What does it mean if you can hear the tuning fork more clearly in one ear or another during the Weber test? How is the mechanism of hearing different if the handle of the tuning fork is held on the mastoid process instead of holding the tuning fork tines near the ear canal? What types of mechanisms does the body use for balance? How does vision affect balance? Imagine that you were standing on a moving platform when performing the balance test. How would this affect balance and why?

Populations of blue-winged warblers, a type of bird, migrate south in the winter and return to canadian breeding grounds in the spring. as global temperatures have increased due to climate change, spring has started arriving in the warbler's breeding grounds earlier in the year, before the warblers return. warblers now arrive at their breeding grounds too late to select ideal nesting sites and to feed on important early-spring food sources how are populations of blue-winged warblers most likely to be affected by the earlier arrival of spring? o a. populations will go extinct since the warblers will stop migrating to breeding grounds. b. populations will be unaffected since most species can quickly adapt to effects of climate change. c. populations will increase since warmer temperatures are generally beneficial to survival, d. populations will decline since individuals will be less likely to successfully reproduce, reset next
