1. What was the purpose of creating a sodium bicarbonate solution? What was the purpose of adding soap to the solution?

1. Source of carbon  

2. Removal of cuticle

Explanation:

You may have been doing a photosynthesis lab in a biology course.

1. NaHCO₃

The purpose of creating a sodium bicarbonate solution was to provide the carbon that the plant needs for photosynthesis.

2. Soap solution

The soap solution acted as a detergent.  It removed some of the waxy, water-repelling cuticle from the leaf's surface and made it easier for the sodium carbonate solution to get inside.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
