The first generation of offspring from the cross of two parents is called the a. f1 generation b. f2 generation c. short generation d. p generation

Option A, F1 generation

Explanation:

The first cross between any two parents resulting into a set of offspring with similar or varied genotype is known as the first generation. First generation is represented by F1

However, when the offspring produced in the first generation are crossed among themselves to produce offspring with similar or varied genotype , then this cross is known as the second generation. Second generation is represented by F2

Hence, option A  is correct

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
