Answer:
i would say A. Both are needed as a reactant of cellular respiration.
Explanation:
While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. ... Without oxygen, much less ATP would be produced.Aug 31, 2018
Answer:
Combined parenting leads to faster reproduction
Explanation:
Genetic diversity or variations in the physical appearance of organisms is caused by genetic or environmental factors. Reproduction brings about variation through gamete formation, fertilization and mutations.
During prophase 1 of meiosis, homologous chromosomes pair to form bivalents. The crossing over at the chiasmata results in new gene combination and variations.
Fertilization permits parental genes to be brought together. This causes variations in members of the same family.
Mutation is the spontaneous change in genetic make-up. These changes may be inherited by offspring bringing variations. However, combining parenting does not increase genetic diversity.
