Most bacteria have an optimal surface area-to-volume ratio (SA/V) that balances growth, available nutrients, and cellular components. A sphere-shaped bacterium and a rod-shaped bacterium have the same volume, but the surface area of the sphere-shaped bacterium is 4.6 µm2 and that of the rod-shaped bacterium is 0.8 µm2. Which statement compares the nutrient diffusion of the bacteria?

-It will be the same in the sphere-shaped and rod-shaped bacteria since both have similar SA/V ratios.
-It will be slower in the sphere-shaped bacterium since it has a higher SA/V ratio.
-It will be faster in the sphere-shaped bacterium since it has a higher SA/V ratio.
-It will be faster in the sphere-shaped bacterium since it has a lower SA/V ratio.

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
