Describe fully what will occur if a plant cell is placed in a solution that has a higher water potential than the cell. Use the following terms in your answer.cell wall, freely permeable, partially permeable, cell surface membrane, vacuole, tonoplast, cytoplasm, solute potential, pressure potential, water potential, turgid, osmosis, protoplast, equilibrium
Answer:
tortinos
Explanation:
hot pizza rolls
When the plant is placed in the higher water potential, the water will diffuse from the higher water potential to the lower water potential and make the plant cell turgid. As a result, the plant cell will swell.
What is the plant cell in a hypotonic solution?When a plant is placed in a hypotonic solution, that means the plant cell has less water potential than the outer side, and as a result, the water will flow from a higher water potential to a lower one. The plant cell membrane is partially permeable, and water will diffuse from the outer to the inner, causing the cell to exert more pressure on the cell wall and swell.
The vacuole will swell too in such a case, and the movement of water is called osmosis. The hypotonic solution has less solute potential, and the flow of water will continue until equilibrium is maintained.
Hence, this is the osmosis process, where the water will flow freely from the outside to the inside of the cell cytoplasm and make the cell turgid.

Answer:
hollow bird bones or option c
Explanation:
because it helps them fly better
Hollow bird bones is not an example of an internal structure adaptation.
What is Internal structure adaptation?Any heritable characteristic that enables a plant or animal to survive and procreate in its environment is referred to as an adaptation. Individuals of a species can differ in a wide range of ways; some may be larger, hairier, better able to fend off illnesses, or even have smaller ears.
Their genes, which are inherited from their parents and later passed on to their own offspring, are mostly responsible for determining these traits.
The proportion of people who possess that favorable feature or adaptation will rise over generations until it becomes a characteristic shared by the entire species.
Therefore, Hollow bird bones is not an example of an internal structure adaptation.

Answer:
They interact by the upper mantle transferring energy by conduction to the core assisting in the softening of the rock layer which leads to radiation.
Explanation:
Convection currents coming from the core and mantel are believed to the main cause of the interaction. As these currents travel up and down the curst and mantle boundary and this creates the plates to move freely forming a conveyor belt. The core of the earth creates this convective current to rise up due to the heat and pressure. The hot molten rocks in the mantle eventually cool and the cycle of rising and sinking takes place.answers :

n the northern United States where snow and ice create dangerous road conditions in the winter, the Department of Public Transportation often salt roads, which encourages melting. How could salting the roads have and impact on the plant life that live on the edge of the road?
Plant cells will lose water due to osmosis.
Plant cells will gain water due to osmosis.
Plant cells will use the salt to grow taller.
There would be no impact.
Answer:
Plant cells will lose water due to osmosis
Explanation:
Osmosis uses a concentration gradient. Water travels from areas of high concentration to low concentration. The salted road has low water concentration while the plants near the edge have a higher water concentration. The water will leave the plants and go to the salted road. Using common sense, if you sprinkle salt on a snail, it dehydrates and dies. Same thing happens here. The salt sucks the water out.

1. The human population is increasing by about 1.19 percent each year. Assume that the
population is 6.8 billion (6,800,000,000).
How large will the population be in one year?
The population that should be large in one year is 8,092,000,000 when the population should be increased by 1.19 percent.
Calculation of the population:Since the population is 6.8 billion or 6,800,000,000
And, the increase rate is 1.19% each year
So the population in one year should be
= 1.19% of 6.8 billion
= 8,092,000,000
hence, The population that should be large in one year is 8,092,000,000 when the population should be increased by 1.19 percent.

Answer:
Answer:
5. when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent
6.They are moving toward each other
7. The Nazca Plate is bounded on the west by the Pacific Plate and to the south by the Antarctic Plate through the East Pacific Rise
8.Convection currents in the mantle drive plate tectonics. Convection is the reason for ocean currents. Ocean currents result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement.
Both the mantle and ocean experience the heat transfer due to bulk movement of molecules within fluids such as gases and liquids, including molten rock; this is called, again, convection.
What is the direct cause of most earthquakes?
O Gravitational pull on bedrock by the moon
O deposition of sediment in lakes and oceans
O movement of bedrock along a fault line
O heat exchange betwęen the crust and the atmosphere
Answer:
Pretty sure it's C or B? Most likely C.
The direct cause of most earthquakes is the movement of bedrock along a fault line. Earthquakes occur when energy stored in the Earth's crust is released suddenly, causing the ground to shake. Hence option D is correct.
What is an earthquake?An earthquake is a sudden and rapid shaking of the Earth's crust caused by the breaking and shifting of rock beneath the Earth's surface. The Earth's crust is made up of tectonic plates that constantly move and interact with each other.
When these plates move against each other, they create pressure that builds up over time until the rock breaks, causing an earthquake.
This energy is released when two blocks of rock, called tectonic plates, move relative to each other along a fault.
The blocks may become stuck, and as the pressure builds up, they may suddenly slip, releasing energy in the form of seismic waves that cause the ground to shake.
The intensity and magnitude of an earthquake depend on the amount of energy released and the distance from the epicenter.
While other factors such as volcanic activity, landslides, or human activities can also cause earthquakes, movement along a fault line remains the primary cause.
Hence option D is correct.

The shadow zone exists due to the of seismic waves.
O A. reflection
O B. refraction
O C. absorption
OD. deletion
Answer:
B. refraction
Explanation: hope this helps!
The shadow zone exists due to the effect of seismic waves is the refraction. Thus, the correct option will be B.
What is Refraction?Refraction can be defined as the redirection of a wave as it passes from one medium to another medium. The redirection of the waves in a medium can be caused by the wave's change in speed or by a change in the medium of wave.
Seismic waves are the waves which follow the same law of refraction at the compositional boundaries. If the seismic wave velocity in the rock below a boundary is increasing then, the waves will be refracted in the upward direction and this speed up relative to their original path of movement.
Therefore, the correct option will be B.
