Hi!! i think the answer is True!! Have a great day!!
Answer: D
Explanation:
lIf the change in the ecosystem occurs, then it would effect the weather, temperature, and the abiotic factors. So, we can see that the bacteria could survive in any sort of temperature. So, A can't be it. Also, B can't be it because the grass can grow in any sort of soil, even if the soil is contaminated. C cant be it because even if the change in the envoriment (temperature, contaimination) kills of one of the brown bear's food source, they can still have other things they can eat. But, if the weather gets too hot or the soil gets contaimnated and kills off the ecalyptus plants, the koala has nothing else to eat. So, best answer is D.
<u>Answer:</u>
When cells are in an <u>isotonic</u> solution, they are maintaining homeostasis.
<u>Explanation:</u>
"Homeostasis" is the process to maintain a stable and relatively constant internal environment. In addition to temperature it is maintained for many other factors too. "Isotonic solution" comprised of two solutions having the similar osmotic pressure across a semipermeable membrane.
Such solution maintain homeostasis of a cell via diffusion process. As in such solution the overall concentration on both sides of the membrane remains equal. The cell membrane command the movement regrading entrance and exit of anything in cell, the membrane control water and ion transport because of its phospholipid bilayer structure.
