Explain how technology helps to compare and study genes and proteins.
maksim [4K]

Answer: Modern technology can analyze, compare, and save more information than our brains can. Genes and proteins are small, but 3D modeling on computers can help build it to a scale that we can see. Information can be saved  and stored for later use, and it's easier to access when it's all on one operating system.

Within each eon, identify major events and the types of life that dominated the Earth during the time.​
blagie [28]

There has been two eons in the Earth's geologic history so far, the Precambrian eon, and the Phanerozoic eon. The eons are the basic and by far longest units on the geological time scale, spreading over hundreds of millions of years.

The Precambrian eon is the eon that starts with the formation of the Earth, up until the development of multi-cellular organisms. A very important event in this eon can be considered the formation of the Earth's oceans, which later enabled the conditions for the development of life. The organisms that dominated this eon are the one cellular organisms.

The Phanerozoic is the eon in which the multi-cellular organisms started to develop and evolve. This eon started with the end of the Precambrian eon, 543 million years ago up until the present. A very important event in this eon is the change of the composition of the atmosphere, which enabled the terrestrial life, as well as the better living conditions for the marine life. It is very hard to choose a dominant form of life in this eon, but worthy of mentioning are the plants, the sinapsids, dinosaurs, mammals, fish.

How do monarchs warm up and stay warm?
sp2606 [1]

Answer: Search Results

Featured snippet from the web

Monarchs can warm up by basking in the sun. Basking helps a monarch raise its muscle temperatures to flight threshold. When monarchs bask they open their wings and tilt them toward the sun. Like solar panels, monarchs capture the sun's energy by exposing the surface area of their wings directly to the sun.
