Hi, by the way like DNA what is the full form of RNA..

Ribonucleic acid is single stranded rather than double.

The page looks good!

Also, it consists of different set of nucleobases and has different purpose from DNA's.

Hi MIF

Maybe there should be a mention that not all cells divide by mitosis.

Good idea. I will say

What is Mitosis?

Mistosis is how some cells divide. The chromosomes in the nucleus are split into 2 identical sets. Then the nucleus splits into 2 nuclei. Theoretically these are perfect copies.

After that the cell will split into 2 complete cells. Process time varies but usually takes about 15 minutes or so and they can do it again in about 20 - 30 minutes or so. This is how protozoa and bacteria multiply. Also the infectious ones, so you see why an infection can spread very rapidly in the right conditions of temperature and food supply.

I am a bit late and did not get to check out sciencehq at it's release but it is fantastic. I was waiting for you to do science and this is great!

I think science is more easy than mathematics...

It depends. I find some parts of maths and science easy and some insanely arduous. Obviously math requires just as much problem-solving skills as the sciences, hence I find it impossible to compare the to subjects. To add to that, Science has 3 main classifications which are related only barely while math has multiple sub-classes which are definitely related. 1100th post by the way.

I am very happy you are making the sci-hq site.

Looks nice. The extra "s" is a typo though.

I am really impressed by the graphics of the

tree of live chart. Wow!!

A cell plate is necessary because plants have a cell wall and not a cell membrane.

Sure? I think it has both

Yes, plants do have a cellulose cell wall and a semi-permeable membrane.
