Dr. Hincapie recognized that the two larger pieces of DNA-
2100 base pairs and 1800 base pairs were from plasmids found
in bacteria that cause infections. The brightness of a piece of DNA
on a gel reveals two things: larger pieces of DNA are brighter
than smaller pieces and larger amounts of DNA appear brighter
than smaller amounts. Knowing this, which bands on this gel do
you think contain a gene for resistance to:

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

Acceleration is a direct result of a.) balanced forces b.) unbalanced forces c.) gravity d.) velocity

Individuals do not compete directly for resources, but are prey for the same predator
