Answer:
Immune responses to antigens may be categorised as primary or secondary responses. The primary immune response of the body to antigen occurs on the first occasion it is encountered. Depending on the nature of the antigen and the site of entry this response can take up to 14 days to resolve and leads to the generation of memory cells with a high specificity for the inducing antigen. The humoral response, mediated by B cells with the help of T cells, produces high-affinity and antigen-specific antibodies. This is in contrast with the CD8 T-cell response which leads to the generation of large numbers of antigen-specific cells that are capable of directly killing infected cells. Antigen-specific CD4 T cells, which provide help to B cells in the form of cytokines and other stimulatory factors, can also be expanded upon antigenic stimulation.
The secondary response of both B- and T cells is observed following subsequent encounter with the same antigen and is more rapid leading to the activation of previously generated memory cells. This has some quantitative and qualitative differences from the primary response.

H.L is a 65-year-old Caucasian male diagnosed with Hodgkin’s Lymphoma (NHL) 4 months ago. He just finished receiving his third of six chemotherapy courses 5 days ago. Yesterday morning, he was seen at his oncologist’s office for malaise, muscle weakness, and palpitations. He had splenomegaly on examination. A computerized tomography (CT) scan of the abdomen showed metastatic disease in the liver and spleen. He is admitted to the hospital with progressive disease. The physician confirms a diagnosis of acute tumor lysis syndrome (TLS) and writes a number of orders for H.J.
Required:
What major complication of TLS is H.J. at risk for and why?
Answer:
The correct answer would be - renal failure, kidney stones, uric acid neuropathy and other complications.
Explanation:
The symptoms of H.J include decreased urine output, flank pain, peripheral edema. H.J. is at risk for acute kidney injury which can result in renal failure due to elevated levels of uric acid, BUN, and creatinine.
Uric acid begins to precipitate in the kidneys and leads to conditions such as uric acid nephropathy and subsequent kidney injury. ECG shows in such patients as elevated heart rate due to hyperkalemia and hypocalcemia.
- Muscle cramps, Diarrhea, Nausea, and vomiting
- Renal failure due to kidney stones because of high uric acid.

Answer:
The correct answer is - stem cells.
Explanation:
Stem cells can give rise to all tissues and organs in the body. These cells can differentiate into any form of cells, which allows them to repair tissues that have been damaged by various physiological or natural ways
There are two types of stem cells: Adult Stem Cells and Embryonic stem cells.
Cells that are present in the bone marrow or umbilical cord of a newborn baby and can be divided as Hematopoietic, a cell that can form blood cells and the immune system, and mesenchymal that form the body's cartilage, bones, muscles and other.
Embryonic stem cells are found on at blastocyst stage of embryo. These cells can transform into any type of tissue in the human body, which increases their treatment potential.

Anyone know the answer?
Answer:
the answer c. is correct
Explanation:
During DNA replication, the two parental DNA strands must be separated so that both strands can be copied. The resulting structure known as 'replication fork' is generated by helicase enzymes that break hydrogen bonds that hold DNA strands together, thereby the two strands of the DNA double helix uncoil at a specific location called the origin. DNA replication always proceeds in 5' to 3' direction. In consequence, a new DNA strand referred to as 'leading strand' is continuously synthesized because this strand grows in the same direction (5' to 3' direction) of the replication fork's movement, while other new DNA strand referred to as 'lagging strand' is synthesized discontinuously in short pieces called Okazaki fragments.

Primary sensory afferent axons have widely varying diameters, and their size correlates with the type of receptor to which they are attached. Write down the axons that are the smallest and the slowest?
Answer:
Smaller and slower axons are those related to temperature, itching and pain.
Explanation:
As you may already know, the axon is an extension of the neuron that has the ability to transmit signals to cells, indicating the nerve impulse that must be felt by the body. In other words, the axons receive a synapse, which is the nerve impulse, and pass this message on to a nerve cell to turn it into a sensation. These axons have varying diameters and the speed at which they transmit messages also varies. According to researches, the smaller and slower axons are those related to the sensation of temperature, itching and pain.

occludin
Answer:
- The blood brain barrier is a layer of cells lining the blood vessels within the brain, acting as a filter that controls the molecules that pass between the blood and the brain.
- An organism's gut microbiota is the collection of all the microorganisms (e.g. bacteria, phages, fungi) that live inside the digestive system of that individual.
- A gap junction is a type of intercellular protein connection between animal cells that prevents leakage of materials through the space between the cells.
- The transmembrane protein occludin is one of the component proteins of a tight junction.
- Germ-free mice lack all microorganisms in their digestive systems, a state achieved by delivering them through cesarean section and raising them in sterile incubators.
- Pathogen-free mice are raised under sterile conditions to limit their exposure disease-causing microorganisms.
Explanation:
The blood-brain barrier is a layer of cells made up of endothelial cells that act to limit the passage of substances from the bloodstream in a more selective manner than endothelial cells of capillaries located in other parts of the body. Gut microbiota can be defined as all the microorganisms (i.e., bacteria) inhabiting the mammalian gastrointestinal tract, which helps to ferment non-digestible substrates (e.g., dietary fibers). A gap junction is a class of cell junction that is formed between cells contacting each other which allows small molecules (e.g., water, ions, metabolites, microRNA sequences, etc) to pass through this intercellular communication. In vertebrate animals, cell junctions can be divided into 1-gap junctions (communication between cells), 2-tight junctions (occludin junctions), and 3-adherens junctions, hemidesmosomes and desmosomes (anchor junctions). Tight Junctions are composed of multiple proteins including transmembrane proteins such as occludin, tricellulin, junctional adhesion molecule (JAM), and one member of the claudin protein family. Germfree animals are research animals that have no microorganisms living in or on them, which are housed in controlled/isolated conditions to prevent any type of contamination. Finally, pathogen-free animals are research animals that are guaranteed to be free of particular pathogenic (harmful) microorganisms.

What is biodiversity?Biodiversity is a word used when all the different varieties of life forms, therefore, animals, microorganisms, and plants all come together and work. both biotic and abiotic factors are included in biodiversity. There can be a variety of species that co-exist altogether.
There are three levels of biodiversity species diversity, ecosystem diversity, and genetic diversity. Examples are pine trees, sunflowers, blue whales, tigers, and all types of microorganisms. The threats to biodiversity are an invasion of alien species and an increase in the number of predators.
Therefore, biodiversity is all species coexisting altogether.

In the food web above, if new species of insect were introduced that fed primarily on plantains, how would the following populations be affected? Indicate your answer by increase , decrease or no change and include a brief explanation of your reasoning.
A) greenfly
B) rabbit
C) fox
Answer:
This is a 50/50 answer. I believe it would be fox, sorry if this is incorrect.
Answer:
Greenfly- no change
The greenfly would remain unaffected because it doesn’t rely on plantains.
Rabbit- decrease
The rabbit relies on plantains as food so more competition would result in a decrease in the rabbit population
Fox- decrease
Lesser food means lesser foxes. The foxes prey like the rabbit and mouse eat plantains. If the mouse and fat population goes down so would the fox population.
As a general rule, should sample turbidity corresponds to sample fluorescence in liquid E.coli cultures?
Answer:
Throughout the explanation segment, the description of the query is presented below.
Explanation:
The turbidity spectrometer depending on the intensity isn't a trustworthy indication of microbial cell numbers. However, these should still be utilized as parameter estimates instead of the exact numbers.Benefits at all from the measurement of the radiation reflected by both acutely and chronically organisms, since adsorption capacities change as a result of the current microbiological composition.What are altitudes? help pls
