Which of the following provides the strongest evidence of the role of heredity in determining intelligence? the intelligence scores of fraternal twins are more similar than those of ordinary siblings. the intelligence scores of adopted children show relatively weak correlations with scores of adoptive as well as biological parents. the intelligence scores of identical twins raised together are more similar than those of identical twins raised apart. the iq scores of identical twins raised separately are very similar.

What is the best-known carbohydrate?

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.

These are the components of the reservoirs of carbon that are exchanged in our environment.
