Describe the different strategies that mammalian digestive tracts use to digest different polysaccharides.
Define what the term allergy refers to. Explain the immunological mechanisms contributing to an allergic response.Outline what is meant by passive and active immunisation.
a diaphragm for light, the iris regulates how much light comes into our eyes. In bright conditions, the muscles of the iris limit how much light comes in. In lowlit conditions, the muscles of the ir
The other person said they don't. While there is something there that acts similar to a vacuole, it's slightly different. The person also noted that the only websites that say that something as a va
We cultivate a number of terrestrial organisms in greenhouses and stables where they live in completely artificial environments.
I was reading about Prochlorococcus, among other photoautotrophs, and found that they seem to get their nitrogen from ammonia, which must be produced by some other organism.
What depth penetration can one typically get with atomic force microscopes? (i.e. how far into the tissue can one image?). I have found numbers on acquisition times (minutes) and spatial resolutions
I've read somewhere that after a person has a heart transplant, it is possible that his/her attitude, action or behavior would change slightly or significantly, as though he/she possesses some aspec
I was looking at this list: Super resolution microscopy, but they don't talk about in vivo imaging.
What are the spatial (lateral and axional), and temporal resolutions that one is expected to get with the following optical imaging techniques
I'm a computer programmer deeply interested in Biology. I wish to write a computer simulation for cell differentiation. I understand there will be seemingly impossible challenges in doing this.
The scientific consensus is that no one ever fills up their memory capacity by learning facts and so on, even in the information age.
I've read that unlike humans, octopuses have eyes "designed" the "right way", i.e. with the nerve fibers behind the retina, thus getting rid of the blind spot we humans have as well as theoretically
Is there a reason as to why chickens lay "egg" shaped eggs, as opposed to spherically shaped eggs (or a random shape)?For extra points (actually just to add more words in order to meet the "quality" s
Is it possible to select from colonies only cells which are at a certain stage in the cell cycle? E.g. if I was trying to analyse expression of a number of genes during different stages of the cell
I'd specifically like to know the percentage of carbohydrates and amino acids relative to the amount that was ingested in diets of various types and amounts.
When tired and it was dark, I noticed that if I focused on a dim light source and moved my eyes fairly rapidly sideways, the resulting images that lingered for a short while were not smoothly blurre
The seeds in bush bean pods are each the product of an independent fertilization event. Green seed color is dominant to white seed color in bush beans. If a heterozygous plant with green seeds self-
A pure-breeding fruit fly with the recessive mutation cut wing, caused by the homozygous cc genotype, is crossed to a pure-breeding fly with normal wings, genotype CC .
How do bacteria exchange their genetic material? Cell differentiation is a distinct phenomenon in eukaryotic animals. Name any four kinds of differentiated cells in your body.
I've seen a patient who had a Vasectomy (eye surgery) done on a single eye manifest massive swelling on both eyelids.That seems like having my left hand swell after punching a wall with my right one.
I've seen a few talks on the subject. From a gene cluster, there is some decent ability to determine which domains contribute to certain functional groups in the final metabolites. It sounds like th
In order to survive, prokaryotes such as bacteria need to produce energy from food such as glucose. In eukaryotic cells, respiration is performed by mitochondria, but prokaryotic cells do not have
When producing insulin, the gene for its production is inserted into the plasmid of a bacterium that is allowed to replicate freely.
