The boiling point of branched hydrocarbons is lower than the boiling point of straight chains hydrocarbons (I am talking about Isomers--> same number of Carbon atoms ) Why is this so? What does that have to do with intermolecular forces?

thanks a lot

I have a question about the occurence of meiosis. I was told meiosis occurs during gametogenesis (formation of gametes such as sperm/ova). And during meiosis 1 - prophase 1 there is crossing over occuring to create more diversity. My question is crossing over of whose chromosomes because we have 2 pairs of every chomorome (not chromatid)??? Each individual has its own set of chromosomes, I can't see how crossing over can occur during the formation of 4 sperm or 1 egg because fertilization has not occured yet. And does meiosis occur during fertilization, if yes the result would be 4 genetically distinct cells in one human being??? If no, then how can there be a genetically distinct zygote in result that has traits from both father and mother. I am not sure if the chromosomes are just mixed during fertilization (when sperm fertilizes the egg). I'm just confused, please clear that up for me. (ultimately i'm asking where meiosis occurs) Thanks in advance.

Plant cells have rigid cell walls to hold the cells together, how do animal cells hold themselves together. Does it have something to do with the chemical properties (dipoles) of the phospholipid bilayer?

Doesn't mean anything. Thats just a theory. Its like saying "If you cut a tomato without cutting it, you would become twice your size :)" Prove it

Interesting theory, but if there are no reference points..........what is expanding and what isn't? Maybe it is contracting instead of expanding? think about it. Another thing....... The relation between the distance from the body to the "expanding" object, and the "gravity force" or "how fast you are being "pulled" toward the pulling object" is not linear, it is indeed a curve. So in my opinion, your theory can't work. nice theory though

so is ice a conductor or not YT?

MrL_JaKiri "mars never contained life" Would you bet your life on that?

I'm trying to write a program in C++ that does square roots. does anyone know the algorithm for a square root using division, multiplication, addition, subtraction etc.

people who proved carbon dating ineffective. btw, how do you know humans weren't around back then? were you there to see no humans?

Does snow conduct electricity? how about ice? how about dry ice?

I made a very educated (based on facts) hypothesis that humans killed them BTW they dated a live penguin (carbon dating) 40k years old. I wouldn't rely on those dates.

try 21^(5/3) no calculator gets it right. Either a math error (overflow) or if you got a really fancy calculator (palm top) it will give you a really large number, which is wrong. Try it...... BTW the correct answer is: 3sqroot21^5 which is 159.8449148... Try putting the actual formula in , not step by step.

I am not sure, i have watched some videos that show evidence that the government is hiding stuff about aliens. If they control information flow, it won't leak

Due to polar ice caps, and some water vapour in the air, and the planet is covered with Iron OXIDE and there is hydrogen in the air. I would think there is water underground. The rocky surface doesn't seem to hold water that well The water may form caves, and as it vaporizes it may form a breathable atmosphere in those caves. Pretty interesting.

no bacteria, no viruses. It would be chaotic, image if nothing ever decayed, then no nutriens would be recycled, and you would eventually run out of food and die. There are tons of other things but i wont' go into all of them

There is a book of mathematical processes that theoretically prove time travel possible. It revolves around the idea that space is warped. Since space is warped theoretically you can catch one of the troughs and somehow appear at the inverse side of the trough, (hard concept to grasp), in this case, the difference in the timing would tear the spacecraft you are using apart, but think about it............answering a question before asking it........

thats a natural property in a coffee molecule, which is a compound. There is no real "substance" that causes that, its coffee. unless you want to chemically change coffee by altering the bonds in the molecule, it wouldn't be coffee anymore. So in other words, in my opinion, it can't be done.

php files can only be downloaded on an FTP protocol, if your FTP is password protected (should be by default) then you are ok. Your PHP interface should keep the SQL pretty secure. Of course skilled hackers can break through that code through a UNIX consol lets say...but unless you have Fat Tony's billions of dollars to hide, it shouldn't happen

Why does light refract when changing different refractive index mediums? A quantum theory question Just want to hear your side to it

they all echo. The only way they wouldn't echo is if you stick them in an air column designed perfectly for their sounds, and cause destructive interference. These are just myths, they do echo!!!

whoever wrote the article must be one of the only scientists still blindly fighting for its existance. It exists if they make it exist.

An addition: electricity is also used in electrolysis (to spark a chemical reaction (basically)) to make some medicines. The way i see it: increased current (ampers) creates burns, and increased voltage tampers with your nervous system (what doctors try to achieve in shocking a patient, to send a signal down a nervous system to start up the heart.) Electrical shop theropy is horrible, its a 1 second process and causes 40 seconds of seizures afterwards. It has been scientifically proven to do no good and I doubt its still used anywhere on earth.

I dare to stay out of theoretical physics

thats a theory
