Snow slides down a mountain in an avalanche. Where would the snow have the
most potential energy?
Answer:
At the top of the mountain
Explanation:
The snow will have the most potential energy at the top of the mountain. Potential energy is the energy at rest of a body. It is a function of the mass, acceleration due to gravity and height of the body.
P.E = mgh
Since at the top of the mountain, we have the highest elevation. So, we expect that at the peak of the mountain the potential energy will be highest here.

explain what safety measures you might take to avoid damaging the microscope, microscope slide, or a living specimen on your microscope stage
Answer:
Some of the safety measures one can take to prevent damage to the microscope, microscope slide or living specimen include;
1. Always carry the microscope with two hands
2. Do not touch the microscope lens
3. Clean and store properly after using
Explanation:
1. Microscopes are delicate laboratory equipments and hence, should be handled with care. The proper way to handle or carry a microscope is to place one hand on the arm and the other below the base of the microscope. This will prevent the microscope from hitting something and getting damaged or something falling off.
2. The lens, either the objective or occular, is what makes visibility of any specimen possible. It shouldn't be mishandled by touching it or using inappropriate materials to clean it. A lens cleanser designed for that function should be used.
3. After use, the microscope should be cleaned thoroughly and stored in a dry place. The maintenance of the microscope will improve how long it will last.
The equipments used in the science laboratories require proper handling and safety measures to help the students and researchers to prevent any kind of illness and injury.
• The following are the safety tips to follow to avoid damaging the microscope, a living specimen on the microscope stage, or a microscope slide:
• One should use the microscope with two hands and should wear proper lab clothing.
• One should look at the specimen from the side, not via the eyepiece at the time of turning the low power objective as close as possible to the specimen at the time of the initiation of observations.
• One should avoid the application of coarse adjustment knob at the time of using the high power objective.
• One should prevent turning the fine adjustment knob more than a fourth turn to amend the focus at the time of using the high power objective.
Thus, one should follow precautionary measures while handling microscope and its components.

What is the function of the cell membrane in a cell?
Answer: The plasma membrane or cell membrane provides protection for a cell
Explanation: it also provides. Functions
The function of the cell membrane in a cell is that the plasma membrane or cell membrane provides protection for a cell or we can say that the function of cell membrane is to protect the cell.
What is cell membrane?The cell membrane has been defined as the structure found in the cell and the function of cell membrane is to provide protection to the cell. The cell contain several cell organelles and these are ribosomes, golgi appratus, nucleus, and the cell organelles have different functions.
When movement of molecules is takes place then it is called active transport. Active transport movement is always from lower concentration to a region of higher concentration gradients. So we can say that substance are moving their own concentration gradients.
Therefore, The function of the cell membrane in a cell is that the plasma membrane or cell membrane provides protection for a cell or we can say that the function of cell membrane is to protect the cell.
