The primary reason surplus carbohydrates in plants are stored as starch is because: the space they occupy as carbohydrates is needed for other macromolecules. if they were left as individual monosaccharides, water would enter the cell by osmosis. all of these choices represent equally important reasons why surplus carbohydrates in plants are stored as starch. they would otherwise be utilized as energy sources even if such energy were not needed at that time. energy is needed in the nucleus, and only starch is capable of being transported into the nucleus.

Average annual precipitation and are the two major features that define the biomes on earth.

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
