<em>Respiration removes oxygen from the atmosphere, and photosynthesis puts oxygen into the atmosphere</em><em>.</em>
<u>Explanation</u>:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
A single base-pair deletion would cause a frameshift mutation, disrupting every codon sequence read after it. A single base-pair change, however, only affects one codon. It is therefore less likely to cause harm.
