What did scientists use to come up with a theory about how the universe was created?

1 answer:

5 0

Answer: The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today.

Because current instruments don't allow astronomers to peer back at the universe's birth, much of what we understand about the Big Bang Theory comes from mathematical formulas and models. Astronomers can, however, see the "echo" of the expansion through a phenomenon known as the cosmic microwave background.

anygoal [31]

Answer:

d. A smaller body size

Explanation:

The smaller a body size is the larger the body surface area is. Larger body surface area would allow for increase in lost of more excess heat to the environment.

Therefore, hypothetically, one of the obvious adaptation that would be evolved by the rat population that was moved from their previous cold northern tundra climate to a desert environment is a smaller body size. This would enable them in cooling off and preventing over-heating.
