The difference between a mutation that causes disease and one that is harmless can be used for genetic prognosis. The human recessive allele that causes color blindness and the hemophilia allele are both located on the X chromosome, 10 cm apart. Below is a pedigree. Black symbols represent individuals with haemophilia, because the individuals marked with a cross are color blind.
Answers
In the pedigree given, black symbols represent individuals with haemophilia, while the individuals marked with a cross are color-blind.
There are several variations between a mutation that causes disease and one that is harmless:
1. Effect on an organism: Mutations can have a beneficial, neutral, or detrimental impact on an organism, depending on where they arise in the genome and what the consequences are.
2. Consequence: Mutations that cause illness have a more severe effect on the body's capacity to function normally than those that are harmless.
3. Inheritance: Mutations that cause illness may be inherited or acquired, whereas harmless mutations are often present from conception and may be heritable as well.
4. Prevalence: Mutations that cause illness are rarer than those that are harmless and are often linked with familial history or an individual's genetic makeup.
To begin, color blindness is an X-linked recessive genetic disorder. As a result, women have two copies of the gene, while men have just one. The women are called "carriers" of the condition. Because the gene for color blindness is located on the X chromosome, males are more likely to be affected than females.
In the given pedigree, all the males who are black (shaded) and marked with a circle are hemophiliacs. As a result, the trait is X-linked recessive, meaning it is more frequent in males. We can also observe that the trait is not present in all generations, indicating that it is recessive and requires two copies of the mutant gene to express its symptoms. The individuals who are marked with a cross (X) are color blind, indicating that they have two mutant genes on their X chromosome. However, because the trait is recessive, they must have inherited a mutant gene from both parents.

Many marathon runners "hit the wall" around mile 20. What does this tell you about glycogen?
a. There is not enough oxygen by mile 20 to continue using glycogen.
b. Oxidative phosphorylation of glycogen is too slow by mile 20.
c. Glycogen stores are mostly depleted by mile 20.
d. Exercise intensity is too high by mile 20 to be sustained by glycogen anymore.
Answers
The fact that many marathon runners "hit the wall" around mile 20 indicates that glycogen stores are mostly depleted by that point (option c).
Glycogen is the stored form of glucose in the body, primarily found in the liver and muscles. During prolonged exercise, the body relies on glycogen as a fuel source.
However, glycogen stores have a limited capacity. As the marathon progresses, the body gradually depletes its glycogen reserves. By mile 20, the available glycogen becomes insufficient to sustain the required energy levels for the runner.
This leads to a sudden onset of fatigue, loss of energy, and a feeling of hitting a physical wall. It should be noted that the other options are not accurate explanations for hitting the wall. The issue is primarily related to the depletion of glycogen stores rather than oxygen availability, oxidative phosphorylation, or exercise intensity.

why can protein structures be more highly conserved than individual amino acid sequences?
Answers
Protein structure can be more highly conserved than individual amino acid sequences because the structure of a protein determines its function. Even if the amino acid sequence varies slightly, as long as the overall structure is maintained, the protein can still perform its intended function. This is because the structure of a protein is determined by the interactions between the amino acids, such as hydrogen bonding and disulfide bonds, which are more important for maintaining the structure and function of the protein than the individual amino acids themselves.
Therefore, the protein structure can be more highly conserved than the individual amino acid sequences because it is more important for the protein's function.

Explanation:
in the liver, the enzyme pyruvate kinase is activated by fructose 1,6-bisphosphate. explain why these regulatory mechanisms make sense.
Answers
The presence of liver pyruvate kinase, which is triggered by fructose 1,6-bisphosphate, provides a metabolic benefit. Fructose 6-phosphate is phosphorylated to form FBP, a glycolytic intermediate.
Pyruvate kinase activity is activated when FBP attaches to the allosteric binding site on domain C of the enzyme. This conformational shift is brought on by a change in the enzyme's structure.The last stage of glycolysis is catalysed by yeast pyruvate kinase (PK). As a result, the enzyme serves as a crucial regulatory point and fructose-1,6-bisphosphate (FBP) allosterically activates it. Pyruvate kinase must be deactivated during gluconeogenesis to avoid a fruitless cycle. Thus, pyruvate kinase is rendered inactive by high quantities of both alanine and ATP.

a final mrna transcript of 300 nucleotides would code for ______ amino acids.
Answers
The reading frame of the mRNA transcript and the specific codons it contains.
Each amino acid is coded for by a triplet of nucleotides (a codon), so if the mRNA transcript has 300 nucleotides, it could potentially code for up to 100 amino acids. However, there are stop codons that signal the end of the protein-coding sequence, so the actual number of amino acids encoded by the transcript would depend on where these stop codons occur.
Additionally, the mRNA transcript must undergo processing (such as splicing) before it can be translated into a protein, which could also affect the final number of amino acids in the protein.
A final mRNA transcript of 300 nucleotides would code for 100 amino acids.
1. mRNA is composed of nucleotides, which are read in groups of three called codons.
2. Each codon codes for one amino acid in the process of translation.
3. To find the number of amino acids encoded by 300 nucleotides, divide the total number of nucleotides (300) by the number of nucleotides per codon (3).
4. The result is 300 / 3 = 100 amino acids.

Place the respiratory structures below in the order that air would pass through them as it moves from outside your body to the inside of your lungs.
1.) bronchus
2.) trachea
3.) nose
4.) alveoli
5.) bronchioles
6.) larynx
7.) pharynx
Answers
The correct order of the respiratory structures as air moves from outside the body to the inside of the lungs is as follows:
3.) Nose ⇒ 7.) Pharynx ⇒ 6.) Larynx ⇒ 2.) Trachea ⇒ 1.) Bronchus ⇒ 5.) Bronchioles ⇒ 4.) Alveoli.
This order represents the path of air as it enters the respiratory system. Air first enters through the nose, then passes through the pharynx and larynx. From there, it travels down the trachea, which branches into the bronchi. The bronchi further divide into smaller bronchioles, and finally, the air reaches the alveoli, which are the tiny air sacs where gas exchange occurs in the lungs.
The respiratory structures work together seamlessly to ensure the efficient passage of air and the vital exchange of gases. From the initial inhalation through the nose to the final gas exchange in the alveoli, each structure plays a crucial role in the respiratory process, allowing for the intake of oxygen and the elimination of carbon dioxide, ultimately supporting the body's overall oxygenation and cellular function.

a particle of oxygen has 8 protons and 8 electrons. is this an atom or an ion? what's the charge?
Answers
Answer: It is Atom and the charge would be postive.
Explanation: If the atom had 8 protons and 8 electrons (oxygen for example), knocking one of the electrons out, makes 8 protons and 7 electrons. The atom now has a net charge of +1 because the 7 electrons cancil the positive charges of 7 of the protons in the nucleus, but there is one remaining proton with a positive charge.Oxygen's 8 electrons are negatively charged, and they orbit the atomic nucleus and balance the positive charge of the 8 protons. The positive charge of 1 proton exactly cancels the negative charge of 1 electron. Answer 9: Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!
