<span>A population of the frogs that do not receive the UV radiation would work as a good control group. In this case, since the impact of the radiation is the variable under study, a group that receives no radiation, and thereby should not exhibit a change, would be a control group that could be compared against the frogs that do receive the radiation.</span>
Answer: a. 6(3x2=6)

Explanation:
Coordination number= no of ligands
= No of ligands X denticity
Denticity is nothing but type of ligands like mono,do and tetradentate ligands.
Answer: operating machines they are easy to handle
Speed = distance/time
=> speed = 817/19 m/sec = 43 m/sec
hope it helps!
