The greater the surface area of a cell, the faster the cell can transport materials across its membrane because there is more area to absorb/excrete materials. We also want the surface area much higher than the volume of a cell. the more volume a cell has the slower the transport of diffusion will be. If the cell is smaller because it has a higher surface area than it does volume. Because of this larger SA:V ratio, smaller cells will transport materials faster.
In my opinion, the correct answer among the choice given above is option D. It is advantageous for grazing mammals to gather in groups because groups <span>offer greater protection from predation. It protects them because predators will think twice in nearing the group because it is outnumbered.</span>
Answer:
There are four categories for air masses: arctic, tropical, polar and equatorial. Arctic air masses form in the Arctic region and are very cold.
Answer: True
Explanation: Like all living things, prokaryotes need energy and carbon. They get energy from inorganic chemical compounds.
Chemoautotrophs are organism that utilizes inorganic molecules to supply energy for the organism, and use carbon dioxide as a carbon source. Chemoautotrophs are mostly prokaryotes that break down hydrogen sulfide and ammonia.
Most Eukaryotes cannot utilize these inorganic molecules as energy source.
It shows up in your stool. Specifically the undigested food includes material that cannot be absorbed by the vili found in the small intestine. Thereafter the material moves to the large intestine, goes through the bowel tract, turns into feces and exits the GI tract via the rectal cavity
