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.

what are the similarities and differences between water and glucose?
Answer:
See the answer below
Explanation:
Both water and glucose contain hydrogen and oxygen. However, glucose has carbon in addition to the two elements. A molecule of glucose has 6 carbon, 12 hydrogen, and 6 oxygen atoms while a molecule of water has just 2 atoms of hydrogen and one atom of oxygen.
Both glucose and water are polar molecules.
Water is liquid at room temperature while glucose is a solid at room temperature.
In terms of structures, the overall structure of water is bent while that of glucose may be alpha or beta 6 carbon ring structure.

How are your coping mechanisms for feeling stressed
related to cellular homeostasis?
When a cell has too much of one thing, homeostasis gets rid of some of it and balances the cell out. Just like when you have too much stress, you find ways (coping mechanisms) to get rid of some of it.

Which of the following is NOT evidence of plate tectonics?
1. distribution of fossils
2. location of earthquakes
3. rain forest depletion
4. the shape of the continents
Rain forest depletion is not evidence of plate tectonics.
• Plate tectonics is responsible for the distribution of fossils on distinct continents, for the continental and ocean floor features comprising volcanoes, mountains, trenches, and faults, for the occurrence of earthquakes, and the shape of the continents.
• On different continents, the fossils are identical to the fossils found on the continents, which were once connected.
• The majority of the oceanic and continental floor features are the outcome of the earthquake and geological activity along the plate boundaries.
• The depletion of rainforest is not a result of plate tectonics. The major reason for rainforest depletion are agriculture and fuelwood collection.
• Apart from this, some of the human activities like logging, mining, development of large dams and industry is also major cause of rainforest depletion.
Thus, rainforest depletion is not evidence of plate tectonics.

How does being small help cells survive?
Cells are small in size because it is very important that they have a surface area to volume ratio that would allow adequate intake of food nutrients, as well as the excretion of waste materials.
A cell can be defined as the fundamental (basic), functional, structural and smallest unit of life found in all living organisms.
According to cell type, living organism are mainly divided into two (2) main groups and these are;
Unicellular organisms: these are living organisms that are single-celled i.e they have a single cell.Multicellular organisms: this category of living organisms have many (multiple) cells.It is very important that the surface area to the volume ratio of cell is small, so as to allow enough materials such as food, move through the cell membrane quickly for the survival of the cell.
Hence, cells are small in size because it is very important that they have a surface area to volume ratio that would allow adequate intake of food nutrients, as well as the excretion of waste materials.
In conclusion, the smaller a cell, the larger would be its surface area to volume ratio.
