| What's the difference between vitamin A, retinol, and retinoids? Posted: 09 Apr 2022 06:52 AM PDT I've been looking into skin care products and became interested in retinol for its supposed benefits. Something that's confusing for me though, is why couldn't I use pure vitamin A oil for the same purpose? It's generally only marketed as a dietary supplement, but it's often much cheaper and without all of the extra ingredients. Everything that I've read says they're basically the same, but doesn't really explain how they're different. Why couldn't I just use the vitamin A oil directly on my skin and reap the benefits without spending the extra money? [link] [comments] |
| Posted: 09 Apr 2022 09:51 AM PDT In elementary school, I was told by the teacher that canaries have smaller lungs than humans, making them more susceptible to poisonous gas but that answer never sat well with me because smaller lungs should take in less total poison dose. Also birds are smaller than humans so the poison concentration should be fairly similar on a per weight basis. The only way I could see the bird showing symptoms first is if it has a disproportionately increased respiratory and metabolic demands compared to humans, resulting in faster accumulation of poisonous gas or that poisonous gas of equivalent dose is more potent towards canaries than to humans?

| What are immunosuppressants, and are the immuno-boosters? Posted: 09 Apr 2022 03:30 PM PDT I understand organ recipients need to take immunosuppressants. How do they work? Do different people require different amounts? And is there a reverse immuno-booster? [link] [comments] |

| Why do some metals stick to surfaces why others don‘t? Posted: 09 Apr 2022 01:19 PM PDT I know that molten bismuth sticks to aluminum oxide while molten sodium forms a droplet to minimize its surface energy. I'm also aware that some surfaces are hydrophobic because they are not polar. However, this concept can't apply to metals, can it? So why do some metals stick to some surfaces well while others do not? [link] [comments] |
| Posted: 09 Apr 2022 05:25 PM PDT How do you predict the charge of a transitional metal in the product of a single replacement reaction and double replacement reaction? For example: Single replacement reactions: Fe + CuSO4 --> FeSO4 + Cu How would you know that Fe had a charge of 2+ in this case? Double replacement reactions: FeBr3 + NaOH --> FeOH + NaBr3 How would you know that Fe had a charge of 3+ in this case? Does the charge not change in double replacement reactions? [link] [comments] |
| How long do things like the common cold survive on plastics? Posted: 09 Apr 2022 10:09 AM PDT Or how long germs/colds in colder tempts? I wanna know things. People always say they lose their infection rate but it also depends on factors like this. [link] [comments] |
| Is there a way of diagnozing Schizophrenia without ever talking to the patient? Posted: 08 Apr 2022 08:59 PM PDT Neuro connectivity is affected but is there a specific part of the brain activity that can be measured to show symptoms of schizophrenia or is it strictly diagnozed after talking to a patient.

| How does long term alcohol intake cause a blockage of the pancreatic duct? Posted: 08 Apr 2022 06:02 PM PDT Pretty much as in the title, considering a functioning liver, how does alcohol affect the pancreas such that it is one of the most common causes of pancreatitis though a blockage of the pancreatic duct?

| What is the relationship between children born inside/outside marriage and fertility rates? Posted: 09 Apr 2022 08:05 AM PDT I recently encountered an opinion that a government/state should support marriages because it incentivizes pairs to have more babies. Is it so? [link] [comments] |
| What determines the lifespan of a species? Posted: 08 Apr 2022 04:52 AM PDT Why is it that humans can live up to 100, but dogs have an average lifespan of, what, 10 years? And flies/insects only live a couple of days? What determines it? Is it the enviroment or something to do with the animal's anatomy? Would we be able to increase other animals' lifespans like we did with our own? [link] [comments] |
