What is the best explanation for why a cell might shrivel?
A, There is less water in the cell than there is water in the environment surrounding the cell.
B, There is more water in the cell than there is water in the environment surrounding the cell.
C, The water solution in the environment surrounding the cell has a higher solute concentration than the cell.
D, The water solution in the environment surrounding the cell has a lower solute concentration than the cell.
The right answer is C, The water solution in the environment surrounding the cell has a higher solute concentration than the cell.
Plasmolysis (the phenomena of shriveling cell) is a cellular state of the plant cell where, following loss of water, the membrane is detached from the pectocellulose wall. This is the opposite state of turgescence.
Plasmolysis occurs when a stream of water comes out of the vacuole and the plant cell through osmosis. The resulting decrease in pressure causes shrivelling of the soft parts of the plant (stems, leaves, petals), which are no longer supported by the turgor pressure.
This flow of water is created either by the lack of water in the external environment, or by the presence in this medium of a liquid more concentrated than the cellular medium. In these situations, there is a displacement of water by osmosis from the cell medium to the external medium.
Thus, the cells of a plant subjected to a drought or a water too concentrated in salts will lose their water and will be in plasmolysis. The soft parts will then shrivel up and the plant will die of water stress if the situation does not allow it to quickly reabsorb water.

What is ridge push ?
(A) when edges become denser and gravity pulls them downward and away from one another.
(B) cooler and denser crust sinks into mantle.
(C) folding and crumpling and sliding upward creating mountains.
(D) currents just beneath earths crust flow very slowly causing movement In the plates above them.
This is for science.!!
Answer: (A) when edges become denser and gravity pulls them downward and away from one another.
During continental and oceanic plate tectonics. The plates collides with one another as a result of divergent tectonics. The edges at the point of contact gets displaced off from lighter plate and sinks at the bottom due to the effect of graviational pull. This is known as subduction. Due to force of collision these plates do not sunduct to the same location but are thrown to distinct places away from each other.
Which statement BEST describes why warm ocean currents are usually surface currents?
A)Warm water is less dense than cold water.
B)Ocean tides bring warm water to the surface.
C)Warm water contains more salt than cold water.
D)Ocean water loses heat to the air at the surface.
Warm ocean currents are usually surface currents because warm water is less dense than cold water, causing it to remain near the surface while cold water sinks to deeper levels.
The statement that BEST describes why warm ocean currents are usually surface currents is: A) Warm water is less dense than cold water. This is because the density of water depends on its temperature and salinity. Warm water, being less dense, remains at the surface while denser cold water sinks to deeper levels. This pattern is part of the global phenomenon known as thermohaline circulation, which combines temperature (thermo) and salinity (haline) to drive ocean currents. In addition to being influenced by wind, surface currents are driven by the density differences caused by temperature variations, with the warmer waters naturally tending to stay at or near the surface.
Moreover, processes such as evaporation and the formation of sea ice can affect salinity and thereby water density, leading the colder, denser water to sink and form deep ocean currents. The warm, less dense surface waters take their place, facilitating the global distribution of heat through the Great Ocean Conveyor Belt. This massive circulation system plays a vital role in Earth's climate by distributing heat and regulating temperatures across the globe.

A tight rope walker who does not want to change his position will want the forces acting on him to be Blank Space __________. Question 5 options: large small balanced unbalanced
The correct answer for fill in the blanks is Balanced.
Tight rope walker does not want to change his position to make sure that the force acting on him is balanced. A slight change in the position of the rope walker will make the rope move and this movement will result in the unbalance the force exerted on the walker. So, to make the force balance he will not change his position.

Which would have a better chance of becoming a fossil a fish that died and settles to the ocean floor or a mouse that dies on the ground in the forest
Some mixtures, such as the cup of coffee shown here, have the same appearance and properties throughout. What term best describes such mixtures?
A. homogenious
B. colloids
C. heterogenious
D. solutes
Answer: The answer would be A
Explanation: It would be A because it all looks the same, and it's all mixed evenly. A homogeneous mixture is something that IS mixed evenly, whereas a heterogeneous mixture is something that is NOT mixed evenly.
And I have absolutely no idea what colloids and solutes are:)

Which process is responsible for compressing successive strata in the earth?
(A) erosion
(B) faulting
(C) deposition
(D) folding
Answer:
d
Explanation:ez took it
Folding is responsible for compressing successive strata in the earth. Therefore, option (D) is correct.
What is folding ?The process of folding happens when tectonic processes put stress on a rock, but the rock does not break as a result of the stress. As the exposed faces of the folded rocks are worn away by erosion, this can result in a wide variety of landforms. Folds that resemble an arch are called anticlines, and folds that resemble the letter 'U' are called synclines.
This takes place deep within the earth, where the rocks are subjected to intense pressure and the temperature is much higher. Rocks that have been folded frequently occur in mountain ranges such as the Himalayas, the Alps, and the Scottish Highlands.
Therefore, option (D) is correct.

Why don't scuba divers lungs collapse as they descend?
Final answer:
Scuba divers' lungs do not collapse due to the use of compressed air from scuba equipment, which equals the surrounding water pressure. Divers equalize pressure in their body by breathing normally and using techniques to match the external water pressure. On ascent, divers must rise at a controlled speed to safely off-gas accumulated nitrogen and prevent decompression sickness.
Explanation:
Scuba divers' lungs do not collapse as they descend due to the design of the scuba equipment they use. The equipment provides compressed air from a tank, which compensates for the increasing water pressure at depth. This compressed air ensures that the pressure of the air breathed in is equal to the surrounding water pressure, preventing lung collapse.
When descending, divers must equalize the pressure in their body airspaces, such as lungs, ears, and sinuses, to match the external water pressure. They breathe normally to add air and equalize pressure in the lungs. In contrast, techniques like pinching the nose and gently blowing or using the muscles in the back of the throat are used to equalize pressure in the ears and sinuses.
On ascent, the ambient pressure decreases and gases dissolved in the blood become less soluble. To prevent decompression sickness (DCS), a diver must ascend at a safe speed, allowing the dissolved gases to be safely expelled from the body. If DCS occurs, hyperbaric oxygen therapy may be administered in a recompression chamber.
What can happen when you have taken much more than the normal amounts of vitamins?
Answer:
Excessive intake of vitamin hurts human body in several ways
Explanation:
Excessive intake of vitamin hurts human body in several ways. Some of the common harms caused are as follows -
a) Fat-soluble vitamins such as vitamins A, D, E and K if taken in excess cause building of toxic elements in the liver, brain and heart as they being insoluble in water are stored in body fat tissues.
b) Intake of Vitamin C - Excess of vitamin C causes problems such as cramps in stomach, nausea , diarrhea
c) Zinc & selenium intake causes harm to the nerves, hairs , gastrointestine etc.
