How do active and passive transport help a cell respond to changes in the environment?
Active and passive transport help a cell in responding to the changes in the outside environment as both of these processes help in transporting substance into and out of the cell and maintaining the homeostasis in cell.
What is Cellular transport?
Cellular transport is the process of transportation of substances into and out of the cell. Cellular transport includes different processes such as active and passive transport. The active transport requires energy for transporting substances against the concentration gradient and the passive transport does not require energy as the substances move in the direction from high concentration to low concentration of solutes.
The transport of substances which are required by the cell and excretion is possible through active and passive transport. these processes helps in maintaining homeostasis in the cell.

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.

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
Give an example of an adaptive radiation. Provide evidence to support the claim that the radiation originated with one or a few species, that it was rapid and the descendant groups occupy a wide array of ecological niches. Suggest a hypothesis to explain why the radiation occurred.
Answer:
An example of an adaptive radiation with evidence to support the claim that the radiation originated with one or a few species is discussed below in details.
Explanation:
The method of evolution of various classes in a given geographical area originating from a spot and spreading to other regions or habitat is described as adaptive radiation. For example, modifications in nozzles of finches on Galapagos island.
Adaptive radiation indicates the adaptation of an organism that allows it to favorably spread, or radiate, into other circumstances. Adaptive radiation commences to speciation and is only used to explain living organisms.

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.
Cholesterol is synthesized by all animal cells and is an essential structural component of animal cell membranes. Cholesterol is the most common steroid and is mainly synthesized in the liver. Cholesterol also serves as a precursor for several important biological compounds including all, EXCEPT: A) insulin B) vitamin D C) bile salts D) testosterone
the answer is insulin. because the precursor for insulin is called pro insulin
Cholesterol does not serve as the precursor for insulin. So the correct option is A.
What is cholesterol?Cholesterol is a wax-like substance. Cholesterol is considered to be bad among the general public but it is not inherently “bad.” Our body needs for building cells and making vitamins and several other hormones. Cholesterol levels, in excess, can pose a problem.
Cholesterol can come from two sources. These are synthesized by the liver and from foods from animals. The liver produces all the required cholesterol but the remainder is obtained from foods. For example, meat, poultry, and dairy products of them contain dietary cholesterol.
These are the same foods that are also high in saturated fats and trans fats. These fats cause the liver to make more cholesterol than required or more than it normally does. This added production of cholesterol, for some people, means they go from a normal level of cholesterol level to unhealthy level of cholesterol.
Therefore the correct option is A.
