Answer:
B. It is studying the ecosystem.
Explanation:
Well, this is called echolocation. It is possible because the animals make noise, and it bounces off objects and plants. Their brain takes the sound waves that bounce off objects and register it into their brain at another way of seeing. They can see up to 200 miles away with this, and other animals can hear these noises from far away. I hope this answer cam to your desired help.
Rough ER - protein synthesis, transport of proteins throughout the cell
Smooth ER - lipid synthesis and cell detoxification
Transport of a substance from the lumen (cavity) of an organ into one side of a cell and out the other side of the cell into the extracellular fluid is called <u>transcellular transport</u>.
The two routes of transport of substances across the epithelium of the gut are by transcellular method and paracellular method.
Transcellular transport refers to the transport of solutes across a epithelial cell layer through the cells. The best example is the movement of glucose from the intestinal lumen to the extracellular fluid by the epithelial cells. The epithelial cells use the active transport to generate the transcellular transport. Active transport refers to the transport of substances from a region of its lower concentration to a region of its higher concentration against the concentration gradient using cellular energy.
