                    How long would your DNA be if you stretch it out?

If you could take it out of a cell and stretch it into a line, our DNA would be more than six feet long. 

That's almost two meters.

Before the completion of the human genome project, many scientists were expecting to find 100,000 or more genes in our genome. 

This was based on the assumption that because we are one of the most complex creatures on Earth we should have lots of genes. 

However, it turned out we only have around 24,000 genes.

                    Do male marsupials have a pouch?

Acid and Bases have different different electrical conductivity based on density of free ions present in it.

It just depends on strength of acid/base.

Both can conduct electricity.
