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.
We are running a gel on the products of a restriction digest to determine the size of an insert. We know the vector backbone size should be ~2.9kb; however, the standard appears to be running too qu
During inhalation, your alveoli expand; creating a pressure difference between the atmospheric pressure and our lung sacks and therefore air will flow into the respiratory airways.
If it were possible to live forever, would our brains grow infinitely with the number of memories that we store?
For some structural study I am looking for cyclodextrin strucutures (in 3D format such as pdb, mol2, etc) complexed with small molecule ligands, such as cholesterol and even smaller.
