Select all indirect effects might increasing UVR have on animals?
Question 3 options:
selection for efficient DNA repair processess
selection for lighter pigmentation
a decreased survival of aquatic animals where dissolved material acts as a shield
wearing protective clothes
wearing sunscreen
an increased survival of aquatic animals where dissolved material acts as a shield
changes in behaviour
selection for darker pigmentation

UVR is short for Ultra-Violet Radiation. We're talking about indirect effects, so things that aren't directly caused by the UVR (NOT cancer, DNA mutations, sunburns).Some of the indirect effects are:
> selection for efficient DNA repair processes - UVR causes damage to DNA so organisms that are better at repairing damaged DNA are more likely to survive to reproductive age
> behavioural changes that allow the organism to avoid UVR
> an increased survival of aquatic animals where dissolved material acts as a shield - if the dissolved material in the water is shielding from UVR,
> selection for darker pigmentation - darker pigment, like dissolved material, shields the organism's cells from UVR
