I defined all the answer choices for you and I hope it helps you. The answer I recommend would be B.
A: Osmosis is the movement of water or other solvent through a plasma membrane from a region of low solute concentration to a region of high solute concentration. Osmosis is passive transport, meaning it does not require energy to be applied.
B: Example of Simple Diffusion. In the cell, examples of molecules that can use simple diffusion to travel in and out of the cell membrane are water, oxygen, carbon dioxide, ethanol and urea. They pass directly through the cell membrane without energy along the concentration gradient
C: A process in which cell takes in materials from the outside by engulfing and fusing them with its plasma membrane. Supplement. Most of the extracellular materials that the cells absorb are large polar molecules (e.g. proteins and hormones) that cannot pass through the hydrophobic plasma membrane by simple diffusion.
D: During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.
A bioindicator is a living organism that gives us an idea of the health of an ecosystem. Some organisms are very sensitive to pollution in their environment, so if pollutants are present, the organism may change its morphologyphysiology or behaviour, or it could even die. Hope that helped!

Adult stem cells
very important for replacing lost or damaged specialized cells.
Life forms that depend on remineralize shells and skeletons will be harmed by ocean chemistry, as would species that are acid-sensitive and organisms higher in the food chain that eat these sensitive animals.
<h3>An organism is what, then?</h3>
An organism is a collection of molecules working together to form an more or less permanent together that demonstrates the characteristics of life. Definitions in dictionaries frequently use general terms like "any biological entity, such as a plant or animal reproduction."
<h3>What two kinds of organisms are there?</h3>
Prokaryotic and eukaryotic organisms are the two primary categories. These type the cells that form the organism are the basis for this differentiation. Prokaryotic cells have a very basic, rudimentary structure without a nucleus. Additionally, membrane-bound organelles are absent.
