I've a biology assessment in a couple of days. I was unwell a couple of months ago when we were going over a unit on microbiology so my knowledge on this particular topic is pretty bad. This topic going to be coming up in my assessment on Thursday.

Could anybody walk me through questions 3 onward?

Any help would be much appreciated.

I wasn't very good at the cell structures and the like, but I was better at the organisms part of bio. Is that what this is?

Kind of. It's more about cell sizes (ie. converting picometres to nanometres and then putting it in standard form etc.) - check out the link.

The curriculum in the UK is different to the US curriculum. I wouldn't be surprised if you haven't covered it.

No worries. I'll probably get Whiteflame or MagicAintReal to help me out on this one. They both have degrees on the topic so they'll probably know how to do it.

Thanks for trying though. :)

If I'm reading this right, I'm probably not, but there are 10000000000000 picometers or 1E+12 picometers in 1 meter. Then again, I'm probably not the best source. I don't know British science that well :P

Whilst in the UK the curriculum is different to the curriculum in the US, the units are the same and so is the conversion rate so if that's how it is in the US then that's how it is in the UK. Do you, by any chance know how many picometers there are in a nanometer?

Seems relatively straightforward to me.

Starting Question:
Eukaryotic organisms have organelles. Prokaryotic organisms don't. So you're looking for that difference. B is a plant cell, so it's clearly eukaryotic, as you can see a nucleus, vacuole and probably a mix of chloroplasts and mitochondria. A is almost certainly bacterial, as there's no clearly defined structures inside beyond a zone where the DNA probably resides and a membrane. I can't tell what C is, but since it contains a nucleus and what looks like several complex organelles, I'd say it's safe to call it eukaryotic. The last one isn't entirely clear, but based on the very defined circle at the bottom left, I'd assume it's eukaryotic. I'd guess an adipose cell in human tissue.

Question 1:
Flagella are for movement of the cell, that's simple enough. Organism C clearly has a flagella for that purpose. They contain motors that move them around and the direction those motors are moving can alter their direction. I'm not well versed in slime coats, but I know they mainly have protective functions against antibiotics and the like. I think you could just justify that by saying that it places a distinct barrier between the bacterium and the world around it.

Question 2:
Well, it's not in a nucleus. Usually ,it's free, but still manages to be localized (sort of) to an area of the cell. It's a circular genome as well. Don't know what else they want here.

Question 3:
a. A picometer is one trillionth of a meter. That's 1,000,000,000,000 to one meter.
b. 1*10^12

Question 4:
a. A nanometer is one billionth of a meter. That's .0000000001 (check the number of 0's, I don't have time to do so) meters. Since this is 20 nm, it's .000000002 meters.
b. 2*10^-8 meters
c. 4*10^-2 meters

Question 5:
(7*10^-2)/(3.5*10^-6), which looks to me to be 2*10^-8.

Extra challenge
There are probably a lot of effects, but the main one is that they can transfer DNA back and forth in the form of small circular pieces called plasmids. These can add genetic functions that don't exist in the genome of either organism.

Could you walk me through how you got this answer. These are the kind of questions that I generally struggle with the most.

Looking back at it, I got it wrong. I used the right numbers, but for some reason, I thought that 3.5*10^-6 was the magnification... which wouldn't be magnification, so I don't know how I got that. In any case, I'll redo it and walk you through the parts.

In order to determine magnification, you need to compare the size you have after magnification with the size you had before. In order to compare these two, you divide one by the other. That goes like this:

(Actual Size of the Bacterium)*(Magnification) = (Magnified Size of the Bacterium)

In order to determine magnification, you divide the magnified size by the actual size.

(7*10^-2)/(3.5*10^-6)

7 divided by 3.5 is 2, 10^-2/10^-6 is 10^4, so your magnification is 2*10^4.

Maybe think of them as fractions? 7 * 10^-2 is the same as 7/100, likewise with the other one. So just multiply numerators and denominators. (7*3.5)/(100*1000000), so 24.5 x 10^-8

You have the bacteria which is 3.5*10^-6 m and it looks as if it is 7*10^-2 m, so you are looking for a magnification factor X such that

3.5*10^-6 m * X= 7*10^-2 m

Solve that for X (divide by 3.5*10^-6 m)

you get

(7*10^-2 m) / (3.5*10^-6 m) = X

dividing by 10^-y = multiplying by 10^+y
m/m = 1

(7*10^4 / 3.5) = X
X = 2*10^4 = 20,000

You're right, ignore my post. I was multiplying the two fractions instead of dividing (which would be the same as flipping the 2nd one and multiplying: (7/100) * (1000000/3.5))
