Answer: Option C
Explanation:
The amitochondriate eukaryotes may have genes that have been derived from purple alphaloproteobacteria because they do not have the mitochondria which is needed to optimize energy production in the presence of oxygen, can live and exist in a condition with little to no oxygen which is a characteristic of proteobacteria and hence are anaerobes obtaining energy by anaerobic respiration. They may have also undergone the endosymbiont theory but due to their environment which has little to no oxygen. They do not have a need for the mitochondria organelle and in the process lose this organelle.
Ans.
A nerve is defined as a bundle of axons. Axons are slender, long projections protruded from neurons in PNS (peripheral nervous system). The nerves provide a pathway for the transmission of electrochemical nerve impulses from axons to the other peripheral body organs.
Thus, the correct option to be fill in the blank is 'bundle of axons.'
The two processes are coupled throughout the mitochondrial inner membrane that together make up oxidative phosphorylation are: Electronic transport chain and ATP synthase.
NADH and FADH2 formed during glycolysis; fatty acid and amino acid breakdown and the citric acid cycle contain high-energy electrons.
Oxidative phosphorylation is the process by which these molecules are oxidized by transferring their electrons to O2 and the resulting energy is used in the form of ATP synthesis.
This metabolic process is formed by a set of complex enzymes, located in the inner membrane of the mitochondria, which catalyze various oxidation-reduction reactions.
Oxidative phosphorylation includes two coupled mechanisms:
- Electron transport chain that the set of enzymatic complexes embedded in the mitochondrial membrane that oxidize NADH and FADH2 generating a proton gradient.
- ATP synthase that harnesses the energy of the proton gradient to produce ATP.
Both the electron transport chain and ATP synthase are embedded in the membrane, and energy is transferred from the electron transport chain to ATP synthase by the movement of protons through the membrane, in a process called chemiosmosis.
Therefore, we can conclude that oxidative phosphorylation works with two types of reactions that are coupled, the electronic transport chain that releases energy, while the other ATP synthase uses that energy to carry out its reactions.

Answer:
Planet- A large round object is in space and and has an orbit around some kind of star.
Moon- Smaller than planets, moon are usually found orbiting a planet.
Comet- A large ball of ice that lets off a tail of cas escaping from the ice. Commets are found orbiting stars but have a much larger orbit. They are smaller that planets (usually).
Asteroid- A large chunk of rock that floats around in space. Ussualy found in large group orbiting a star or planet.
Dwarf Planet- Pretty much just a planet, but much smaller. They can also come in many differn't shapes, whilst planest usually only are spheres.
