Explanation:
Acetyl-CoA, the substrate for cholesterol synthesis is produced by the catabolism of carbohydrates, fatty acids and certain amino acids. Cholesterol comes from both diet and de novo synthesis from acetyl-CoA, biosynthesis that takes place preferentially in the liver; and to a lesser extent, in the intestine.Acetyl-CoA is converted to mevalonate, mevalonate is converted to squalene through successive reactions of transfer of prenyl groups. Squalene becomes lanosterol. Lanosterol is converted to cholesterol after 21 other successive, enzymatically catalyzed reactions.

All but one response is a human response to a change in environmental temperatures. That is sweating. The correct option is D.
What is sweating?Sweating is a physiological process that aids in controlling body temperature. Sweating is the expulsion of a salt-based fluid from your sweat glands, which is also known as perspiration.
Four different strategies exist for humans to react to environmental stress: adaptation, developmental adjustment, acclimatization, and cultural reactions.
A genetically based property known as an adaptation has evolved because it aids living things in surviving and procreating in a certain environment.
Sweating can be brought on by changes in your body temperature, the environment, or your emotional state.
Therefore, the correct option is D) sweating.

A) left ventricle
B) right atrium
C) right ventricle
D) pulmonary trunk.
please help and define the difference in pulmonary circuit and pulmonary circulation. thanks
Pulmonary trunk does not belong to pulmonary circuit.
What is pulmonary circuit?The circulation provides oxygen and blood to all the parts of the body. The circulation is of two types pulmonary circulation and systemic circulation. When blood moves from heart to other organs it is called systemic circulation.
When blood moves from heart to lungs is called pulmonary circulation. The circulation involves four chambers such as left atrium, left ventricle, right atrium and right ventricle.
Pulmonary trunk is not a part of pulmonary circuit. Blood will flow from auricles to ventricles.
Therefore, Pulmonary trunk does not belong to pulmonary circuit.

What type of photoreceptor cell allows us to see gray tones in dim light, and provides our peripheral vision
Answer:
Rods.
Explanation:
There are two types of photoreceptor cells, the cones, and the rods.
The cones adapt our vision to bright light and allow us to see colors. On the other hand, rods photoreceptors make us see in the dark and do not perceive many colors; that is why we can not distinguish colors in the dark. Also, they provide peripheral vision since they are on the external edges of the retina.

What organelles are associated with carbohydrates?
Answer:
The only organelle that is associated with carbohydrate synthesis is the Golgi Apparatus.
Explanation:
Hope this helps!
The organelles which are associated with carbohydrates are mitochondria and the endoplasmic reticulum (SER).
What are Mitochondria?Mitochondria may be defined as the double-membrane bound cell organelle which is found in the cytoplasm of the cell. It was first recognized by Kolliker in muscle cells of insects in 1880.
Mitochondria are known as the "Powerhouse of the cell". This is because the energy required for various activities is released by mitochondria in the form of ATP. This organelle also oxidizes the pyruvic acid and forms energy in the form of ATP.
The smooth endoplasmic reticulum is directly associated with carbohydrate metabolism along with other metabolic processes like the synthesis of lipids, detoxification, etc.
Therefore, mitochondria and the endoplasmic reticulum (SER) are the organelles that are associated with carbohydrates.
