True
Explanation:
Natural selection actively seeks to help an organism because it prevents an organism from completely going into extinction. Natural selection is central to the process of evolution of an organism.
- Natural selection is the process by which organisms that are more suited to the environment are favored compared to those that cannot adapt.
- The process allows for an organism to evolve and adapt to new changes in the environment more readily.
- This theory was proposed by Charles Darwin.

Explanation:
While the question is incomplete, typical parts of respiration can be classed as...
Not an output or input: ADP, glucose, O₂, ATP
Input: pyruvate, NAD⁺, coenzyme A
Output: acetyl CoA, CO₂ NADH,
O2 and glucose are the main inputs used in respiration...
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP
Further Explanation:
In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced.
Respiration in the mitochondria utilizes acetyl coA, which is produced from the activity of coenzyme A on pyruvate, along with oxygen for the production of ATP in the Krebs’s cycle via the oxidization of pyruvate( through the process of glycoysis). The electron transport chain, in which oxygen functions as the terminal electron acceptor occurs in both plants and animals.
- Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules.
- The Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
- The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

Answer:
muscle cells in the legs of a marathon runner
Explanation:
Mitochondria are the powerhouse of cells and serve as a site for the aerobic stage of cellular respiration. Cellular respiration is complete oxidation of nutrients in the presence of oxygen to produce a large number of ATP molecules. Therefore, the cells that require more ATP molecules as an energy source would most likely have a greater number of mitochondria.
Muscle cells are responsible for body movement. Muscle cells in the legs of a runner would require a constant supply of ATP during running since muscle contraction requires ATP. To sustain the continuous muscle contraction during the marathon, the muscle cells in the legs of the runner would have most number of mitochondria.
