Answer:
The answer is a Carbohydrate!
The greenhouse gases effect the environment by leading to climate change and global warming.
Due to green house gases the earth become warmer than normal.This affect weather patterns which led to global warming and climate change.In the last 3 million years the amount of greenhouse gases in our atmosphere is the highest which led to global warming.
By using a genetic diagram or a punnett square, we can show the the result of a cross between RR and rr.
The result of the genotypes should all be Rr.
This means all their offsprings should have the dominant trait being expressed.
Therefore, the percentage to this should be 100%.
The picture above is an example of using a punnett square finding the possible genotypes of the offsprings.
The answer is endothermic.
Endothermic reactions are reactions that need energy to form a product.
Exothermic reactions are reactions that release energy.
Photosynthesis is a process in which energy of sunlight is used to convert carbon dioxide and water into glucose and oxygen. Hence, the energy of sunlight is needed for photosynthesis. So, photosynthesis is endothermic.
