PLEASE HELP I WILL MARK BRAILY LOOK AT THE PICTURE Scientists have made predictions about the universe today based on the big
bang theory. Observations that match these predictions support the big bang
theory. Which of the following observations have scientists made that
provides evidence of the big bang?
O A. Many galaxies that are similar to the Milky Way have been
observed.
B. Light from the moment of the big bang has been observed.
C. Galaxies are moving toward each other as predicted by the big
bang theory
D. The percentages of hydrogen and helium match the predicted
percentages.

Female luna moths (actias luna) attract males by emitting chemical signals that spread through the air. a male hundreds of meters away can detect these molecules and fly toward their source. the sensory organs responsible for this behavior are the comblike antennae visible in the photograph shown here. each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. what predictions does your hypothesis make? design an experiment to test one of these predictions.
