Answer: D. some components of the cycle are used as building blocks for certain anabolic pathways.

Explanation:

The citric acid cycle or Kreb's cycle is the part of the cellular respiration. It is a sequence of chemical reaction which is used by all the aerobic organisms so as to store energy by the process of acetyl CoA oxidation derived by the process of fats, proteins and carbohydrates into forms like carbon dioxide and adenosine triphosphate (ATP).

The acetyl CoA is used in the process of synthesis of fatty acids. The citrate is used for the synthesis of cholestrol. The oxaloacetate and alpha ketogluterate are used for the synthesis of aminoacids. Succinyl CoA is used for the synthesis of poryphrins and fatty acids.

STatiana [176]

Answer:

The correct answer is - The cranial nerves and the spinal nerves.

Explanation:

The central nervous system or CNS includes the brain and the spinal cord of the nervous system where it takes sensory information, integrates, and responds accordingly. The spinal cord acts as a conduit for signals between the brain and the rest of the body.

Spinal nerves and crania; both play an essential role in taking sensory information and respond accordingly. Spinal nerves are nerves that help in sending motor, sensory, and autonomic signals between the CNS and the body. The cranial nerves supply information to the CNS and then from the CNS to the body.

Thus, the correct answer is - The cranial nerves and the spinal nerves.

PLS ANSWER FASTTT What is the difference between Love waves and Rayleigh waves?
MAXImum [283]
<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

\huge\boxed{\text{Option D}}

<h2>_____________________________________</h2>

\huge\textbf{Releigh Waves}

A Rayleigh wave is a seismic surface wave causing the ground to shake in an elliptical motion(they move in a surafce rolling manner). A seismic wave means a earthquake wave, so Rayleigh wave is realted to the motion of earth and its crust. Rayleigh waves are formed when the particle vibrate with the combination of both transverse and longitudinal waves. This vibration gives rise to a wave which moves elliptically backwards that is Rayleigh Wave.  Rayleigh waves are really fast they move with the spped 10 times faster than the speed of light.  Rayleigh waves are generated by the interaction of P or compressional and S or shear waves(P ans S Waves are inside the Earths Crust) at the surface of the earth.

<h2>_____________________________________</h2>

\huge\textbf{Love Waves}

Love waves or Q waves or Quer Waves are surface seismic waves that cause horizontal shifting of the Earth during an earthquake. A Love wave is a surface wave having a horizontal motion only. Love waves are formed when the earth particles move in a transverse wave manner creating a wave travelling perpendicular to the direction the wave.

What is the high energy molecule formed at the end of cellular respiration called?
expeople1 [14]

Answer:

Explanation:

ADP (Adenosine diphosphate) is a starting material in respiration. Through the process of respiration a 3rd phosphate is added to the compound to make it ATP (Adenosine Triphosphate). This extra phosphate in the end product is what allows the cell to use the compound for energy.

NAD and NADH are used in the electron transport chain but not going to be the energy molecule
