Explanation:
Breathing, is necessary as it repleneshes oxygen in cells; it also expels CO2 and water vapor, which are waste products from cellular respiration.
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 oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate (through the process of glycolysis in the cytoplasm).
overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP
Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.
This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water. For a breakdown of each:
- 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:
Anaphase.
Explanation:
We can see that the separated sister chromatids are being pulled by the cell's centrosomes (microtubules) from both poles of the cell.
Warmer, colder
Convection is the transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperature.
Warmer fluid is less dense so it rises and colder fluid is more dense so it sinks.
Bias is having emotional input or a preconceived notion of something.
example: you are judging a contest and your best friend is in that contest. you would want your friend to win, therefore you have bias
Answer: A variety of substances will dissolve oil, including gasoline and carbon tetrachloride -- both of which have non-polar molecules. Acetone is a special class of solvent called “dipolar aprotic” that, depending on the circumstances, can act as a weak acid or base; it dissolves oil and mixes with water as well.
