A penicillin reaction is a life-threatening event. In those who are allergic to penicillin, the drug acts as a __________ that binds to blood proteins, causing a strong immune response.
Answers
Answer:
A penicillin reaction is a life-threatening event. In those who are allergic to penicillin, the drug acts as a hapten that binds to blood proteins, causing a strong immune response.
Explanation:
Low molecular weight chemicals can bind to antibodies, but cannot activate B lymphocytes by themselves (they are not immunogenic). To generate specific antibodies to these small chemicals, immunologists typically bind them to macromolecules prior to immunization. In these cases, the chemical is called a hapten. Penicillin G is a typical hapten that tends to covalently bind to lysine residues both in solution and in protein-bound cells. Penicillin is a drug that behaves as a hapten, since the beta-lactam ring under physiological conditions opens and reacts with the lysine residues of proteins, forming a complex that is the main antigenic determinant of penicillin and other beta-lactams and is capable of to stimulate responses mediated by antibodies or by T cells.

A. 8.9 × 10^3 M-1s-1
B. 8.9 × 10^2 s-1
C. 1.1 × 10-10 s-1
D. 8.9 × 10-5 s-1
Answers
Answer:
D
Explanation:
From the information given:
Association rate [tex]K_a[/tex] = [tex]8.9 \times 10^3 M^{-1}s^{-1}[/tex]
dissociation constant [tex]K_D[/tex] = 10 nM
dissociation rate [tex]K_d[/tex] = ???
Using the following relation from equilibrium dissociation constant to determine the dissociation rate, we have:
[tex]K_D =\dfrac{ K_d}{K_a}[/tex]
[tex]K_d = K_D \times K_a[/tex]
[tex]K_d =(10*10^{-9} \ M) \times (8.9*10^3 \ M^{-1}{s^{-1})[/tex]
[tex]\mathbf{K_d =8.9*10^{-5} \ {s^{-1}}}[/tex]

g 33. Humans are bipedal omnivores (we eat both meat and plants, and we walk upright.) What features of the skull reflect this
Answers
Answer:
Since Skull is the most complete fossil, the features of the skull that reflects Humans as bipedal omnivores are: The teeth and the foramen magnum.
Explanation:
Humans are bipedal because they can move with their two legs, and they are omnivores because of their ability to eat both meat and plants.
The teeth on a skull are the most important indicators of what an animal eats, and it even shows if an animal is a predator or prey. Humans have different sets and shapes of teeth for different purposes making them an example of heterodont dentition.
The pelvis, knee, and foot bones should be the best to tell us about how an animal moves, however, the foramen magnum which opens for the spinal cord to pass to the brain, could also show whether how the animal moved.

Note that arteries have a thicker middle layer of tissue than veins. Why is this important and how does it affect the structure of the artery as compared to the vein?
Answers
Answer:
The correct answer is - To withstand the high pressure of the outflow of blood from the Heart.
Explanation:
The heart pumps blood to different body parts at high pressure so that it can easily reach all the parts of the body quickly. To able to hold the pressure of the blood pumped at high-pressure arteries need thick walls.
This pressure can be experienced as pulse and which required the walls of arteries and the middle layer or the tunica media to make it much thicker in arteries than in veins. In veins pressure caused by blood is very low pressure that allows them to be thin walls.

What could be the reason for this? What should be changed in their diet?
I already know this answer, just checking, it's cuz of roughage
Answers
Answer:
yes your answer is correct
Explanation:
Constipation happens when the colon absorbs too much water, this can occur if the muscles in the colon are contracting slowly or poorly, causing the stool to move too slowly and lose more water. As meat need much water to digest, so they leads to problem of constipation. Hence, they should eat sufficient amount of water to cure constipation.
Constipation is common among people in western countries who eat more meat and processed food because there is no enough roughage in their bodies which prevents constipation .Fruits and vegetables like like corn etc contains lot of roughage.

