If the "A" represents red flowers and "a" represents green glowers, what are the chances of the flowers being green?

50%.

Explanation:

The A allele, which corresponds to red flowers is dominant, meaning if one is present, the flower is red. This generates Aa, which matches 2 squares, denoting a 50% in 4 total boxes. The a allele, corresponds to green flowers but is recessive, meaning both alleles must correspond to said trait to be expressed. 2 squares fit this scenario, making another 50% chance. Therefore, the answer would be 50%.

50% chance
if you look at the table there is
Parent one: one dominant gene parried with a recessive gene
Parent two: two recessive genes
Any time this combination happens it will always be 50%

The source of the carbon dioxide that is used in photosynthesis is c. the atmosphere. In photosynthesis, plants use carbon dioxide and water to produce glucose and release oxygen and ATP. They take carbon dioxide from the atmosphere which contains the small amount of carbon dioxide (0.04%), but enough for photosynthesis.
