Answer: <u>Option B; 100</u>
Explanation: If the cell is placed in a solution with 75 ppm calcium ions, then the cell will die, because water will enter the cells and they can burst. 75 ppm is quite a hypotonic solution for survival of bacterial cells. Same is the case will 125 ppm, here the cells will die because of dehydration. The increased solute concentration will make the bacterial cells to loose water and this principle is used in preservation.
100 ppm will provide the most stable environment because the water movement will occur at a same rate and the processes of the cell can proceed at required rate.
You'll most likely find out that his glucose levels have dropped.
Answer:
This organism is best classified as an autotroph.
Explanation:
Autotrophs can make their own food.
Increasing the number of stomata per unit surface area of a leaf when atmospheric carbon dioxide levels decline is most analogous to a human
B. putting more red blood cells into circulation when atmospheric oxygen levels decline.
<h3>What are stomata?</h3>
The stomata are apertures in the epidermis, each bounded by two guard cells. There are small openings on the lower surface of the leaves. These pores are called stomata. Loss of water from the stomata creates an upward pull, that is suction pull, which helps in the absorption of water from the roots. That is helpful for the transpiration process. They help in exchange for gases. Any of the tiny pores or openings in the epidermis of leaves and young stems are referred to as a stomate, sometimes known as a stoma, the plural of which is stoma or stomas. On the underside of the leaves, stomata tend to be more numerous. They enable the exchange of gases between the atmosphere outside and the leaf's branching network of interconnected air canals.

I’m pretty sure it’s weathering in erosion, though I took a test like this years ago and I’m not good at memory, so I don’t think I’m correct, but hopefully I am
