C. The cell must be a plant cell.
Only plant cells have cell walls. Bacteria cells and animal cells do not. Both animal cells and plant cells have membrane-bound organelles, but since the student saw a cell wall, it must be a plant cell.
Hope this helps! :)

Explanation:
Action potential can be split into 5 phases (0-4), where phase 4 leads from one action potential to the next. Phase 0 is the line up and is known as depolarization, it is here where the action potential is triggered and fast Na channels will open. Next, is phase 1 called early repolarization which is the little bit at the beginning of the plateau-here the Na channels will close. Then you have the plateau phase where Ca channels are open at the beginning and close at the end. Then is phase 3 called repolarization which is the big slope down and here is where the normal transmembrane ionic concentration gradients are restored. Finally, phase 4 which is the resting phase occurs. There are many resources online if you need more details, here is a pretty good one: http://www.pathophys.org/physiology-of-cardiac-conduction-and-contractility/
Stereomicroscopes is that they have a much lower magnification limit than other microscopes, such as the compound microscope, for instance. The stereomicroscope can magnify an image 100-150 times, while normal compound microscopes can magnify an image 1000-1500 times. This can be a disadvantage of stereomicroscopes, because not as much detail of the image is seen.
Answer: The question is incomplete because the options are not given. Here are the options gotten from another website.
A. adaptation
B. reproduction and development
C. response to the environment D. energy transformation
E. maintaining homeostasis
The correct option is maintain homeostasis which is C.
Explanation:
This is because salmon posseses adaptive physical characteristics that help it to suitably live both in freshwater and salt water. This is because homeostasis is the ability to resist any change in order to maintain body internal environment and this is a negative loop feedback. Organs of salmon work to control homeostasis but endocrine and nervous system engage more in maintain homeostasis.
