How do organisms living in the marianas trench get the energy they need? sunlight reaches there and producers use photosynthesis in order to generate glucose necessary for cellular respiration. organisms use chemicals to mock photosynthesis and create stored chemical energy to be used later in cellular respiration. organisms are anaerobic and survive without oxygen. there is no life in these places on earth because life does not exist without photosynthesis.

What is a limitation of using a chemical formula, such as c6h1206, to represent a compound? the chemical formula does not show the types of elements that make up the compound. the chemical formula does not show how the atoms are connected to one another the chemical formula does not show the number of atoms of each element in a molecule. the chemical formula does not show the chemical symbols of the elements in the compound

Which label correctly identifies what x represents in the concept map?

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.
