One function of the immune system is to attack the foreign cells to protect the body. In organ transplants, how does the immune system take the new organs?

Answers

Answer 1

Answer:

Answer:

it depends

Explanation:

it it would depend on the blood type or ABO compatibility and if it was the wrong blood type do it attack each other and the person would get sick. but if the blood type matches there is another reason that it may or may not take. that would be called the major histocompatibility complex or MHC. this is basically proteins called cell surface proteins. these proteins are basically the body's way of classifying cells that are of self or non-self. the t cells from an adaptive immune system will look at the MHC and determine whether or not it's for if it's foreign it kills it. if the cell "looks like it belongs ( has compatible blood type and MHC ) then it accepts the transfer.

Answer:

True

Explanation:

A law in science is a generalized precept to describe a body of conclusions in the form of an oral or mathematical description. Scientific laws (also known as natural laws) refer a cause and effect among the observed elements and must perpetually implement supporting the same situations.

True, it does so by explaining the conditions for the reaction to happen.

Which following processes can occur in the absence of oxygen? Glycolysis, Krebs cycle, the electron transport train, or the generation of carbon dioxide from Peruvian acid

Answers

Well,

Glycolysis does not require oxygen. In glycolysis, a glucose molecule is broken down into pyruvic acid and some other molecules. No oxygen is added to make the reaction happen.

Therefore, the answer is glycolysis.

What is the purpose of mimicry?a. It helps an animal evade predators.
b. It allows an animal to fit in with a different species.
c. It helps an animal to catch prey.
d. All of the above

Answers

Answer:

d. All of the above

Explanation:

Mimicry refers to the resemblance of organisms of two different species with respect to structural, behavioral or physical features. Mimicry helps a defenseless species (mimic) to protect itself against predation due to its resemblance to the aggressive and dangerous species (a model).

For example, harmless king snake mimics venomous coral snake to avoid the predators. It represents the Batesian mimicry.

In other cases, predators may use mimicry to catch their food organisms. In Mullerian mimicry, two or more harmful species resemble each other.

An organism's capacity to mimic another organism, item, or environmental aspect is known as mimicry, hence option D is correct.

Predator avoidance: Some animals imitate the looks of other, more deadly species to frighten off predators. For instance, the viceroy butterfly imitates the poisonous to predators monarch butterfly.

Adapting to a different species: In order to blend in and avoid being noticed, some animals mimic the look of other species. For instance, the peppered moth imitates lichen-covered bark to help it fend off predators.

Catching prey: To draw in prey, several creatures replicate the appearance of food. The angler fish, for instance, employs a bioluminescent bait to entice small fish.

Thus, option D is correct.

A teacher makes the analogy that stem cell research did for medicine what the Internet did for communication. What is meant by this analogy?

Answers

Internet has changed the nature of communication, making one kind of communication faster, more efficient and more universal (international). However, people find some aspects of Internet as a communication medium controversial, as they say that it stops people from interaction face to face.

Similarly,
Stem cell research has changed the nature of medicine, making one kind of research in medicine faster, more efficient and more powerfull. However, people find some aspects of stem cell research controversial, as they say that involves experimenting with human embryos.

If I were to summarize, I would say that both stem cell research and Internet introduced a step in a new direction, one that is very prolific and will likely develop further.

Answer:

B. Stem cell research led to a huge leap in medical science.

Positive feedback is most like _____.

In an unfortunate accident, a young man is struck in the leg by a bullet that tears through an artery just above his right knee. The subsequent blood loss leads to a rapid drop in blood pressure. Receptors in the aorta monitor blood pressure and send signals to the vasomotor center of the brain. In this case, the vasomotor center will increase its stimulation of smooth muscle in the blood vessels, which will cause them to constrict. This constriction leads to an increase in blood pressure. What represents the effector in this feedback system? A) blood vessel diameter B) receptors in the aorta C) vasomotor center D) blood pressure

Is Pluto a solid, gas, liquid?

a. Discuss one situation when you would use wormbase first? b. Discuss one situation when you would use OMIM first? c. Discuss one situation when you would use BLAST first? Disease: Bipolar Disorder 1. In order to find the genes influencing this disease or condition, which database would you use first? We used: NCIB, OMIM, Wormbase, BLAST. 2. Approximately how many genes (or DNA elements) are involved in this disease or condition? Explain how you came up with this number 3. Provide the genetic symbol of one of the protein-coding gene involved in this disease or condition. Explain how you know this gene is a protein-coding gene. 4. What is the cytogenetic location of this gene in Question 3? Explain what this location means. 5.What is the function of the protein coded by this gene in question 3? 6. All human diseases and traits are polygenic. Explain what "polygenic" means in this context. 7. Explain how you could find out if C. elegans has a protein similar to the one in Quesion 5? If you know the location or the OMIM# of Bipolar Disorder I can figure out the all the questions. I can't find the Bipolar Disorder OMIM and also correct for wormbase.
