Please help. This model shows a strand of DNA. Identify how information for specifying the traits of an organism is carried in the DNA. A)
DNA codes for the sequence of nucleotides in RNA.

B)
The nitrogen bases in DNA code for the sequence of amino acids that make
up a protein

C)
The nitrogen bases in DNA code for the sequence of nucleic acids that
make up a protein.

D)
The sugar molecules found in the backbone of a DNA molecule code for
the RNA nucleotides.

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.
