Answer:
B
Explanation:
The second option correctly shows the process of cellular osmosis.
When the grapes would be immersed in water, the molecules of water move across the cell membrane from the region of low to high solute concentration. Due to this, the water would leave the cells and diffusion of water from the cells of the grapes. Thus, option B is the correct answer.
In conclusion, the procedure that uses a cluster of grapes left overnight in a high concentration of salt water would BEST demonstrate cellular osmosis (Option B).
Osmosis refers to the movement of a solution (often water) across a selectively permeable membrane.This movement (osmosis) is due to the difference in solute concentrations on both sides of the semipermeable membrane.In osmosis, water molecules move from a region of low concentration of solutes (e.g., salt) to a region of high concentration of solutes.
In conclusion, the procedure that uses a cluster of grapes left overnight in a high concentration of salt water would BEST demonstrate cellular osmosis (Option B).

How does a radio use radiant energy
Answer Explanation:
A radio uses an electromagnetic energy in the form of radiant energy. This is an invisible energy in the form of radio waves that can travel through space.
When it comes to radio, the radio waves are received by the radio tuner. It is then converted into sound waves that are audible to the human ears. Unlike the other electromagnetic radiation, the radio waves are harmless since they do not cause any harm to the human body. This is the reason why, it is more commonly used for telecommunications and toys controlled by remote.

WILL MARK BRAILIEST. Can someone help me wit des seven questions? (The issue is Air Pollution.)
1.) What is the issue? (Briefly describe the issue.)
2.) How does your issue affect 3 or more specific characteristics of the Chesapeake Bay?
3.) What specific actions are people taking to solve this issue or improve the situation? (Include 3 or more actions.)
4.) Describe how those actions will most likely affect the Chesapeake Bay. (Be as specific as possible.)
5.) In what ways does the Chesapeake Bay provide habitat?
6.) In what ways does the Chesapeake Bay provide opportunities for recreation?
7.) In what ways does the Chesapeake Bay provide opportunities for jobs and businesses ?
1. Air pollution is the presence of substances- such as carbon monoxide, nitrogen oxide, lead and sulfur dioxide- in the atmosphere that are harmful to the health of living beings, or damaging to the climate or other materials. Some causes of air pollution are burning of Fossil Fuels, aricultural Activities and waste in landfills
2. Air pollution from from power plants, vehicle exhaust, and other man-made causes have caused great affects to Chesapeake bay. Firstly, nitrogen from the air enters the Bay via the rain, which contribute to algal blooms. These algal blooms absorb oxygen from the water and create dead zones that cannot sustain marine animal or plant life.
Secondly, pollution from the power plants in the area- consisting mainly of the toxic chemical mercury- pose risk to anglers in the area. These contaminants can bind to sediment and enter bodies of small, bottom-dwelling organisms like worms, clams or crustaceans. Through a process known as bioaccumulation, fish that consume contaminated organisms can accumulate these toxins in their own tissue. Anglers are warned to limit their consumption of certain fish from the Bay due to potentially harmful levels of the chemical.
Lastly, exposure to air pollution will affect those living in, and visiting, the Bay. Air pollution can also cause headaches, dizziness, and nausea, as well as long-term health effects including heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also cause long-term damage to people's nerves, brain, kidneys, liver, and other organs
3. The Chesapeake Bay is arguably the most studied large body of water on earth. Forty years of intense scientific investigation by leading estuarine scientists have identified why the Chesapeake is degraded and how to fix it. No other water body in the world can boast this level of scientific understanding.
The first action being taken to protect the bay from air pollution is by planting more plant life in the area. Through a process called attenuation, forests can reduce the amount of pollutants in the air. The plants roots and leaves and forest soils absorb and trap airborne pollutants. They can capture more than 85 percent of the nitrogen that falls onto them from the air, keeping it out of the bay.
Secondly people are changing the way they travel around and near the Bay. To lower air pollution people consider learning how to drive the Bay-friendly way; walk bike, take public transport and carpool when possible. They also try to use electric or manual lawn mowers and yard tools instead of gas-powered machines.
Thirdly, the Environmental protection agency developed the Chesapeake Bay Total Maximum Daily Load in 2010 (TMDL). It set limits on the amount of nitrogen, phosphorus, and sediment that can enter the Bay and its tidal rivers to meet water quality goals. Ever since, the EPA has kept track on the progress of the Chesapeake Bays health.
4.
In planting more trees and plants near the Chesapeake Bay area, it will prevent some sediment and pollutants entering the water. The plants roots and leaves and forest soils absorb and trap airborne pollutants. They can capture more than 85 percent of the nitrogen that falls onto them from the air, keeping it out of the bay through attenuation.
Secondly by reducing the amount of pollutants entering the air via petrol powered machines and cars, the amount of pollutants entering the waters will decrease. Each year, more than 85 million pounds of nitrogen pollution—about one-third of the Bay's total yearly load—comes from air pollution, and with 18 million people living in the Chesapeake Bay watershed, you can imagine how much difference cutting down on transport generated pollution would make.
Finally setting the TMDL will aid in preventing the amount of pollutants in the water reaching a high concentration and hopefully reduce the amount of algal blooms and dead zones within the bay.
5. The bay provides habitat for many organisms. Amongst forests, rivers and streams, shallow waters, beaches and tidal flats, aquatic reefs, wetlands and waters- the bay supports life such as crabs, fish, birds, worms, molluscs, corals, aquatic plants, trees and shrubbery and amphibians.
6. There are many opportunities for recreation in Chesapeake Bay. For example hiking, bike riding, hunting, bird watching, boating, fossil hunting, fishing and golfing.
7. The Chesapeake Bay provides job opportunities for scientists in terms of studying the waters and the ecosystems existing within it, those wishing to attract tourists through the marketing of outdoor activities, those who work in the nearby native American or maritime museums and those selling seafood such as fishermen

