If someone received a vasectomy against their will while under anesthesia, how hard would you have to ejaculate to force the correct anatomic path again?

I has doing stuff on the pc at my place of residence and heard a noise from the next room. It sounded like an x ray gun or something I thought. I turned towards the sound and noticed it went off again. This time as it went off it felt like it hit my right eye dead in the middle. the reaction to this right afterwards felt like a forced emotion of anger that did not come from myself. What would this be? Edit: Also I had a look in the mirror for anything and noticed one pupil (the right eye) was larger than the other but from how the lighting was ???

How does human body produce telomerase?

Hi, I'd like to know if plants can take in sugar through the roots ? I'm doing some simple in-vitro experiments with orchids. I follow some procedures without really understanding why. Table sugar is used as an ingredients and those orchid seeds grows in the medium. Sugar is said to be a carbon source. do you know how the orchid protocorms takes in the sugar ? For plants grown in the soil or pots, is it possible for roots to take in glucose, carbohydrates, polysaccharides ( complex sugars?) and molasses directly ? Thanks.

T/F, flea cant live on the body of horses?

The "fleas" caused a lot if troubles in history.

which meat is more likely to have parasite, beef, lamb or Pork?

Most of them are sea animals, sponge, Coral, sea anemone . Any others?

i mean can you run fast with feet and hands like an animal? because in movies and cartoons humans run like a dog or somthing but would our spine not allow that? just want an opinion maybe with practice?

cats don't, so they have better vision.

Is it because the thinner skin?

Hi I was wondering if anyone could tell me about GFP extraction and alteration? I'm looking to start a project and would be willing to pay if someone could run me through the minute details of it and the process of extraction.

I think not. Someone said they do have.

In this video it is mentioned that food scarcity influences the gender of a newborn child (skip to 1:27). How can we possibly know that this is the cause?

PBS produced a show i saw last night discussing what they called Lazarus Taxia. Animals long thought to be extinct but then unexpectedly found. They suggested that the coelacanth would be an example of this phenomena. One of the reasons given is that some species simply become too rare or live mostly in environments that do not produce fossils with any regularity. A cambrian creature known as Anomalocaris has been found to have survived into the Ordovician seas from the Cambrian and was first only found in the Burgess Shale and thought to have become extinct during the Cambrian. https://en.wikipedia.org/wiki/Anomalocaris . The reasons this happens is due in part to …

Why does RFLP precede sequencing in terms of comparing similarities among rRNA genes?

I came across this perspective when I realize using the CRISPR gene editing technology in the context of synthetic biology is basically doing code/DLL injection. In another way of seeing it, it is akin to installing chrome extensions (though this isn't really accurate because chrome extensions requires explicit permission, but this will be an easier example to use than a computer virus) to add or modify functionality of chrome. Chrome extensions are able to modify and monitor everything you do in the browser, and with what genes we have designed and inserted into the genetic host, we can do something similar. This got me thinking if a new perspective can be drawn to …

If blastema formation is the key for lizard regeneration, if I am able to induce blastema formation in any part of the lizard's body, does it mean it could regenerate any part?

I'm curious as to know when is this technology available. That and it comes in two forms, injection or pill. Just like how our body ages due to the hormone(cell signaling molecules) inside the blood stream that upshifts or downshifts the gene expression. We counteract with our own artificial cell signaling molecules to downshift or upshift this particular gene expression back to its place. Long story short, by enabling the Yamanaka factors(transcription factors) with the cell signaling molecules to express these genes for a few days we could theoretically rejuvenate our cells to a younger age. We probably can't jump our age from 80 to 6, but we could go from 80 to 30…

It is a common event to be watching a fictional event where the medical person/EMT/Doctor/Nurse tells the patient to stay awake when they are bleeding to death. Question: Does that really make any difference? It seems logical that the point where there is not enough blood left to support life is the point where the body will die whether or not the person is awake or not. So, is it just theater, or not? If it is a factor, please explain the biological means/reason that it would prevent death.

When a neurotransmitter binds to a postsynaptic receptor, but either isn't a strong enough EPSP or is canceled out by an IPSP it won't create an action potential. What is the point of these neurotransmitters if they do not accomplish the action potential?Thanks!

Hello, I'm new to this forum. I'm not a Biology student, but I want to learn the science on my own. I'm interested mainly in Cellular Biology, Biochemistry, Genetics, and Evolution. In my research, I've found some good websites, textbooks and this forum. Anyone know some good resources that I can use to help me study these concepts? Textbooks, books, websites, magazines, forums, anything really. Aside from resources, how does one go about doing their own experimentation. I spoke to a Biology student and they recommended observing living organisms and studying them considering there are some organisms we know little about. They also recommended micros…

If you think about it, rapidly adapting species are the most cancerous. Or am I getting it all wrong?

So I was curious to learn more about the root systems in plants and I figured I'd make a general thread about it but I do have one question. Can plants grow more than one tap root?
