Answer:
b. Fetal hemoglobin binds oxygen better than maternal hemoglobin because BPG is present at similar levels in fetal and maternal blood, but it binds poorly to fetal hemoglobin, causing more fetal hemoglobin to be in the R state.
Explanation:
BPG is a chemical compound which is found in red blood cells. It is known for decreasing the affinity of hemoglobin with oxygen and thus helps in unloading oxygen from hemoglobin.
Owing to the structural difference, fetal hemoglobin binds to BPG with less affinity as compared to maternal hemoglobin thus it shifts the oxyhemoglobin curve to the left i.e. causes fetal hemoglobin to be in the R state. Due to this, fetal hemoglobin can carry up to 30% more oxygen as compared to maternal hemoglobin. As a result of this, oxygen is readily transferred to fetal blood when maternal blood enters placenta which restricts hypoxia in fetus.

Which statement regarding the "Krebs bicycle" is true? A) Ultimately, it results in the transport of NADH from the mitochondrial matrix to the cytosol. B) The urea cycle and the citric acid cycle have common cycle intermediates and are thus linked. C) Ultimately, it results in the transport of glutamate from the cytosol to the mitochondrial matrix. D) It requires a set of reactions known as the aspartate–argininosuccinate shunt.
Answer:
The correct answer is option D. It requires a set of reactions known as the aspartate–argininosuccinate shunt.
Explanation:
The Krebs bicycle is made out of on the right side the urea cycle, which networks with the aspartate-argininosuccinate shunt of the TCA cycle present on the left side. By argininosuccinate lyase, Fumarate delivered in the cytosol of the urea cycle enters the Krebs cycle in the mitochondrion and is changed over in a few stages to oxaloacetate.
Oxaloacetate gets an amino gathering with the help of transamination from glutamate, and the aspartate formed and leaves the mitochondrion and gives its amino gathering to the urea cycle in the response of argininosuccinate synthetase activity.
Thus, the correct answer is option D. It requires a set of reactions known as the aspartate–argininosuccinate shunt.

The speckled chicken on the right results from a cross between a black and white chicken. Explain what type of inheritance this would be, and draw a punnett square to show how this would happen.
Answer:
- Codominance
- 100% speckled chicken
Explanation:
This gene inheritance is called codominance, where both alleles can be expressed. In these cases, heterozygote individuals instead of showing an intermediate phenotype, express both alleles. Their phenotype is an additive expression of their parents' genes.
When two individuals, homozygous for a certain trait, are crossed they produce heterozygous individuals that express both alleles equally.
A typical example of codominance is the case of speckled chicken, the product of the cross of a black individual with a white individual. Black chickens (BB) only have this gene for feather color, while white chickens (WW) only have the gene for white feathers. When they cross, their progeny will have both genes (BW), and both of them will be expressed as speckled feathers.
Cross:
Parental) BB x WW
Black White
Gametes) B B W W
Punnet square) B B
W BW BW
W BW BW
F1) 100% BW, speckled individuals.

