Bacteria undergo mitosis and meiosis in order to reproduce and increase genetic recombination.
Salsk061 [2.6K]

Answer:

The correct answer is (b)-False

The first thing we can do to protect the ozone layer is reduce the use of natural gases. The gases produced from the natural gases had torn holes in the ozone layer. A way to prevent emissions of hazardous gases Is to switch to renewable energy. Renewable energy is not only easier to access and replace, solar panels and wind energy dont give off harsh and hazardous gases that mess with the ozone layer and the climate.

Explanation:

I don’t know how Many words that is. You can add to it if you feel the need to. I don’t know Hindi, maybe you can translate it on google?
