On a molecular level, explain what happens when a kite lifts into the air?

NeTakaya

The difference in air pressure which is created by the molecules in air help to move kite up into the air.

Explanation:

When air moves faster, pressure of air becomes less. Air moves at a faster speed above the kite than below it and so its pressure is less on top of kite. The air pressure below kite is less. This difference in pressure results in uplifting of kite. Molecules of air with high pressure exerts more force on kite from bottom and thus pushing it up in air.

The greater is the difference between air pressure above kite and air pressure below kite, greater is the amount of force exerted on kite and hence, it reaches a greater height.

Each sentence describes an interaction between two of Earth’s spheres. Match each sentence with the spheres that are interacting

galina1969 [7]

The answers would be the following:

Geosphere and hydrosphere - water vapor condenses on a glass.

Hydrosphere and biosphere - Grady swims in the ocean.

Biosphere and atmosphere - Lena takes a deep breath

Atmosphere and geosphere - gusty winds weather sandstone in the desert.

If you'd like to know why:

Geosphere involves the solid part of the Earth, so that would mean it involves the rocks, land, and the like.

Hydrosphere involves water, your clue there would be hydro, which means water.

Atmosphere involves the air around us, which includes winds.

Biosphere refers to the biotic components. Bio means life, so we consider living things here.

Now all those spheres interact with each other, and it is through this interactions that our world is formed and how our Earth is able to sustain life.

Taking into consideration the features of each sphere, you can see that Grady is a living organism and the ocean is made up of water.

Hence, hydrosphere and biosphere are interacting.

Lena is a living organism, and she is breathing in air.

Hence, biosphere and atmosphere are interacting.

Water vapor is made up of water, and glass is a solid found on Earth. (Not really a good example of interaction between these two spheres)

Hence, hydrosphere and geosphere are interacting. 

Lastly, gusty winds is part of the atmosphere and sandstone is a type of rock.

Hence, Geosphere and atmosphere are interacting.

An animal cell with a 30% salt solution is placed in a beaker with a 20% salt

AleksAgata [21]

Answer:

the animal cell will burst

Explanation:

If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.

Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.

Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.

Examine this map to help you respond to the question: What is the most likely elevation of point B? 105 feet 125 feet 80 feet 75

Andru [333]

Most likely either 105 ft or 80 ft. If I had to choose between those two I would probably choose 80 ft however.
