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.

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.
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.
explain what can happen over million of years to the carbon compounds in organisms that can die and decompose?
Over millions of years, carbon compounds in dead and decomposed organisms can become fossil fuels due to anaerobic decomposition. When burned, these fuels release carbon dioxide into the atmosphere, contributing to climate change. Other geological processes can also release stored carbon.
Explanation:Over millions of years, the carbon compounds in organisms that die and decompose can undergo a series of transformations. Initially, decomposers like bacteria and fungi break down the decomposed organic material (dead plants and animals), releasing carbon in various forms into the environment. However, under particular conditions where oxygen is inadequate for complete decomposition, the partially decomposed organic matter can eventually turn into fossil fuels like coal, oil, and natural gas.
one significant source of carbon compounds is humus, which is a mixture of organic materials from dead plants and prokaryotes that have resisted decomposition. These fuels, when burned, release carbon dioxide into the atmosphere, contributing to global climate change. Other geological processes such as volcanic activities and tectonic movements can also lead to the release of stored carbon back into the atmosphere.
It's important to note that this process takes place over millions of years. Also, the rate at which we are using these fossil fuels far exceeds their rate of formation, making them a non-renewable resource.

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.
