During a field trip, an instructor gently touched a moth resting on a tree trunk. The moth raised its forewings to reveal brightly colored eyespots on its hind wings. The instructor asked why the moth lifted its wings. One student answere that sensory receptors had fired and triggered a neuronal reflex culminating in the contraction of certain muscles that ralsed the wings. A second student responded that the behavior frightens predators and that this allows the moth to escape. Which statement best describes these explanations? A. The first explanation is biological, whereas the second is philosophical.
B. Both explanations refer to proximate causation.
C. Both explanations refer to ultimate causation
D. The first explanation refers to proximate causation, whereas the second refers to ultimate causation
E. The first explanation refers to ultimate causation, whereas the second refers to proximate causation.

Are characterized by dry conditions, limited vegetation and wide temperature range. a.) tropical rain forests b.) deserts c.) grasslands d.) none of the above

Cells tend to have a relatively small and uniform size. why aren’t cells larger?

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
