The Y chromosome lacks any genes for clotting factors. Males only have one allele of factor IX and one allele of VIII, . In humans, the allele for haemophilia (XH) is dominant to the allele in normal blood clotting (Xh).
What factors lead to haemophilia?A mutation or change in the one of the genes, which codes for the proteins that make the clotting factor necessary for a blood clot, results in haemophilia. The clotting protein may no longer exist or function improperly as a result of this alteration or mutation. Here on X chromosome are these genes.
What is hemophilia's primary symptom?Bleeding is the primary haemophilia symptom. Mild cases might not be discovered until much later on in life, after severe bleeding from a wound or surgery. In the worst situations, bleeding happens unexpectedly. Anywhere inside the body can bleed, and bleeding in joints is common.

Predict what could occur to a gene if a base is substituted, inserted, or deleted. Consider the impacts of these changes on the reading frame and on the protein that is produced.
This is for PLTW Biomed
Answer:
A base substitution occurs when a single nucleotide is replaced with another nucleotide. This can cause a change in the encoded amino acid, leading to an alteration in the protein's structure and function. An insertion or deletion of a base can disrupt the reading frame of the gene, resulting in a shift in the codons and a change in the encoded amino acid sequence in the protein. This can lead to a change in the protein's structure and function, and in some cases, the protein can become non-functional.
Suppose a pigeon breeder finds that about one fourth of the eggs produced by one of
his prize pairs do not hatch. Of the young birds produced by this pair, two thirds are
males. Give a possible explanation for these results. (Remember the mechanism of sex
determination in birds.
The female pigeon might carry a sex-linked lethal allele that affects only males and reduces their hatching rate. In birds, the male eggs offspring have ZZ chromosomes.
while females have ZW chromosomes. A lethal allele present on the Z chromosome could affect male hatching, leading to a lower ratio of males. The higher number of females produced could be due to the presence of the lethal allele in only the male eggs offspring. The presence of sex chromosomes, and the female is the heterogametic sex (ZW) and the male is homogametic (ZZ). If a female pigeon carries a lethal allele on its Z chromosome, it will only affect male eggs offspring, who inherit only one Z chromosome from their mother and one from their father. This can result in a reduced hatching rate of male eggs offspring.

During life, blood will travel through the circulatory system. The proper sequence as blood leaves the heart, travels to tissue, and returns back to the heart is: D: artery, B: arteriole, A: capillary, C: venule, back to the heart.
The circulatory system is responsible for transporting blood, oxygen, and nutrients throughout the body. When blood leaves the heart, it enters the arteries, which are larger blood vessels that carry blood away from the heart. The arteries then branch into smaller vessels called arterioles, which deliver blood to the capillaries, the smallest blood vessels in the body.
The capillaries are the site of exchange between the blood and the tissues. Oxygen and nutrients are delivered from the blood to the tissues, while waste products are taken up by the blood for removal from the body. The blood then leaves the capillaries and enters the venules, which are small blood vessels that converge to form veins. The veins then carry the blood back to the heart, completing the circulatory cycle.

Globulular polypeptides are those that are folded into a roughly spherical form and may contain a variety of secondary structures.
Dipole-dipole interactions and hydrogen bonds between polar amino acids, ionic connections between charged side chains, and hydrophobic interactions between nonpolar amino acids all contribute to the formation of this structure. Many proteins start folding even as the polypeptide chain is being translated.

A polypeptide may coil or fold back on some of its sections. secondary structure and the hydrogen bonds between the coils or folds keep them in place. The primary structure is nothing more than the arrangement of amino acids after translation. The secondary structure of proteins is a result of interactions between the carbonyl, amino, and side groups of the amino acid polymer backbone inside the chain.

Hemophilia A is an X-linked recessive disease. If a mother without the disease and a father without the disease have one son diagnosed with hemophilia, what is the probability that a future daughter they have together will also be afflicted with hemophilia?
%
Answer:
No chance whatsoever that she will have a severely afflicted daughter.
0%
Explanation:
Rare X-linked illness, hemophilia A, affects a small percentage of the population. Because it is recessive, it only manifests in females when both X chromosomes are present. However, in men, the presence of only one X chromosome is sufficient to cause the condition.
Since X-linked recessive traits are passed down from mothers to their daughters, if a woman has a son who is afflicted by the illness, then her daughter will also be a carrier. Because of this, there is no certainty that the daughter will develop hemophilia A, although she may be a carrier.
rennilase is going to be added in powder form to warmed milk during this lab. explain the affects the enzyme will have on the warmed milk in terms of the subsrate acted upon and product formed
Rennin, also known as chymosin, is a protease enzyme that coagulates the milk protein casein.
When rennin is added to warm milk, the protein casein present in the milk is hydrolyzed into smaller peptides and amino acids. Rennin acts specifically on the phosphopeptide bonds in casein, causing the protein to denature and aggregate into clumps, which results in the formation of curds. The curds have a solid and gel-like texture and are used in the production of cheese.
Rennin is a crucial component in the cheese-making process as it is responsible for the coagulation of the milk, which is a crucial step in determining the texture and flavor of the final cheese product. The reaction rate and efficiency of rennin depend on various factors such as temperature, pH, and the presence of other substances such as calcium ions.

The cohesion tension theory will explains the ascent of sap through the Xylem tissues. The water as well as other nutrients are absorbed by the root and are transported to the leaves by the xylem.
Ascent of sap is the translocation of the water molecules from the root to the leaves. It is an upward movement.
The ascent of sap occurs between the root which is the region of the positive pressure as well as the shoot which is the region of the negative pressure.
The upward movement of the water is due to the strong forces of attraction between the water molecules which cannot be broken easily. This is called as force of cohesion. There exists a force of adhesion between the water as well as the walls of the xylem. These two forces are responsible for the continuous movement of sap in the xylem vessel.

Various kinds of microorganisms have various sorts of cell walls. Some have thicker walls, while others have more slender walls with an extra external layer. Microscopic organisms with thicker walls are more delicate to penicillin since it can undoubtedly get inside and assault.

The primary functional difference between mitotic anaphase and meiotic anaphase II is the number of chromosomes that are separated. In mitotic anaphase, the chromosomes in a cell are duplicated and then separated equally into two daughter cells, so each daughter cell receives the same number of chromosomes as the parent cell. In meiotic anaphase II, the chromosomes are separated into four daughter cells, but the number of chromosomes in each cell is not the same as in the parent cell. Instead, the chromosomes are randomly divided among the daughter cells, leading to genetic diversity in the offspring