You are a well-trained Cytogenetic Technologist. You work as a Genetic Counselor at a medical institution. You are meeting a nervous couple in your office, who recently found out that they are going to be first-time parents. They have come to you to discuss the chances of having a child with birth defect or genetic disorder. To ease their nerves, you greet them with a smile in your white coat, guide them to their seats, and slowly go through the options of prenatal tests available for them.
KARTOTYPE TEST METHODS
First you introduce to the parents the importance of karyotype test, by describing its domy to detect two broad categories of abnormalities in chromosomes, (1)_____and (2)_____. You provide a few examples of genetic disorders that can be caused by chromosomal abnormalities, such as (3)____and (4)____. Some parents would like to know what is the main cause of these genetic disorders. Without going into too much detail, you explain to them that chromosomal abnormalities are usually caused by (5)____in meiosis I and melosis II, when the homologous chromosomes or sister chromatids fail to separate during meiotic cell division
After the parents have decided to conduct a fetal karyotype test, you collect a small sample of chorion cells through chorionic villi sampling (CVS). Chorion is a membrane around the embryo that eventually fuses with the amnion. The chorion cells are grown in culture because chromosomes are most visible at (6)___stage of cell division. You use a technique called banding to create distinguishable landmarks on the chromosomes. There are several types of staining techniques you can use for karyotyping, some advanced techniques like FISH (fluorescent in situ hybridization) uses fluorescent probes to add colors onto different DNA sequences on the chromosome. You choose the most common type of staining techniques called G- banding to label the fetus chromosomes with Glemsa dye.
After taking photos of the chromosomes from a microscope, you sort the (7)____pairs of autosomes in the following order, from (8)____to (9)____, and keep the sex chromosomes last. The sorted photographed image of chromosomes is called (10)____. Now, you are ready to examine the karyotype of the fetus.
Answers
Answer:
1 monosomy
2 trisomy
3 Down syndrome
4 Turner syndrome
5 non-disjunction
6 metaphase
7 twenty-two
8 largest (chromosome 1)
9 smallest (chromosome 22)
10 karyotype
Explanation:
Non-disjunction during meiosis I or II occur when homologous chromosomes or sister chromatids refuse to separate. This makes the resulting gametes to have too many or too few chromosome numbers in their genomes.
A gamete with too few chromosome number that participates in fertilization with a normal gamete will result in a zygote with abnormally less chromosome number. This situation is referred to as monosomy. Whereas, the fusion of a gamete with too many chromosome number with a normal gamete will result in a zygote with too many chromosome, a situation known as trisomy.
The manifestation of monosomy and trisomy in humans results in Turner and Down syndromes respectively.
Humans have 23 pairs of chromosomes out of which a pair determines maleness or femaleness - the sex chromosome. Other chromosomes are referred to as autosomes. Hence, there are 22 autosome pairs and 1 pair of sex chromosome.
Chromosomes are studied by karyotyping, a process that involves photographing chromosomes at the metaphase stage of the cell cycle, cutting them out, and then arranging them in decreasing order of size.

In a diploid cell, a FISH probe should produce ____________ signals in metaphase FISH and ____________ signals in interphase FISH.
Answers
Answer: Four, two
Explanation:
FISH (fluorescence in situ hybridization) is a technique for chromosome mapping with probes that emit fluorescence and allow the visualization, distinction and study of chromosomes of nuclei in metaphase or inferophase. In this way, any type of anomaly such as inversions, aneuploidies, duplications or microdeletions can be seen. To do this, a non-specific DNA staining is performed with DAPI (a fluorophore that marks the nucleus where DNA is present) and the fluorescence will be seen under the microscope.
When cells are in metaphase, their chromosomes are condensed in preparation for cell division. To stop them in metaphase, colchicine is used which is a microtubule depolymerizing agent responsible for separating the sister chromatids of a chromosome, thus preventing the progression of cell division and arresting the cell cycle in metaphase. Here we will see translocations, microdeletions or duplications.
Interphase FISH is used to see decondensed chromatin, which allows higher resolution in detecting small abnormalities. It is mainly used for the detection of aneuploidies or large deletions, duplications or translocations when samples are difficult to grow or are scarce, as in the case of fetal or tumor cells. It is not possible to distinguish between a normal karyotype and a karyotype showing a balanced translocation. In addition, it can be used in the analysis of solid tumors, which divide very infrequently.
During metaphase, the chromosomes are duplicated so there would be two sets of chromosomes (a total of four chromosomes). Then, there would be four signals for each probe. During interphase, the chromosomes are not dupicated. Since it is a diploid organisms, there would be two chromosomes and this will represen two signals for probe.
