups: producers or autotrophs,
consumers or heterotrophs, and decomposers or detritivores.</span>
The answer would be:
Passive transport
Active transport
Why?
There are two ways molecules can move across membranes within the cell. What makes the two different is the use of energy.
PASSIVE transport is the movement of molecules DOWN the concentration gradient. The molecules move from areas of higher concentration to lower concentration. This does nor require energy. Comparing it to the scenario, the child starts from a higher area and ends at a lower area. Going down a slide does not take energy. The child simply goes down it.
When you talk about the child going UP a slide, think ACTIVE transport. Unlike passive transport, active transport requires energy, because the molecules move AGAINST the concentration gradient. The movement of molecules in this type of transport is the opposite, it goes from lower areas of concentration to higher areas of concentration.
Hopefully, this has been educational for you and was able to help you understand the difference between the two.
Newton's law of gravity helped to change the initial view that the Universe was supported by some mystical force or object.
<h3>What did Newton say held the Solar system together?</h3>
Newton's explanation that the Solar system was held together by the force of gravity helped to explain so many observation which were not explained before.
Newton's explanation that objects were attracted to one another by the force of gravity helped to change the view that the Universe was held together by some mystical or magical force or that the earth and other planets were supported on something.
Therefore, Newton's law of gravity helped to change the initial view that the Universe was supported by some mystical force or object.
