A student was asked to create a model of a cell. Their model is incomplete. Which function would be impossible for the cell pictured?] A. Capturing energy from sunlight to create food for the cell would be impossible because it’s missing chloroplast. B. Everything would be impossible because it is missing the nucleus that controls all the cell’s activities. C. Storage of water and maintaining shape would be impossible because it’s missing the large central vacuole. D. Creating energy would be impossible because it lacks mitochondria

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.

thats a little if u want the answer just look it up on google thats what i do haha : )

im not exactly sure but i think its b!
