i need this for science class!!!!!!!!!!
If you do a bit of research, you will find that the answer is "THE MICROSCOPE". Look it up and see who invented it. Research is fun.
Before the invention of the microscope, you couldn't see a single cell due to the fact that they are too small to bee seen with the naked eye. With the invention of the microscope, scientists could now observe and study individual cells.

Invention implies creating something which didn't previously exist. Discovery implies finding something which no one had found before. You could have invented a telescope if you lived before it's inventors. You could use a telescope and discover an object which no one had noticed before.
Without the invention of new machines and technology , scientific discoveries that simply work and the Industrial Revolution could not have taken place. So new technology was necessary.
With the invention of the wheel, people could move heavier or bulkier loads further, in less time, and more easilly than before.
c) be turned in kerosene.

Before the telegraph people sent written letters and could take from days to weeks possibly a month to receive it.
At this point, we don't know. Inventions build on the discoveries of the past. Modern computers could not have been invented without the previous invention of the microchip. The microchip could not have been invented without the previous invention of the transistor. The transistor could not have been invented without the previous invention of the vacuum tube. The vacuum tube could not have been invented without the previous invention of electricity. What will be invented between now and 2030? We need to know the answer to that question before we could even speculate on what will happen in 2030.
