The statement that would best keep the world's oxygen supply from decreasing:
a.Planting trees in forests that have been harmed
Trees decrease the urban heat island effect via evaporation cooling and lessening the amount of sunlight that reaches parking lots and buildings.
Light energy (from the sun) is used to convert carbon dioxide and water into glucose and oxygen in the process of photosynthesis.
carbon dioxide + water --> glucose + oxygen
the light energy from the sun is then trapped in the glucose. in order to retrieve the chemical energy stores within the molecule, the bonds have to be broken.
The answer to your statement is TRUE!!
Answer:
2 n = 61 Chromosomes
Explanation:
If the plants that are produced are fertile then they must have a chromosome number hybrid of previous two species and that is 122. This is an example of tetraploidy. It is crucial that the chromosome number of the species should be even otherwise the pairing will result in a mismatch and the produced offspring will be a sterile hybrid.
