- In an exam question that regards this experiment, do we list the expected results or actual results? You will need to know the expected results and WHY you would get such results. - In an exam situation, what the hell do I do with the pH part since we didn't do it at all and got a...

Personally, I think Biotech is much more interesting than evolutionary biology (which is what Human story is all about).

You may also comment on the fact that you will see enlarged vacuoles within plant cells for leaves that are suspended in water. A decrease in vacuole size occurs in salt water.

I think this question require an applied understanding of osmosis. You will see enlarged (turgid) cells when a leaf is immersed in water, as water diffuse into cells. In contrast, you will see plasmolysed cells (the cell membrane shrinked away from the cell wall) in salt water because...

Justification should go under Discussion. A hypothesis is a hypothesis. It is a statement of what you think will happen. e.g. This bacterium will die after treatment with pencillin. then in the Discussion, you state WHY the bacterium cannot survive due to pencillin. e.g. penicillin inhibit...

I heard the module on Human Story has a lot of memorising to do. I'm sure you will do well even if you privately learn Genetics. Do you have assessments for the Human Story??

Maybe potato allow more water to enter its cells. It is easy to weight etc. It is cheap as well.

I think your teacher is looking for how you can improve your experiments. E.g. if you look at 1 leaf and write about the appearance and state that it was a fungal infection, would that be valid and reliable? How about state that you can look at 10 or even 100 leaves and describe the...

Excellent!

hmmm, BIOS1201 is a very enjoyable course. I'm a more molecular/cell person rather than macrobiology person (1101). I didn't do nearly as well in 1101 than 1201. The labs are similar, but a bit more work. I found the lectures on the animal stuff boring but that depends on who you are. I only...

hmm, a 3 uoc science course... there is a biomaths course (second year). Or most PHYS courses are 3 uoc.

Alternatively get into Medical Science, but ONLY if you know you want to major in the field of medical sciences.

It's still cool to get into Advanced science though :P But seriously NO real difference. Except you can choose to go to Singapore in second year for a short period of time.

I wish this is the case at uni. :(

Even though the concentrations vary, this is not that important when looking for bacterial sensitivey/resistant. As long as you whether they are resistant or sensitive, that's all it matters for a sensitive test. The concentration is set that way to reflect the maximum achievable...

Do you mean why some antibiotics are more effective than others? Antibiotics act differently. Some like penicillin or methicillin act on the cell wall. Erythromycin act on the ribosome and prevent gene expression. Some antibiotics act on the membrane. So their mechanisms of action make them...

May be this particular plant has genetic defects. Are all plants receiving the same amount of sunlight? Have you kept all variables controlled?

well.. a lot of bacteria can have shiny appearance. It usually prevent them from drying, rather than use it to cause you any disease. Most of the bacteria in your throat are commensal anyway. Unless you have identify this particular bacterium as Streptococcus pyrogenes, you shouldn't worry...

Although both scientists did their research in the mid 1800s to late 1800, to my knowledge, they worked independently of each other, and will, therefore, develped their theories of microbiology. You should research them separately. But just keep in mind that both of their contributions helped...

It would be easier if you tell us what exactly you want to know instead of outlining your whole assignment for us. We want to know what you understand so far and that you are not completely clueless as to who are Pasteur and Koch. Begin by looking at Koch and the Koch's postulates and how he...
