A group of students were asked to study and record the movement of amoeba to try and determine how they move. The group knew that they must plan this descriptive investigation carefully, including the selection of the appropriate technology needed to observed these single-celled organisms. Which type of microscope would be most appropriate for this investigation? A) Compound Light Microscope B) Scanning Electron Microscope (SEM) Stereo Microscope (Dissecting Scope) D Transmission Electron Microscope (TEM)​

B. Scanning Electron Microscope

Explanation:

We know that C and D just take pictures but are not able to be compared to one another so in conclusion These answer choices are out of the question and I believe for it to be B.

A. Compound Light Microscope

Explanation:

USA TestPrep

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
