The most important element in living organisms is carbon and is found in all the four biomolecules; lipids, carbohydrates, proteins, and nucleic acids.

Carbon is the most important element in living organisms.

Carbon is an element that is considered as the foundation of life. From this element comes 4 types of biomolecules. They are lipids, carbohydrates, proteins, and nucleic acids.

These biomolecules have building blocks that we call as monomers . Like a Lego, it acts like Lego the blocks to form each molecule. Carbohydrates monomer is called monosaccharides.  The Lipids monomer is composed of two. They are fatty acids and glycerol. Proteins also have monomer. It is called amino acids.

Our DNA is composed of chains of nucleic acids which also have nucleotides as its monomer. All biomolecules contain these 3 atoms or elements. They are carbon, hydrogen, and oxygen.

In conclusion, the four biomolecules lipids, carbohydrates, proteins, and nucleic acids are all composed of carbon, hydrogen and oxygen.

Angina pectoris diagnosis impacts cardiac oxygenation.

Angina pectoris- Angina is a cardiac disorder brought on by a lack of blood flow to the heart muscle. This is often brought on by the hardening and narrowing of the arteries supplying the cardiac muscle. The syndrome is typical among elderly persons.

Oxygenation- Adding oxygen to a system, such as the human body. The term "oxygenation" also can refer to the procedure of administering oxygen to a patient or of mixing oxygen with a drug or other chemical.

Cardiac muscle- The myocardium, or cardiac muscle tissue, is a particular kind of muscular tissue that makes up the heart. This muscular tissue, which unconsciously contracts and relaxes, keeps the heart circulating blood throughout the body.

Bioaccumulation is the accumulation of the harmful chemical inside the body of an organism, at a rate which is faster than its excretion. Since it dies not gets digested properly and excreted, these chemical buildup and are transferred to the next organism in the food chain. As a result, the organism at the top-most level of the food chain has the maximum concentration of chemicals.

Bronchioles- Smaller and smaller passages, known as bronchioles, branch out from the major airways (bronchi), leading to air sacs (alveoli).

Alveoli- Small air sacs near the bronchioles' ends (tiny branches of air tubes in the lungs). While breathing in and out, oxygen and carbon dioxide are exchanged between the blood and alveoli in the lungs.

Active transport necessitates the movement of molecules, whereas passive transport does not necessitate the movement of molecules. Channel proteins are classified into two types: open channel proteins and gated channel proteins.

Carrier proteins, which change shape as they transfer their specific chemical across the membrane, are used in both passive and active transport. The sodium potassium pump and glucose exporters are two examples of carrier proteins found in our cells.

Channel proteins are proteins that can generate hydrophilic pores in cell membranes and transport chemicals along concentration gradients. Carrier proteins are integral proteins that can transfer molecules across the membrane in both directions, down and up the concentration gradient.

A negative feedback loop is a process in which the body senses a change and activates mechanisms to reverse that change. This is false.

When it comes to feedback loops, there seems to be a lot of confusion out there. So let's set the record straight: a negative feedback loop is NOT a process in which the body senses a change and activates mechanisms to reverse that change.

What is a negative feedback loop then? Well, it's simply a process whereby the body responds to a change by creating an opposing force that counters the original change.

For example, let's say your body temperature starts to rise. This increase in temperature is detected by the brain, which then signals the body to sweat. The sweat then helps to cool the body down, reversing the original change (increase in temperature).

So, in short, a negative feedback loop is a process that helps the body maintain homeostasis (a state of balance).

This statement is true as any living system is capable of evolving, as time changes with it the environmental features are also capable of changing. Evolution is a gradual process that takes place over time and the environment keeps on changing. No, this is not Darwinian evolution, as Darwinian evolution strictly depends on adaptation through generations that are favored by the nature. The ecosystem can evolve as they do not require inheritance or reproduction or fitness for its evolution.

Explanation:

Metabolism is slow and heat is generated. Endotherms use metabolic heat to maintain a stable body temperature, but not exogenous heat.

An animal's "baseline" metabolic rate  is measured as the basal metabolic rate (BMR) for endotherms or as the standard metabolic rate (SMR) for exotherms. Among endotherms, smaller animals tend to have higher  basal metabolic rates per gram than larger animals (“hotter” metabolism). The same applies to external temperature, although groups cannot be compared. Your metabolic rate depends on your activity level. A more active animal has a higher metabolic rate than a less active animal. Some animals go into a state of lethargy where their metabolism slows down. Winter hibernation and  summer hibernation are forms of lethargy.

Ectotherms, however, lower their metabolic rate as the outside temperature drops in order to preserve body temperature.

The Krebs cycle will form as a product: 6 NADH, 2 ATP, 4 CO2, and 2 FADH₂

The Krebs cycle is a process in which the complete oxidation of metabolic fuels to CO2 occurs through a series of cyclic oxidative reactions. All the enzymes of the cycle will be located in the mitochondria and this will coincide with the location of the pyruvate dehydrogenase complex and beta oxidation enzymes, which are the main sources of acetyl-CoA. One of the functions of the cycle is the generation of reducing equivalents that are used to generate ATP in the sequence of electron transport and oxidative phosphorylation.

Oxidation of acetyl-CoA occurs in four reactions that transfer electrons to the coenzymes NAD or FAD. In other reactions of the cycle the bonds are rearranged to facilitate this transfer.
