A scientist is explaining how background cosmic radiation gives evidence of the big bang theory. She says that radiation has been detected everywhere equally as heat in the universe and is increasing. This has been shown to be residual radiation from the big bang.

What error did the scientist make?

The radiation is not from the big bang, but caused it.
Radiation is not detected everywhere equally.
The amount of radiation should be lessening, not increasing.
This is not related to the big bang theory.

Ascientist conducted an investigation about the effects of diet on disease resistance in rats and made surprising observations. the mice with a genetic ear mutation seemed to show similar patterns of resistance compared to mice with normal ears. based on this information, what will most likely occur? a.she will perform a second investigation on the role of certain genes in disease resistance. b.she will revise her hypothesis to pertain to mutations rather than diet, and update her data accordingly. c.she will use this information to determine that her original question was nonscientific, so she will revise it. d.she will determine that her hypothesis was invalid because resistance must be genetic.
