People often say, including those with extensive knowledge in biology, that a certain species of animal will evolve in one way or another: 1.From changing environments. 2.Mutations. 3.Possibly even genetic engineering from human animals. My question lies in the fact that, aside from the latter option, why haven’t any differences in animals'(except humans) markup, morphology,… Read More »
Should such a phobia get intensified due to neural plasticity (same neural pathways that are repeated get stronger) or should they avoid such movies/experiences to have less scary imagination?
How come men do anything to get in women’s pants? Lie, cheat, steal, kill, harm. Why do you deceive and lie to women just to fuck them? Why do they only want to just fuck women and leave them after?
I was wondering what organelles are in an onion cell, because, based on the labs we are doing in my biology class, I only saw a nucleus and cell wall. My friends and brother say there are all the organelles that you would find in a typical plant cell, but I can’t find any evidence… Read More »
In a lot of papers I am reading, people are amplifying the OmpC gene (which codes for the OmpC membrane protein), from ‘E. coli’ but they do not specify the strain they used. According to my understanding, this protein helps transport various substances across the membrane, though, it is found in all E. coli strains?… Read More »
I have been given a project involving a plasmid that contains long stretches of Adenine (60 or 120 bases each). These PolyA stretches are interrupted by the occasional G or C. I understand that performing PCR, cloning, DNA synthesis, mutagenesis, and sequencing on repetitive sequences is difficult. What techniques and practices should I follow to… Read More »
Most actual karyotypes online appear as single chromosomes (unreplicated). I was under the impression that a micrograph of the replicated chromosomes was taken during metaphase of mitosis and thus should show up as duplicated sister chromatids instead of single chromatids post anaphase. Are the arms of the chromatids just so close to each other that… Read More »
I have a question. I recently had gotten a cut behind the the top side of my lip . My wound from my accident has a pea sized bump (possibly smaller )which is very noticeable, while on the other hand my wound is white and i sappose healing ..is this bump only tempory? And what… Read More »
Why can the immune system kill its host? It is always better to just take up the insect poison, or peanut protein etc. instead to kill the host by preventing the breathing. Is it just a modern symptom or did humans always have to fear death from anaphylaxis after an insect sting?
They are both ways to measure divergence in species but I’m not understanding in what exactly the differ if both use hybrid zones and gene frequencies in the study.
