Answer: For question one...B. Because cells are too small to see without a microscope. It would have been impossible because cells are hard to deal with without a microscope because they are so tiny. So, without it, he wouldn't have been able to get the answer out of his discovery.

For question two...D. The nucleus is the control center of the cell. The cell theory states that, for 1., All living things are made of cells and their product., 2. New cells are created by only old cells dividing into two, and 3. Cells are he basic units of life. Cells having a nucleus is not mentioned and will never be because, cells don't need a nucleus to keep moving or keep the cell in control.

I hope this helps you! I really do hope it does.

Write down five things that you personally could do in your day-to-day life to help with the problem of climate change. Write do
beks73 [17]
Before that, we need to know what causes climate change. One of the main reasons are the carbon dioxide released into the atmosphere, it traps heat but allow more heat to enter the earth, therefore climate increases over the years.

1. Set air conditioner to a higher temperature (eg. 25°C) or turn on fans instead.
Operating AC can use a lot of energy, and these energy is produced by burning if fossil fuels which releases carbon dioxide.

2. Take public transports instead of cars. The more private cars there are, the more pollutants it release, these pollutants includes carbon dioxide.

3. Turn off all the lights / electrical appliances when we leave a place. Again, electrical appliances require energy which is produced by burning of fossil fuels that gives out carbon dioxide.

4. Recycle and reuse paper that is only used on one side. Papers are extracted from trees and one main function of trees is to absorb carbon dioxide from the air. If many trees are cut, the amount of carbon dioxide in air would increase.

5. Do the laundry only if you have clothes full for the machine. If the washing machine is not full and you're starting it up, it really uses a lot of energy and water, which all again it triggers the release of carbon dioxide.
