Answer 1

Answer:

b

Explanation:

not sure but reletable

Answer 2

The device measure the level of medium in the fermenter as d)rotameter.

• Rotameter uses a closed tube to measure the rate of flow of fluid such as liquid and gases.
• It can also be used to measure the pressure at the end of pipelines.
• In the case of opaque fluid, the rate of flow measuring is somewhat difficult due to the invisibility of the fluid.
• The rotameter tube is breakable and should be used carefully.
• The thermometer measures the temperature and the spectrophotometer use the light intensity to measure the concentration of chemicals in a given sample by passing light through the solution.
• Galvanimeter measure current by showing deflection in needle.
