Explain how temporal and spatial variation can change outcome of competition (which means you need to define the terms).

Behavior influences how organisms experience the environment and thus patterns of natural selection on behavioral traits. Which of the following examples is consistent with this statement? Some lizards in complex tropical forests prefer to hang out on tree trunks and branches, rather than the ground substrate, which has resulted in selection for shorter relative limb length and toe pads that can cling to bark. Ground-burrowing mammals experience greater exposure to dust and increased selection on their respiratory system to filter these particulates. Specialist parasitoids only target a handful of different host/prey types, resulting in a predictable resource and less selection on the ability to learn new resources All of the above Imagine that scientists have just discovered a weird new marine tunicate at extreme depths of the ocean. They have a novel kind of neurotransmitter – maritonin – that binds to the “maritonin” receptor, which is permeable to negatively charged iodine ions…

Which form of conditioning is used most for behavior modification? Why does this form work better? Why would Classical Conditioning help someone in their daily life functioning? Which form of conditioning would you most likely see in a classroom setting? Create your own examples of each form of conditioning. Be sure to include the following information in your answer. In addressing classical conditioning: Identify UCS, UCR, NS, CS, and CR. Discuss any stimulus generalization that you observed. Discuss any extinction and spontaneous that occurred. In addressing operant conditioning: Identify negative and positive reinforcements and punishments. Label the schedule of reinforcement or punishment.

The Tibetans and Han Chinese share several genetic traits and DNA. However the EPAS1 gene which increases the ability of red blood cells carry oxygen even in low environments, is only commonly found in the Tibetan population that live in higher elevations. Explain why this gene is commonly in Tibetan populations from the perspective of competitive advantage and natural selection. Write your answer in 3-5 sentences
