What happens on a cellular level during a organ rejection? Simplified.
Organ rejection takes place when your body is subjected to a new organ which is a foreign object and attacks it.
What do you mean by Graft rejection?Graft rejection may be defined as a process in which a transplant recipient's immune system attacks the transplanted organ or tissue.
Xenograft shows high rejection. This is because it involves the transplantation between genetically distinct members of different species.
The process of organ rejection is initiated by T cells which perform the role of the recognization of a transplanted organ.
If these T cells are activated, it may lead to organ rejection by undergoing clonal expansion, and differentiation of the effector cells, which together lead to the obliteration of the tissues.
Therefore, organ rejection takes place when your body is subjected to a new organ which is a foreign object, and attacks it.

Which three careers use technologies that apply the Doppler effect?
A. Doctor specializing in circulation
B. Military
C. Restaurant worker
D. Meteorologist
Answer:
Doctor specializing in circulation, meteorologist , military
Explanation:
The three careers that use technologies that apply the Doppler effect are: doctor specializing in circulation; military; and meteorologist, which are in options A, B, and D, respectively.
What is the Doppler effect?The Doppler effect is a phenomenon that occurs when there is a change in the frequency of a sound wave due to the relative motion between the source of the wave and the observer. The Doppler effect can also be observed with other types of waves, such as light waves, and is used in a variety of technologies to measure the speed, direction, and velocity of objects.
Hence, three careers that use technologies that apply the Doppler effect are: doctor specializing in circulation; military; and meteorologist, which are in options A, B, and D, respectively.

Some amino acids are both glucogenic and ketogenic. Explain the difference between the two types and why some amino acids can be both g
Answer:
From the point of view of the type of molecule that is obtained after the degradation of the hydrocarbon skeleton, amino acids can be classified as: glucogenic and ketogenic. The main difference between glucogenic amino acids and ketogenic amino acids is that glucogenic amino acids can be converted to pyruvate or other glucose precursors, while ketogenic amino acids can be converted to acetyl CoA and acetoacetylCoA.
Explanation:
Glucogenic amino acids are amino acids that break down to pyruvate, alpha-ketoglutarate, succinyl Co-A, fumarate, and oxaloacetate and are so named because the synthesis of glucose from these molecules is feasible. Both pyruvate and the Krebs cycle intermediates noted above can be converted to phosphoenolpyruvate and subsequently glucose through gluconeogenesis.Ketogenic amino acids are the amino acids that generate acetyl-CoA or acetacetyl-CoA and are called by this name because they can cause ketone bodies. Since mammals lack the proper enzyme system, these compounds can never be used as precursors for glucose biosynthesis. Of the twenty universal amino acids, fourteen are purely glucogenic and two are purely ketogenic (leucine and lysine). The remaining four (isoleucine, phenylalanine, tryptophan and tyrosine) are glucogenic and ketogenic simultaneously since a part of the hydrocarbon skeleton originates precursors for the biosynthesis of glucose (pyruvate or Krebs cycle intermediates) and the other part acetyl-CoA or acetacetyl -CoA.

As Betty waits, she counts the number of waves that pass her during a 10-second period; she counts just 1 She estimates that the distance between crests is 6 meters. Betty sees the perfect wave and begins paddling. She pushes herself up, stands on the surfboard and rides the wave all the way in to shore, a distance of about 60 meters. It takes her about 10 seconds to ride the wave in. Use two methods to calculate the speed of the wave based pn the information presented. Are they the same? Explain how you got your answers.
Answer: 1. 0.6 m/sec. 2. 6m/sec
Explanation:
Frequency = 0.1/sec wavelength = 6 m
speed = freq x wavelength = 0.6 m/sec
speed = distance/time = 60/10 = 6m/sec
What are the charges both inside and outside of the neuron before you click the stimulate neuron button?
Answer:
The charges inside and outside of the neuron before receiving a stimulus are negative and positive, respectively, which corresponds to the transmembrane rest potential.
Explanation:
Neuron is the specialized cell of the nervous system in charge of transmitting electrical impulses. The generation of a nerve impulse in the form of an electric current is due to a change in the transmembrane potential.
Outside the neuron cell, electrical charges are predominantly positive, and the ion with the highest concentration is sodium. In the intracellular space, a great quantity of proteins provide negative charge, and there is a predominance of potassium ions. Under these conditions, the ionic channels are closed.
For this reason, a neuron at rest, before receiving a stimulus, presents positive charges on the outside and negative charges on the inside, and the membrane potential in this condition is estimated at a value of -65 mV.
Once a stimulus is produced, the ionic channels open and Na+ ions enter the cytoplasm, exchanging them for K+, which implies a change in the membrane potential which, on reaching the threshold, produces an action potential and the nerve impulse is produced.

Answer:
1. Uracil
2. Ribose
Explanation:
DNA and RNA are both types of nucleic acids. Although they are made up of similar constituent molecules, they are slightly different. All nucleic acids have three major constituents viz: nitrogenous base, pentose sugar and phosphate group.
The four nitrogenous bases found in DNA are Adenine, Guanine, Cytosine and Thymine. However, three of this bases are found in the RNA molecule but one different one called URACIL, which replaces Thymine is found. Also, the pentose (five-carbon) sugar found in DNA is deoxyribose while that of RNA is RIBOSE.

A classmate tells you that comic books are full of superheroes with powers caused
by mutations. Therefore, all mutations must be beneficial. Decide whether or not you agree. Write a
paragraph to argue your position regarding the benefits or harm caused by mutations.
Answer:
No because that is just one example, and a completely fictional example at that, used for entertainment.
Explanation:
Mutations could cause health problems and abnormalities that could prove fatal. Though there could be benefits, like immunities to diseases, inherited or contracted, just the opposite could happen as well. And even if some benefits could be gained, a whole new set of problems could result from that change that weren't there before.
What further evidence do we need to diagnose Elisa?
Answer:
ELISA, using excretory-secretory antigens from infective-stage larvae, is the diagnostic test of choice. In patients whose clinical signs and history suggest visceral toxocariasis, a positive Toxocara ELISA is strong presumptive evidence of Toxocara infection. A rising or falling titer with a twofold difference in a recently ill patient is consistent with visceral toxocariasis

When given an unknown bacterial sample the first step is to expand the current bacterial population. Which type of media best suites this need and Why
A. MSA agar
B. LB media
C. MacConkey agar
D. Columbia CNA agar
Answer:
The correct answer among the given options is - LB media
Explanation:
The type of bacteria is unknown so can not be determined precisely what media should be best for such population however, on the given information the best media would be LB media for this population due to the fact that all other media forms that are selective will inhibit its growth and it is a nutrient-rich medium which favors the growth of bacteria.
Hence, the bacteria population should be placed in LB media for growth and after expanding its growth one should place in its selective media plate.
