Answer:
The correct answer is C
Explanation:
A plant consumes all the oxygen photosynthesis generates. It also uses all the carbon dioxide respiration creates. As a result, no gas exchange takes place with the environment. Bright sunlight – Photosynthesis uses carbon dioxide and makes oxygen faster than respiration produces carbon dioxide and consumes oxygen

The mass percent of oxygen in Barium perchlorate is is 38%.
The molecular mass of Barium perchlorate (Ba(ClO4)2) is 336.2282 g/mol.
Percent composition of Oxygen will be = [(Molecular mass of Oxygen X 8)/ Molecular mass of Barium perchlorate] X 100%
= [(15.99 X 8)/336.2282] X 100% = 38%
I’m looking for this too, ain’t no way your in collage learning this.
Answer:
Differential reproduction leads to a change in allele frequencies over time. This occurs because of natural selection favoring "successful" individuals that produce more viable offspring.
The sickle-cell allele is maintained in populations exposed to malaria through balancing selection, since heterozygous individuals have protection against the disease.
The body can only synthesize 11 of the 20 amino acids, all other nine needs to be incorporate with food and those are the ones that we call essential amino acids.
Most of the metabolic cycles use carbon coming from glycolysis, the pentose phosphate pathway or the Krebs cycle.