If the Hemoccult test result is negative, no further testing is done. If the Hemoccult test result is positive, the individual will have a second stool sample tested with the Hemoccult II test. If this second sample also tests positive for blood, the individual will be referred for more extensive evaluation. What is the effect on net sensitivity and net specificity of this method of screening
Answer:
Hemoccult test sensitivity is 89.3% and specificity is 92.7%
Explanation:
Hemoccult test is a test that is carried out in order to find out the presence of occult blood in your stool. This method is used to detect colorectal cancer in your body. Blue color of the blood indicate that the test is positive while the green color represents that the test is negative. Test sensitivity is the ability of a test which identify the person who is affected with the disease i. e. true positive, whereas test specificity is the ability of the test to correctly identify the patient without the disease. The value of sensitivity of the Hemoccult test is 89.3% the specificity is 92.7%, and the positive predictive value is 2.5%.
Each of two parents has the genotype brown divided by red, which consists of the pair of alleles that determine hair color, and each parent contributes one of those alleles to a child. Assume that if the child has at least one brown allele, that color will dominate and the child's hair color will be brown. a. List the different possible outcomes. Assume that these outcomes are equally likely. b. What is the probability that a child of these parents will have the red divided by red genotype? c. What is the probability that the child will have brown hair color?
Answer:
Explanation:
From the given information:
Each of two parents has the genotype brown divided by red
So ;
The man's genotype is : [tex]\mathbf {\dfrac{Brown}{Red}}[/tex]
The woman's genotype is : [tex]\mathbf {\dfrac{Brown}{Red}}[/tex]
This [tex]\mathbf {\dfrac{Brown}{Red}}[/tex] genotype consist of the pair of alleles that determine hair color
Now; we are given an assumption that:
if the child has at least one brown allele, that color will dominate and the child's hair color will be brown.
i.e Brown allele is dominant to Red allele
(a) List the different possible outcomes.
The cross between :
[tex]\mathbf {\dfrac{Brown}{Red}* \mathbf {\dfrac{Brown}{Red}}}[/tex] will produce the following offsprings which is the different possible outcomes.
[tex]= \mathbf {\dfrac{Brown}{Brown} \ \ : \ \ \mathbf {\dfrac{Brown}{Red}} \ \ : \ \ \mathbf {\dfrac{Red}{Brown}} \ \ : \ \ \mathbf {\dfrac{Red}{Red} }}[/tex]
(b) . What is the probability that a child of these parents will have the red divided by red genotype?
The probability that the child of these parents will have [tex]\mathbf {\dfrac{Red}{Red} }}[/tex] is one out of four
i.e
= 1/4
= 0.25
(c) What is the probability that the child will have brown hair color.
We are being told that; if the child has at least one brown allele, that color will dominate and the child's hair color will be brown.
i.e Brown allele is dominant to Red allele
Thus; from above we will see that three of the offsprings have at least one brown allele;
Thus; the probability that the child will have brown hair color is = 3/4
= 0.75

45-year-old was admitted with sarcoidosis of both lungs. An extracorporeal perfusion of donor lungs, from an unrelated donor, and successful bilateral lung transplantation were completed without any complications. What is the second code you should assign
Answer:
The second code in this case is the procedure for perfusion
Explanation:
Extracorporeal perfusion is the process of diverting the patient's blood via an artificial circulatory device to enable the gas exchange (oxygen absorbed, carbon dioxide removed) to take place. Only medical experts should handle this procedure so as to avoid any and all undesired scenarios or negligence towards patient care.
The next morning your team returns to work in the laboratory, where you get a call from the sheriff. The family of the three missing boys is pressuring him for information. Your team begins the final osteological exam. After careful examination, you produce your final inventory. You are working with the same number of bones, but you now have determined which side of the body they come from (when applicable).
You have:_______.
• 3 skulls
• 6 femora (4 right and 2 left)
• 4 os coxae (All adolescent males, 1 right and 3 left)
• 2 humeri (both right)
• 2 tibiae (both left)
• 5 scapulae (3 right and 2 left)
1. Based on the revised inventory, would you change your MNI? If so, what would be the new MNI?
2. What do you tell the sheriff? Are these the missing boys?
Answer:
See below
Explanation:
1. Yes, the MNI ought to be changed in light of the revised inventory. Since 4 of the 6 femora are right sided, they would belong to different individuals, so the MNI would now be stated as 4.
2. The sheriff would be told that the possibility of suspecting 22 individuals is very narrow, though not impossible. It is also unlikely that the victims are numbered less than 4 in accordance to the bones found.

Explanation:
Macromolecules in the cell can often interact transiently as a result of noncovalent interactions. These weak interactions also produce stable, highly specific interactions between molecules. Which of the factors below is the most significant in determining whether the interaction will be transient or stable?
a) the size of each molecule
b) the number of chemical bonds between the molecules
c) the concentration of each molecule
d) rate of synthesis
Answer:
The correct answer is option b) "the number of chemical bonds between the molecules".
Explanation:
Chemical bonds are the forces that enable the formation of compounds. The number of chemical bonds is a determining factor to know if an interaction will be transient of stable. The more chemical bonds the more stable an interaction will be. Few chemical bonds between molecules makes an interaction unstable and easy to break, enabling transient interactions that are key to certain biological pathways.

