Answer:
The correct answer is option d. "Humans share a deep evolutionary ancestry with other animals that can be seen in reappearing atavisms or body parts that no longer seem to have a function".
Explanation:
A vestigial organ or vestigial structure is an anatomical feature that no longer seems to have a function, but they used to serve a purpose in an ancient form of an organism in the past. Atavisms, are vestigial organs that seem to reappear after having been lost through evolutionary change. Charles Darwin's studies on the subject made him conclude that humans share a deep evolutionary ancestry with other animals that can be seen in reappearing atavisms or body parts that no longer seem to have a function. He published his studies on human vestigial organs and atavisms in his book "The Descent of Man, and Selection in Relation to Sex".

When a high Hydrogen+ ion gradient is built on the inner membrane of the mitochondria and a low concentration on the opposite side, it allows hydrogen ions to diffuse through the protein ATP Synthase, which uses electrons and Phosphate to turn ADP into ATP.
Bacteria is not included as an abiotic factor in an ecosystem.
The right answer is non rebreather.
A non-rebreather mask (NRB) is mainly used to provide oxygen to treat hypoxia, in which arterial blood oxygen saturation is less than 90 percent.
Non-rebreather masks offer an increased level of moisture towards the nasal passage, which can become inflamed and irritated with prolonged oxygen treatment. Increased humidity also increases the patient's respiratory secretions.
