A student makes a monohybrid eross with Drosophila(fruit flies). She crosses two heterozygotes for the white eye. Wwx Ww. She expects to see a 3:1 phenotypic ratio of Red eyes (WW and Ww) to white
eyes (ww), her null hypothesis. She rears the next generation through to adult flies and counts the
following numbers: white eyes:210. Red eyes:680. (According to the chi-square test, did she get the predicted outcome?. State whether or not you reject the null hypothosis

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