BEFORE equilibrium has been reached in this container: (Circle a letter for each) 1. Movement of glucose across the membrane in this container can best be described as A. Solution A to Solution B B. Solution B to Solution A C. both directions D. neither direction
Hello. You forgot to put the image so that this question can be answered, but I will describe what the image shows.
The image shows two types of "cups" that have a type of connection between the two. In cup A there is 1 mole of glucose and 1 mole of fructose. In cup B there is 0.1 mol of glucose and 1.5 mol of fructose.
Answer:
A. Solution A to Solution B
Explanation:
Balance is achieved when the "cup" with the lowest concentration of glucose receives glucose from the "cup" with the highest concentration, to the point that the two glasses establish equal concentrations of glucose between them.
We know that cup B has a lower concentration of glucose, which indicates that the movement of this solute was from cup A towards cup B. With this we can conclude that the letter A is the correct answer.
In an accident with farm machinery, Mr. Roque had his left arm severed just below the elbow. Mrs. Roque stopped the bleeding, called for an ambulance, and packed the severed arm in ice for the EMTs to take to the hospital. Will Mr. Roque ever be able to move the fingers of his left hand again? What structures must be reattached, and what has to happen?
Answer:
The mentioned case of arm severing is considered as major surgery, and the restructuring of the severed arm is only possible when Mr. Roque will reach the hospital within four to five hours of the incident, also known as the window period.
After performing the surgery, Mr. Roque may regain movement in the arm to some extent after performing certain kinds of exercises, however, he may not feel the sensations in the fingers of his left hand again. The entire process of healing of the severity may take about two to three years, and in certain cases, the body fails to heal completely, and the affected limb may lose its function entirely.
In the given case, the structures that are required to get reattached are the muscles of the forearm and the blood vessels and the nerve supply to the affected region. The systematic arrangement of these structures is done with the help of surgery. However, after the surgery, the patient is recommended to perform certain kinds of hand and finger muscle exercises so that the functioning of the arm get regain slowly and gradually.

O AO OO M MM MN H HH Hh
O AO OO N MN NN h Hh hh
Type A- 1/2 O-1/2 type M- 1/4 MN-1/2 N- 1/4, type H- 3/4 h-1/4
Type A with M antigen:
1/2*1/4*3/4 = 3/32
Type A with M and N antigens:
1/2*1/2*3/4 = 3/16
Type A with N antigen:
1/2*1/4*3/4 = 3/32
Type O with M antigen:
1/2*1/4*3/4= 3/32
Type O with M and N antigens:
1/2*1/2*3/4 = 3/16
Type O with N antigen:
1/2*1/4*3/4 = 3/32.
The 3/4 value comes from the expression of Hh-3/4 (this determines if the A and B Angie will be expressed).

A possible explanation for the differences in structure, function, and behavior between
chimpanzees' and humans is provided by the
bota
Answer:
The theory of evolution by natural selection
Explanation:
Nowadays, it is widely accepted that chimpanzees are primates closest related to us. Darwin's postulated "The theory of evolution by natural selection", in the book "On the Origin of Species" in 1859. It is a theory that explains how species evolve over successive generations by gradual changes and the selection of the most adaptive phenotypes. Anatomical, fossil, and genetic evidence support the idea of an evolutionary link as Darwin predicted between hominids (humans) and other primates.
In regard to genetic evidence, whole-genome sequence analyses have shown that humans and chimpanzees share about 98% of sequence homology. Moreover, according to the phylogenetic tree, both species evolved from one common ancestor that was present approximately 4 million years ago.
In regard to anatomical and fossil evidence, it has been discovered that the chimp brain has a similar size to human extinct relatives, and thereby also supporting an evolutionary link between both species.
