Which study led biologists to infer that the ancient archosaur was active during the night? ancestral state reconstruction sugge
MrRissso [65]
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.

How does the amount of freshwater in glaciers and ice caps compare to the amount of freshwater in sources that can be easily acc
adelina 88 [10]

The fresh water is in a very big minority when compared to the total amount of water reserves on the planet.

The freshwater accounts for only 2%, while the rest of the 98% are saline water.

But the available freshwater for usage is even less, as from those 2% around 87% is frozen in the ice caps and the glaciers. Around 12% is groundwater, and not all of it is suitable for usage, and only 1% is the freshwater that is the most available from the rivers and the lakes.

This makes the freshwater a prime thing for preservation, as it is what enables the life on the planet, so much more measures have to be undertaken for it to be clean and in healthy condition.
