Places like the USA, even if you don't need a visa, you still need to apply for the waiver in advance. I think Australia has a tourist visa as well, not so sure about others.

! Moderator Note We're not getting back into that manuscript. Please stick to the topic.

That's fair. I had a number of friends who did a dual degree: a BSc (physics) and an engineering degree. It seemed to work pretty well for them. Perhaps you could pursue that? That way, if you find you dislike the engineering component or the physics component, you can drop one or the other degree. The engineering will be pretty general to start with though, so try not to get put off.

All sciences require a certain amount of memory work just to get the basics down. You build the logic and intuition from those things. That being said, I would agree that biology generally has a larger memorization requirement than say, chemistry or (maybe) physics, but that is because biology as a whole is quite broad and encompasses a lot of distinct sub-disciplines. There's just a lot of stuff going on in it. I can't comment on the differences between aerospace and physics. I will say though that it seems like you're really just attracted to the flashy side of things (in other words, the things that sound cool). It reminds me of a few friends in high school who wanted to study physiotherapy so they could becomes sports physio and work with professional teams. I personally don't think it's a very good way to go about selecting your major, as the chances are very much not in your favor at the end of the day. I'm not trying to discourage you, but it is important to be realistic about your expectations. I will say about aerospace, that I can't imagine there isn't a huge amount of memory work involved in it. Moreover, I know from some friends who are aerospace engineers and from friends who are other types of engineers, that it is considered the hardest engineering major there is. If you do go for it, be prepared for a lot of hard work.

Not much has changed with the general principles of TLC since the 1970's, I wouldn't think. As CharonY suggested, I'd look up a book on chromatography and read up on that. The concepts will be the same.

I've grown a lot of flowers and succulents. Flowers are tough here in the subtropics. Perennials end up being annuals the moment summer hits. I haven't had the time for it for a year or two. I used coffee grinds, which worked wonders. My succulents have been somewhat decimated by persistent mealy bugs, which came to me by way of a clipping from a friend. I have about half of the ones in these pictures: I haven tried crops. I don't own the house I live in, and the garden beds would need a bit of renovating to be usable. One day.

LOL. Oh dear. OP, please excuse my amazing brain fart.

No I got that, which is why I suggested you start there and come up with your own index.

Then what is it for? General curiosity? The first reaction is what makes chloroform. The ZnCl2 acts as a catalyst for the Cl- (from HCl) to substitute for the OH. This is then reacted with LiAlH4, which is a source of H- to give methane.

It will. You can either use the insert image button and post a link to the image if you have it uploaded somewhere, or you can upload them as files. If you click on More Reply Options, there should be an option to attach things at the bottom of the text window.

I can't really help you here, but is it possible to post an image of what you saw in the microscope?

! Moderator Note The purpose of this section of the forum is not to prove other people's hypotheses for them. That's your job, as is specified clearly in the rules. You have made assertions here that if they are not completely pulled from thin air, one could only logically arrive at them by a review of scientific evidence. Where is that evidence in you post? It is not our job to find it for you. At least one of these claims (namely, resistance to selection pressures)was criticised heavily in your past thread on this topic, and despite agreeing with it, you've made no attempt to change it in your text. What swansont was getting at is that this forum is for people to defend their already formed ideas, not request people to come up with the evidence for them. If you have specific questions about things you are not sure of, then you can post those questions in the main section. I am closing this thread for the above reasons, but also because we don't generally allow members to post multiple threads on the same topic.

Is this for homework?

Inappropriate in the sense that you dismissed his post, which contained some good and valid points, without actually responding to it. Inappropriate because that's hardly a way to hold intelligent discussion on a matter, and this is a discussion forum.

Could you not just generate your own index? Theodore Grey's, 'The Elements,' has some great information about elements, but if you're wanting to expand on that with consistent categories and information available, then I would think that the easiest way is to compile it yourself.

I don't see how iNow's comments to you were uncivil. Regardless, I don't think your response is appropriate. iNow brought up some excellent points in response to your post; the least you could do is actually respond to them.

That reaction is not going to make a nitro compound from an amide. I would suggest looking up peptide / amino acid reactions with peroxide. Would also be useful to know what amino acid / acids you're dealing with.

Sorry this is so late in posting. As I said before, the ratio of field work to sitting in front of a computer looking at data, is very skewed towards the latter. Finding research positions is hard regardless of the field. An rather small percentage of PhD graduates will go on into research-based careers, and even less will continue in academia. I can't imagine marine biology is any better. If you are picking a field based on likelihood of employment, I would go towards bioinformatics (though I'm not even sure that's correct these days). Still, if you are going that route and presumably planning on doing a PhD, then you will develop a host of other skills along the way that are transferrable to various positions across a number of sectors.

! Moderator Note Posts split from here. tkadm30, Could you please stop bringing back old threads from the dead and start your own? Thread necromancy is not against the rules, but it is when you drag them off topic.

Abortions in third trimester are extremely uncommon, and usually done due to extreme health risk to the mother. Your question is hardly a fair one.

I certainly don't agree. Growing up with one or two missing parents is hardly the same as growing up in an environment with two parents, homosexual or not. Incidentally, the research also does not agree. http://whatweknow.law.columbia.edu/topics/lgbt-equality/what-does-the-scholarly-research-say-about-the-wellbeing-of-children-with-gay-or-lesbian-parents/

In beer fermentation, you absolutely need cooling. Otherwise it generates too much heat, which can harm both the favour and yeast health. ETA: I had thought the above applied to wine as well. A quick Google search seems to agree with that.

This appears to be a homework question. DrP has already hinted at condensation polymerisation. What do you know about this type of polymerisation?

No, I believe you just get sleepy and pass out peacefully. It's why it's so dangerous.
