b.
increases photosynthesis in plants
c.
causes damage to living tissue
d.
filters out harmful ultraviolet radiation

Answer is: d. filters out harmful ultraviolet radiation.

The Ozone layer is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation.

Molecular formula of ozone is O₃.

Ozone is allotrope of oxygen and he is less stable. Because his unstability in high concentration, ozone decaying to diatomic oxygen.

it's c (engineer's do their work with mechanical stuff not on any living being)

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
