The sun's energy drives various processes on earth. One of these processes is photosynthesis in plants whereby light energy is converted into chemical energy by forming carbohydrates from carbon dioxide plus water, which is a process which usually gives off oxygen which animals need to breathe. Another process driven by the sun's energy could be evaporation of water into the air to form water vapour and clouds which then precipitate when cooled off over mountains so is involved in the water cycle.
Answer is: the part of an experiment that stays the same though out the experiment is constant.
<span>Constant is a quantity that does not change.
</span>Experimental variable<span>, which is the also part of an experiment, is affected by the experiment (have change).</span>
Answer:
I believe its option b. carbon dioxide.
Answer:
nitrogen can be changed into macromolecules like proteins and nucleic acids (DNA and RNA)
Explanation:
Answer:
The minerals will not be move or transported to other part of the plants because active transport require energy.
Explanation:
Active transport is a process where molecules and ions are move against a concentration gradient by using energy.
This process require energy, for ions or molecules of minerals to be taken up by plants, it is first moved to the root hairs where they are in high concentration against in dilute concentration on soil Active Transport then occur in the roots where it is taken up to the plants with the use of energy.
If there is not enough energy, active transport will not occur and the minerals will remain in the root hair and will not be move to other part of the plant.
