Living systems store, retrieve, transmit, and
respond to information essential to life processes.
Essential knowledge 3.B.2: A variety of intercellular and intracellular signal transmissions mediate gene expression.
Essential knowledge 3.E.1: Individuals can act on information and
communicate it to others.

a. Organisms exchange information with each other in response to
internal changes and external cues, which can change behavior.
Students should be able to demonstrate understanding of the above
concept by using an illustrative example such as:
• Fight or flight response
• Predator warnings
• Protection of young
• Plant-plant interactions due to herbivory
• Avoidance responses
b. Communication occurs through various mechanisms.
Evidence of student learning is a demonstrated understanding of each
of the following:
1. Living systems have a variety of signal behaviors or cues that
produce changes in the behavior of other organisms and can result
in differential reproductive success.
To foster student understanding of this concept, instructors can
choose an illustrative example such as:
• Territorial marking in mammals
• Coloration in flowers
Organisms have certain adaptations that increase their rate of survival by decieving predators through means of cryptic coloration/camouflage. They create a signicant change in behavior by displaying morphological and physiological defensive adaptations, including aposematic coloraion with bright intense colors and two types of mimicry, batesian and mullerian
herbivoryvis a +/- interaction where an organism eats a plant or algea. coevolution where grasses have evolve to grow from the bottom unlike other plants, another example would be cactus that evolve spikes in order to avoid being eaten.
