A researcher illuminated a filament of algae with light that passed through a prism, thus exposing different segments of algae to different wavelengths of light. He added aerobic bacteria and then noted in which areas the bacteria congregated. He found that the largest groups were found in the areas illuminated by the red and blue light. What can you conclude about the bacteria that congregated in areas other than red and blue light? Some bacteria have different forms of chlorophyll, which allows them to absorb different wavelengths of light.
Excess carbon dioxide in these areas attracted bacteria that complete anaerobic respiration.
Bacteria congregated in these areas because they contained carbon dioxide released by the algae.
Light of different wavelengths can be absorbed by aerobic bacteria but not by anaerobic bacteria.

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
