E. coli cells grown on a mixture of glucose and lactose selectively use glucose because.

A) Cyclic AMP binding a protein (CAP) is not present when glucose is present
B) No lactose repressor is made under these conditions
C) Glucose lowers cAMP which reduces the amount of CAP-cAMP
D) Lactose interferes with glycolysis

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

In general, characteristics that an organism survive and reproduce become more common over time. what mechanism of evolution causes this?
