Which study led biologists to infer that the ancient archosaur was active during the night? ancestral state reconstruction sugge
sting that these animals had red fluorescent protein ancestral state reconstruction suggesting that these animals had green fluorescent protein ancestral state reconstruction suggesting that these animals had opsins that were shifted toward the red molecular clock analysis suggesting little evolutionary change from the archosaurs to their nocturnal descendants molecular clock analysis suggesting a great deal of evolutionary change from the archosaurs to their nocturnal descendants?
The correct option is this: ANCESTRAL STATE RECONSTRUCTION SUGGESTING THAT THESE ANIMALS HAD OPSINS THAT WERE SHIFTED TOWARD THE RED. Ancestral reconstruction is the extrapolation back in time from measured characteristics of individuals to their common ancestors. Opsins are a group of light sensitive proteins that are located in the photoreceptor cells of the retina of the eyes. Having opsin that were shifted toward the red colour will enable the animal to see very well in the night time, thus, the animal will be active during that period.
A climber at altitude has potential energy due to efforts to lift him higher in gravity's grip. His elevation gives him the potential to create kinetic energy if he had the misfortune to fall off
Answer: If the global warming trend continues and permafrost under the tundra melts, the biome that would you predict would replace it is:
Boreal Forest
Explanation: A boreal forest is a vegetation composed primarily of cone-bearing needle-leaved or scale-leaved evergreen trees, found in northern circumpolar forested regions characterized by long winters and moderate to high annual precipitation.
