Explain in detail the process of digestion and absorption that occurs in the small intestine. Provide a detailed description of how different types of nutrients are taken up by intestinal epithelial cells that line the gut. How does the brush border behave for different types of nutrients and how are they transported to the liver and the bloodstream following absorption?
Answers
Answer:
I believe that passive diffusion is the process in the small intestines that requires a carrier and energy to transport nutrients into absorptive cells. It usually involves the movement if the molecules from a region of high concentration to a region of low concentration through a membrane.
Explanation:
Intestine epithelial is known as the single cell layer which helps in the formation of the luminal lining of the large and small intestines of the gastrointestinal tract. It is made up of simple columnar epithelial cells. Two important known function of the epithelial cell is :
1) Absorbing necessary substances in the body such as nutrients.
2) Restricted the entry of substances which is harmful for our body.
As the nature of its protective role, the intestinal epithelium helps in the formation of important component of the intestinal mucosal barrier.
The absorption of nutrients takes place by diffusion through the small intestine's wall.
Some of the nutrients that the small intestine absorbs include lipids, proteins, carbohydrates, vitamins, proteins, etc. The inner wall of the small intestine is lined with epithelial tissue.
In the small intestine, there are epithelial cells and they help increase the amount of surface area that is available for nutrient absorption.
The absorbed nutrients are then transported through the blood vessels to the organs in the body. They're then used in the building of complex substances that the body needs.
In conclusion, the food that remains undigested will then be sent to the large intestines.

A scientist found that a Petri dish from an experiment had not been cleaned several days earlier. In the dish, she discovered a bacterial culture that she had not seen during the experiment. How could she gather evidence to support a claim about whether the bacteria had developed from the material left from the earlier experiment? a)Take a sample of the bacteria and grow it in an incubator. b)Gather dirty Petri dishes from other labs to see if they grow the same bacteria. c)Check all the clean Petri dishes for residue from the previous experiment. D)Try the original experiment again, do not clean some of the Petri dishes, and see if the bacteria grow.
Answers
Answer:
D
Explanation:
The best way she can gather evidence to support a claim of the bacteria developing from the material left from the earlier experiment would be to repeat the original experiment again, leave some of the Petri-dishes uncleaned, and then see if the same bacteria would grow on the uncleaned Petri dishes.
If indeed the bacteria developed from the material left from the earlier experiment, the same bacteria should grow on the uncleaned Petri dishes in the second experiment. If they do not grow, it means that the source of the bacteria is from somewhere else within the lab.
The correct option is D.

C. It produces nitrogen compounds that humans can breathe.
D. It converts nitrogen into a form that humans can obtain by absorbing it through their skin.

The nitrogen cycle is important to humans in the following way: it converts nitrogen into a form that humans can obtain by eating other organisms (option B).
What is the nitrogen cycle?Nitrogen cycle is the natural circulation of nitrogen in a series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.
During the nitrogen cycle, atmospheric nitrogen is converted to nitrogen oxides by lightning and deposited in the soil by rain, where it is assimilated by plants and either eaten by animals (and returned as faeces) or decomposed back to elemental nitrogen by bacteria.
The usable form of nitrogen that is assimilated by plants becomes accessible to humans when they consume the plants, hence, depicting the importance of the nitrogen cycle.

Varicella Zoster is an infectious viral disease causing chickenpox in children and shingles in grown-ups. Inoculation plays a crucial part in avoidance and lessening complications.
Aspeech on Varicella-ZosterWomen and noblemen,
Nowadays, I would like to examine a vital and predominant viral disease known as Varicella Zoster. Varicella Zoster, commonly alluded to as chickenpox, is caused by a varicella-zoster infection. It fundamentally influences children, but can too affect grown-ups who have not been already contaminated.
Varicella Zoster presents as a profoundly infectious sickness characterized by a particular hasty, fever, and common disquietude. The infection spreads through coordinated contact or respiratory beads, making it effortlessly transmissible inside families and communities.
Whereas chickenpox is for the most part a gentle ailment in children, it can lead to more serious complications in grown-ups, pregnant ladies, and people with debilitated resistant frameworks. These complications incorporate pneumonia, bacterial contaminations, and in uncommon cases, neurological complications such as encephalitis.
Luckily, the improvement of a profoundly successful antibody has essentially diminished the frequency of Varicella Zoster around the world. Immunization not as it were secures people from the distress and potential complications of chickenpox, but too makes a difference anticipate the infection from spreading inside the community.
In any case, Varicella Zoster doesn't halt at chickenpox. Once the introductory contamination settles, the infection remains torpid inside the body and can reactivate a long time afterward, causing a condition known as herpes zoster, or more commonly, shingles.
Shingles are characterized by a difficult hasty that ordinarily happens in a single dermatome, regularly along the middle or confront. The reactivated infection can cause critical pain and inconvenience, enduring for weeks or indeed months. Moreover, complications such as postherpetic neuralgia, a persistent torment disorder, can happen, especially in more seasoned people.
To combat the chance of shingles, an isolated antibody called the shingles antibody or herpes zoster immunization has been created. This antibody not as it were makes a difference anticipate shingles but moreover diminishes the chance of postherpetic neuralgia.
In conclusion, Varicella Zoster, enveloping both chickenpox and shingles, could be a viral contamination that has critical suggestions for open well-being. We have made significant progress in reducing the burden of this disease through extensive vaccination efforts.
In any case, ongoing efforts to prevent Varicella zoster from returning to our communities and to protect powerless populations require prompt attention and vaccination.

What is the mechanism by which cells are able to discriminate between self and non-self antigens and activate an immune response only against non-self antigens?
Answers
Answer:
T and B cells are able to distinguish lol
Explanation:
Answer:
The mechanism by which cells are able to discriminate between self and non-self antigens is known as self/non-self recognition. This process is achieved through the presence of special immune system cells, known as T and B lymphocytes, that have receptors on their surface capable of recognizing specific antigens. T and B cells are able to distinguish between self and non-self antigens through the process of clonal selection, where only the T and B cells with receptors capable of recognizing non-self antigens are activated and undergo proliferation to mount an immune response against the invading pathogen. This process helps to prevent an immune response against the body's own tissues, and ensures that the immune system only targets invading pathogens.
