You are looking at a slide using your microscope and see many things moving about. you notice a very rigid structure outlining the cell. you like to have as many facts as possible to back up any claims you make, specially in science. what else would you to be sure what type of cell you are seeing? question 4 options: lysosomes chloroplasts mitochondria cell membrane

The answer is; chloroplasts

Most cells have lysosomes, mitochondria and cell membrane. Hence these organelles cannot be used to differentiate cells. Chloroplasts, however, are only resent in photosynthetic cells such as plant cells and can be used as a distinguishing factor.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
