I was wondering if anyone could help me out with the flora and fauna which live in Koomba Park (Australia).

Any help even if it's just one organism, would be greatly appreciated.

Thanks in advance.

Recently when staining an onion cell with iodine, it didn't seem to react with any starch which i thought was odd (school lab wet mount). So basically what happened was it remained a brownish yellow color, with no noticeable effects. Was the iodine meant to turn blue reacting with starch, or make the cell more visible?

I'm making a calculator from Visual Basic 2010 but i couldn't quite get things going as i hoped. I'm trying to get the backspace button working so that it deletes the last digit (ones column).

I'm not sure why it isn't working but here's my code:

Dim str As String

str = lblDisplay.Text.Chars(lblDisplay.Text.Length - 1)

lblDisplay.Text = str

It gets rid off all the digits besides the last one (ones column) and this is really starting to fustrate me.

Any help would be appreciated, thanks.

Ok which do you like better, the 7 wonders of the ancient world or the 7 wonders of the modern world?

Also do you think the Angkor Wat or Great wall of China deserves the 'wonder' status?

Is it possible to make a file to run under the name of system, as in in task manager it has 'SYSTEM' under its user name. Any help would be appreciated, thanks.

Ok, i custom made an icon for a file but when i display it i have a black line bordering the left side and the bottom, any idea how to get rid of the black line? The black line wasn't apart of my original image btw.

Was wondering what temperature chlorine condenses at, and whether there is a reaction or way i could get the chlorine to condense into liquid with 13th century technology. Been searching and beginning to think its impossible.

When potassium manganate disproportionates in a low ph it produces potassium permanganate and manganese dioxide. But would the produces separate to form a layer or something and if so is there a simple way to separate them? And how much of each produce would you obtain if say we had 50g of the manganate.

My guess is that the maganese dioxide would be floating on top of the potassium permanganate. Would this be right?

To make hydrochloric acid you need sulfuric acid and salt (sodium chloride), they made this back in the time of renaissance but i have no clue how they did it. Could anyone please explain?

Or if you have another way just post it (without the use of electrolysis please).

Is it possible to create potassium permanganate from potassium manganate without the need of electrolysis?

First reasonable answers gets best answer.

In the medieval times, how did they build the cannon 'Pot De Fer'?

An image can be found here, this is an experimental one built a few years ago, i was just wondering how they managed to get the shape in the medieval times.

Did they use a mold for it or did they somehow bend a piece of metal into the shape?

Any suggestions would be appreciated.

I remember hearing about it on TV a few months ago and I'm trying to find the name of the picture. It shows an image of space but with two galaxies (or is it stars?) nearby each other but actually they are both images of the same star or galaxy. It was explained by the curvature of space-time i won't go into detail. Does anyone know the name of the galaxy/star or the picture?

Any one know what circuits cars use? Parallel or series (or both) and where do they use them?

By that i mean do they use it for the lights, or to start the engine, etc. Any information would help thx.