PLS HELP FAST!!!! You have a natural-gas (methane, CH4) stove. When you ignite a natural-gas stove, the methane reacts with oxygen (O2) to produce carbon dioxide and water vapor. Write a balanced equation for this reaction, and be sure to show your work. (6 points)
Answer:
Methane (CH4) ( C H 4 ) burns in oxygen to produce carbon dioxide and water vapor. The balanced equation is: CH4+2O2→CO2+2H2O C H 4 + 2 O 2 → C O 2 + 2 H 2 O .
Explanation:
The balanced equation for the reaction of methane with oxygen is CH₄ + 2O₂→CO₂ + 2H₂O.
What is methane?Methane is a gas and a chemical compound with formula CH₄. It is a colorless and odorless gas and very flammable. It is made up of carbon and hydrogen. Methane comes under greenhouse gas.
As it is highly reactive, it reacts with the gases present in the environment. Here, methane is reacting with oxygen. When one molecule of methane reacts with two molecules of oxygen, it produces carbon dioxide and two molecules of water.
The reaction happens in the presence of heat and high temperature. The balanced reaction is written when the same number of moles are present on both sides of the reaction.
CH₄ + 2O₂ → CO₂ + 2H₂O.
Thus, the balanced equation for the reaction CH₄ + 2O₂→CO₂ + 2H₂O CH₄ + 2O₂ → CO₂ + 2H₂O.

Both natural processes and human activity are causing some of Earth's permanent bodies of ice to melt. If enough of this ice melts, it will add warm freshwater to the northern Atlantic Ocean, where deep water currents start. What effect is this likely to have
Answer:
EFFECTS - : Melting glaciers and icebergs release fresh water and reduce the salinity of the surrounding sea. The seawater also becomes less dense, changing patterns of ocean currents.
Explanation -
MELTING OF ICE AND ADDING WARM FRESH WATER TO NORTH ATLANTIC OCEAN -: As part of the thermohaline circulation (also called the Global Ocean Conveyor), seawater flows through the Atlantic, the normal pattern by which seawater passes to the oceans of the world. Due to variations in water density caused by differences in temperature and salinity, the water in the Global Ocean Conveyor circulates. Colder water is denser than colder water, while salter water is denser than fresh water or less salty water.
Water heated at the Equator flows north to cold high latitudes at the surface of the ocean, where it becomes colder. When it cools, the deep ocean becomes denser and sinks. To take its place, more warm surface water flows in, cools, sinks, and the pattern continues. But this trend may be modified by melting Arctic sea ice.
The influx of freshwater from the melting ice makes seawater less salty and thus less thick at high latitudes as the Planet begins to warm and Arctic sea ice melts. In reality, data shows that over the past few decades, the North Atlantic has already become fresher.
Answer:
Salinity changes in water
