The cardiovascular system works with the respiratory system to circulate blood and oxygen throughout the body. The cardiovascular system includes the heart, blood vessels, and blood.

The cardiovascular system works in conjunction with the respiratory system to ensure that oxygen is delivered to the body's cells and that carbon dioxide is removed. When we breathe in, oxygen enters the lungs and is transferred to the blood, where it binds to hemoglobin. The oxygen-rich blood is then pumped by the heart to the body's cells, where it is used to produce energy. At the same time, respiratory system carbon dioxide, a waste product of cellular metabolism, is removed from the cells and carried cardiovascular system by the blood to the lungs, where it is exhaled. This process, known as respiratory system, is a continuous respiratory system cycle that ensures the body's cells receive the oxygen they need to function properly and that waste products are removed.

In general, a Point mutation refers to alteration in a single base pair of DNA by substitution, deletion, or insertion of a single nitrogenous base. Most common example of point mutation is sickle cell anemia. that consists of mutation in a single base pair in the beta-globin chain of hemoglobin pigment in the blood cells. Thus, An insertion can involve the addition of any number of nucleotides, that can be a single nucleotide or an entire piece of a chromosome.

The most genetic information is inherited in humans on the x-chromosome.

In bacteria, each messenger RNA (mRNA) serves as a template for the production of one or more particular proteins. Messenger RNAs (mRNAs) carry information from DNA. Translation is the process by which the primary amino acid sequence of a protein is established from the nucleotide sequence of an mRNA molecule.

Their mother passes one copy on to them through the egg, while their father passes the other one along sperm. Each egg and sperm have a single set of 23 chromosomes. Two copies of each chromosome and two copies of each gene are present when the sperm fertilizes the egg, resulting in the formation of an embryo.

The correct answer to the question is b. Fatty acids of less than 12 carbons enter the lymphatic system packaged in chylomicrons.

After absorption, fatty acids are taken up by the lymphatic system and transported in the form of chylomicrons. Chylomicrons are lipoproteins composed of lipids, proteins and other substances, and are the largest form of lipoproteins.

Chylomicrons are mainly composed of triglycerides and cholesterol esters, and are responsible for the transport of fatty acids from the small intestine to the rest of the body. These chylomicrons contain fatty acids of less than 12 carbons, which are then transported throughout the body via the lymphatic system.

Once the fatty acids reach the liver, they are either metabolized or stored as fats. In order to enter the blood, fatty acids of 16 or more carbons must be packaged in lipoproteins, such as very low density lipoproteins (VLDL). These VLDLs are then transported to the liver via the portal vein.

In summary, fatty acids of less than 12 carbons enter the lymphatic system packaged in chylomicrons, while fatty acids of 16 or more carbons enter the blood and then the liver via the portal vein.

A single amino acid substitution in a protein can cause a dramatic difference in the final shape of red blood cells through changes in the protein's conformation.

Proteins are composed of a sequence of amino acids and their three-dimensional structure is determined by the interactions between different regions of the protein, such as the hydrogen bonds, electrostatic interactions, and hydrophobic interactions. These interactions help to keep the protein in its specific conformation, which is essential for its function. A single amino acid substitution can alter these interactions and disrupt the protein's conformation. This can lead to changes in the shape and properties of the protein.

In the case of red blood cells, a single amino acid substitution in a protein that is responsible for maintaining the shape of the cell can cause the cell to change shape. For example, a substitution in the protein spectrin, which is a component of the cell membrane, could cause the membrane to be more or less flexible and thus resulting in a change in shape of the red blood cell. This change in shape can affect the mechanical properties of the cell and can have a significant impact on its ability to flow through capillaries and deliver oxygen to tissues.

The four major principles of natural selection are that populations of living things change over time due to a straightforward mechanism called natural selection.

In fact, it is so straightforward that it can be divided into five simple processes, referred to here as VISTA (variation, inheritance, selection, time, and adaptation). Most attributes are inherited, more offspring are generated than can survive, and offspring with more attractive traits will survive and have more offspring than those with less favorable traits.

These three principles result in natural selection, which is an unavoidable process. More environment-adapted organisms are more likely to survive and pass on the genes that contributed to their success. Over time, species change and diverge as a result of this process.

The number of ATP yielded through fat metabolism which makes 9 molecules of acetyl CoA is 108 ATP.

The process of metabolic reactions which convert fatty acids to acetyl CoA is called beta-oxidation. Through multiple steps in beta-oxidation, fatty acids are broken down to produce energy (ATP). Before producing the energy, fatty acids which are made up of carbons must be converted into acetyl CoA in advance.

If 9 molecules of acetyl CoA are produced, it indicates that the fatty acid has 18-Carbons. In other words, each acetyl CoA contains two carbon atoms.

Each acetyl CoA that has been produced, will enter into the citric acid cycle or known as Kreb’s cycle. This cycle yields 3 NADH (9 ATP), [tex]FADH_{2}[/tex] (2 ATP), and 1 ATP. The total ATP result is 12 ATP.

when there are 9 molecules of acetyl CoA, the ATP yielded is 9 x 12 ATP = 108 ATP.

Thus, if each fatty acid in a certain fat can make 9 molecules of acetyl CoA, the amount of ATP that can be made is 108 ATP.
