What are the effects of climate change on ecosystems? Ecosystem perturbations driven by climate change have direct human impacts, including reduced water supply and quality, the loss of iconic species and landscapes, distorted rhythms of nature, and the potential for extreme events to overwhelm the regulating services of ecosystems. How can humans change ecosystems? Humans […]

What factors influence conduction velocity?
What factors influence conduction velocity? Conduction velocity is influenced by myelin sheath thickness and internode distance (i.e. the distance along the axon between the nodes of Ranvier) (Hursh, 1939), and both parameters are linearly related to axon diameter. Why are we using two pairs of recording electrodes? Biphasic recording In this lab you will study […]

What is the relationship between kinetic and potential energy and speed?
What is the relationship between kinetic and potential energy and speed? The following equation is used to represent the kinetic energy (KE) of an object. This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic […]
