Explanation:
The experiment is performed at a constant atmospheric pressure. The experiment proceeds by placing an empty flask in a boiling water bath. As the temperature increases, the air inside the flask expands. Afterwards, the gas is cooled in a water bath by maintaining the amount of the air in the flask constant.
A gauge records the pressure over atmospheric pressure (0kpa on the gauge is actually the atmospheric pressure and a reading of 276kpa is 276kpa over atmospheric pressure). That means that means that to find absolute pressure you just add atmospheric pressure (around 1atm (101kpa)) to 286kpa to get 387kpa. I hope this helps.
The cell membrane performs those functions. It is the outer layer of a cell and it creates a barrier, regulates material entry and exit, uses chemical signals, and creates structure.
Explanation:
The scale is pushing back up against her feet with the same amount of force but in negative direction.
This can be explain using Newton's third law of motion which states that "action and reaction are equal and opposite".
As the girl weight pulls down on the scale in a positive way with a force of 42N, the scale pulls back with an equal amount of force upward in another direction.
The net force here is zero this is why the scale is not damaged by her weight.

It was similar because they both arranged the elements in order of increasing atomic mass.
