BRAINLIEST What stage of cellular respiration uses the high-energy electrons from NADH and FADH2 to form ATP molecules?
Krebs cycle
Electron transport chain
Fermentation
Glycolysis
Answer:
Krebs cycle
Explanation:
Electron transport chain
AD+ and NADH: NAD+ is an electron carrier that accepts a pair of high-energy electrons to become NADH. The NADH carries the high-energy electrons to the electron transport chain where they are used to build high-powered ATP molecules.

Compare and contrast bodily reactions driven by two parts of the ANS: the sympathetic nervous system and the parasympathetic nervous system. Provide examples where each system would be highly active.
Difference
The sympathetic nervous system prepares the body for the “fight or flight” response during any potential danger. On the other hand, the parasympathetic nervous system inhibits the body from overworking and restores the body to a calm and composed state.
Examples of parasympathetic responses
An easy acronym to remember how and where the PSNS works is SLUDD. This stands for:
Salivation: As part of its rest-and-digest function, the PSNS stimulates production of saliva, which contains enzymes to help your food digest.
Lacrimation: Lacrimation is a fancy word for making tears. Tears keep your eyes lubricated, preserving their delicate tissues.
Urination: The PSNS contracts the bladder, which squeezes it so urine can come out.
Digestion: The PSNS stimulates the release of saliva to promote digestion. It also enacts peristalsis, or the movement of the stomach and intestines, to digest food as well as release bile for the body to digest fats.
Defecation: The PSNS constricts the sphincters in the intestine and moves digested food material down the digestive tract so a person can have a bowel movement.
Examples of the Sympathetic Nervous System Response
The classic case of SNS response is a physical danger, especially with a potential predator, and the preparation of the body for either fight-or-flight. The overall system is designed to enhance voluntary muscle activity while shutting down all non-essential functions.
Arterioles and veins in most vascular beds constrict, reducing blood flow to the skin and digestive organs. Sphincters in the digestive organs also constrict, to control the flow of food from one organ to the next. However, coronary blood vessels, pulmonary circulation and parts of the respiratory tree respond with dilation, to enhance cardiac output. The heart beats with greater contractile force and at a higher frequency as well. Vasoconstriction in many parts of the body also increases blood pressure.
Similarity
Both are the part of ANS. Both originate from the spinal cord. Both have huge influence on physiological process of the body such as respiration, circulation, digestion, urination and reproduction.
The SYMPATHETIC nervous system drives fight-or-flight responses, whereas the PARASYMPATHETIC nervous system drives “rest and digest” responses.
The autonomic nervous system (ANS) comprises the sympathetic system and parasympathetic system.
The sympathetic nervous stimulates 'fight or flight' responses, whereas the parasympathetic system activates 'rest and digest' responses.
The sympathetic nervous system is involved in body reactions such as the acceleration of the heart, constriction of the blood vessels, etc.
The sympathetic nervous system is involved in body reactions such as lowering the heart rate, lowering the flow of blood to skeletal muscles, etc.
Some examples that activate the parasympathetic system include:

StressOverstimulationIn conclusion, the SYMPATHETIC nervous system drives fight-or-flight responses, whereas the PARASYMPATHETIC nervous system drives “rest and digest” responses.

compared to the surface temperature and luminosity of massive stars in the main sequence, the smaller stars in the main sequence are
Answer:
Betelgeuse
b.Polaris
c. Aldebran
d.Sirius
e. The Sun
Explanation:
arent sure
In comparison with the surface temperature and luminosity of massive stars in the main sequence, the smaller stars in the main sequence are: cooler and less luminous.
A star is a giant astronomical or celestial object that contains a luminous sphere of plasma and bounded together by its own gravitational force.
Generally, a star typically comprises two (2) main hot gases and these are:
I. Hydrogen (H).
II. Helium (He).
Main sequence refer to stars that can fuse hydrogen atoms in its core, to form helium atoms.
Some examples of a main sequence include the following;
Sun (closest to planet Earth). Antares. Canopus. Vega. Betelgeus.The luminosity of a star can be defined as the total amount of light radiated by the star per second. Also, it is measured in Watts (W).
In conclusion, smaller stars in the main sequence are cooler and less luminous than massive stars in the main sequence.

How does the use of wild-life/animals impact on the earth?
Answer:
Hope it helps...
Explanation:
Animals help us to save our environment. Some micro organisms such as bacteria help us clean the environment; others help plants by converting free nitrogen from air and feeding the roots. Some insects and earthworms help in agriculture by increasing fertility of the soil and also by increasing organic quality of soil.
Answer:
When a predator goes extinct, all of its prey is released from that predation pressure, and they may have big impacts on ecosystems. If there are too many deer, for example, they can really change the ecosystem because they can destroy forests, and they also carry diseases.
Plants that thrive in this type of climate are most likely adapted to which of these conditions
Answer:
Plants Adapting
Explanation:
Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.
