Cassiopeia is a marine organism with a medusa body that has an unusual orientation: It floats upside-down. It also has a distinct coloration that is due to algae that live between the epidermis (outer) layer and gastrodermis (inner layer that lines the
digestive cavity) of the Cassiopeia. The algae provide food for the Cassiopeia, and the Cassiopeia's orientation provides sunlight to the algae for photosynthesis. Cassiopeia is a/an ________, and the Cassiopeia and the algae have a ________ relationship. A) mollusc; predatory B) arthropod; symbiotic C) cnidarian; symbiotic D) echinoderm; symbiotic
Lepidopterans (moths and butterflies) sometimes have specialized flying behaviors. Some moths have the ability to do sudden vertical drops when they detect bat sonar, to avoid being eaten. Other species use special flying techniques to attract a mate.When biologists talk about the "cause" of a behavior, they may be referring to two different things. The proximate cause is the sequence of physiological events that lead to the behavior in an individual. The ultimate cause is the adaptive benefit to the animal that allowed natural selection to sculpt the behavior over evolutionary time. Understanding both the proximate and ultimate basis of behavior is important, and different types of biologists may focus on each.A moth species is known for its unusual flying behavior, which includes
sudden vertical drops and horizontal zigzags. Not much is known about the cause of this behavior. What could you study to better understand the proximate basis of this behavior?
