When mendel crossed true–breeding pea plants that have inflated pods (pp) with those that have constricted pods (pp), it was observed that f1 offspring had a genotype of pp. what would their phenotype be? all offspring would have inflated pods, and none would have constricted pods. all offspring would have constricted pods, and none would have inflated pods. some offspring would have inflated pods, and some would have constricted pods.

The eruption of a nearby volcano causes a prairie ecosystem to receive a lot less sunlight. which of these is the most likely effect on the ecosystem? a-an increase in biodiversity. b-an increase in immigration to the area. c-a decrease in available water. d-a decrease in plant growth.

What is the difference between bacterial infections and viral infections?

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.
