How did the evolution of photosynthetic organisms help protect life from the sun's untraviolet radiation?

Because of photosynthesis, the partial pressure of O2 in the atmosphere increased. When ultraviolet radiation hits O2, it produces O3, which is an effective blocker of ultraviolet radiation.

Divergent evolution is also known as?
Adaptive radiation
Which organisms are not examples of an adaptive radiation?
Mammals and reptiles in the post-dinosaur age
A species or small group of species evolves into many new species during?
Adaptive Radiation pronounced(smeg-mah)
What pigments do plants use to carry out photosynthesis and what do these pigments do specifically for the process?
Chlorophyll a & b, caroten and xanthophyll are photosynthetic pigments used by plants. These pigments capture various wavelengths of solar radiation for energy transformation.
What affects organisms in undisturbed nature ecosystems?
An undisturbed ecosystem is an ecosystem that no one has been in for a very long time.
What is the type of evolution by which organisms evolve differences when they are isolated in different environments?
Allopatric speciation.Allopactric speciation. Geographic isolation. Adaptive radiation can also result from geographic isolation.
Divergent evolution is also known as?
Adaptive radiation
Is adaptive radiation the evolution of numerous species from a single ancestor?
yes
The evolution of ancestral species into an array of many spices that occupy diffret habitats?
A radiation event. Called adaptive radiation.
What is called when 1 species adapts into many?
I think the word your looking for is ' metamorphosis '. I think you are looking for evolution.
What role did ozone play in evolution of life on earth?
Ozone accumulated in the ozone layer reduced the amount of ulvraviolet radiation reaching the Earth's surface, thus allowing organisms with DNA to live on or near Earth's surface.
What are three of the natural sources that give off radiation?
- Radiation of cosmic origin- Radiation from radioactive elements (and decay products) of the Earth- Internal radiation of organisms
How is adaptive radiation different from divergent evolution?
I think it is Puncuated Equilibrium. I am not sure.No Punctuated Evolution is a period of stasis where no changes occur followed by sudden rapid change.It is Divergent
Animals are affected by radiation true or false why?
Yes they are. Simpler life forms have more resistance. Radiation catalyses mutations in the DNA sequences of organisms. This is why you can get cancer from radiation (e.g. skin cancer from ultra-violet radiation) because cancer is caused by mutations in multicellular organisms.
What types of radiation can cause cancer?
Ionizing radiation in the form of Gamma and X-Rays are hazardous to biologic organisms.
What is the radiant evolution in Darwin's theory?
Better known as "adaptive radiation", it is independent evolution from a population of a species that has become geographically isolated from its parent population.
What layer of gas shields organisms from the damaging effects of ultraviolet radiation?
The ozone layer shields us from ultraviolet radiation.
