1) Speculate on and/or research potential mechanisms which would afford the improved processing.
While existence of the "professional" antigen presenting cells partially ameliorates problem of the self/non-self discrimination, it remains difficult to understand how it is possible that the cell's class II molecules are not deluged with the processed "self" molecules.
2) Speculate on and/or research potential mechanisms which would afford improved the processing or recognition of potentially dangerous molecules versus presumably not so dangerous self antigens.
Using this information, what two strategies can you use to isolate the giraffe's gene from its genomic library. If only females are found to be black, what were genotypes of the parents.
Dozens of potato varieties exist, differing from each other in potato-tuber size, skin colour, flesh colour, and shape. One might construct a classification of potatoes based on these morphological traits. Which of these criticisms of such a classifi..
In horse, black coat colour is influenced by the dominant allele (B) and chestnut coat colour by the recessive colour (b). Trotting gait is due to dominant gene (T), pacing gait to the recessive allele (t). What colour horse would you use to find out..
Which pair will have been likely to agree that strata such as those depicted here were deposited gradually over long periods of time by subtle mechanisms that are still at work?
The small intestine is specialized for absorption by the huge number of villi that line the intestinal wall. Villi have cells that generate intestinal enzymes which complete the digestion of peptides and sugars.
Assume you performed a gram stain on a sample from a pure culture of bacteria and observed a field of red and purple cocci. Adjacent cell were not always the similar colour. What do you conclude.
Based on what you already know about photosynthesis, develop the testable hypothesis to elucidate the influence of an increase in light intensity on the photosynthetic rate in tomato leaves.
A man with a chin dimple and a non dimpled woman produce eight children, all having the chin dimple. Can you be certain of the man's genotype? Why or why not? What genotype is more likely, and why gives reason.
Sketch a diagram that illustrates how you would expect the triglyceride and phospholipid molecules to interact with the water. Be sure to indicate structures, if any that might form as a result of these interactions.
The measurements to be comparable in both preparations. Illustrate one experiment you could perform to demonstrate such lack of equivalence of the two cells in the zygote. Noticeably state the expected outcome of your experiment in the reply you prov..
A test tube contains starch, pancreatic amylase, and water. The buriet is negative. After 30 minutes, Benedict's test is positive. What substance is present.
Evaluate and contrast the philosophies of John Locke and Charles Darwin as they relate to developmental theory. In designing the drug that would bind to the active site and jam it, researchers must use which type of molecule.
