Answer 1

Answer:

B. The number of trophic levels is limited, and typically is less than 10.

C. On average, about 10 percent of available energy is transferred from one trophic level to the next.

D. Among consumers in an ecosystem, first-level consumers have the most available energy

Explanation:

The number of trophic levels are limited. when one available energy is transferred from one trophic level to another trophic level, about 10 percent of energy is transferred whereas the rest of the energy about 90 percent is released in the form of heat energy. The first-level consumers have the most available energy due to higher biomass.

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)

Answers

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.

Bats are common in Texas especially in rocky regions bats with longer hang claws have demonstrated higher fitness because of their ability to cling to rock while resting this adaptive on is becoming more frequent in the population.What mechanism of evolution is this

Answers

Answer:

Natural selection

Explanation:

Natural selection is the mechanism of evolution in which organisms evolve in order to adapt the changes in the habitat for their survival. Living organisms are naturally variable and adjust themselves according to their surroundings.

In the given example, bats in Texas evolve themselves with longer hang claws to adapt the rocky nature of the surrounding. These longer hang claws provide them the ability to cling to the rock, which is an adaptive feature of bats that is influenced by the environment.

Hence, the correct option is "Natural selection".

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 ?

Answers

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

How does a radio use radiant energy

Answers

Electromagnetic waves carry 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.

what three animals are closley related to a tiger

Answers

Answer:

The tiger's closest living relatives were previously thought to be the Panthera species lion, leopard, and jaguar.

Explanation:

Results of genetic analysis indicate that about 2.88 million years ago, the tiger and the snow leopard lineages diverged from the other Panthera species, and that both may be more closely related to each other than to the lion, leopard and jaguar. The geographic origin of the Panthera is most likely northern Central Asia or the Holarctic region. The tiger–snow leopard lineage dispersed in Southeast Asia during the Miocene.

Panthera zdanskyi is considered to be a sister taxon of the modern tiger. It lived at the beginning of the Pleistocene about two million years ago, its fossil remains were excavated in Gansu province of northwestern China. It was smaller and more "primitive", but functionally and ecologically similar to the modern tiger. It is disputed as to whether it had the striping pattern. Northwestern China is thought to be the origin of the tiger lineage. Tigers grew in size, possibly in response to adaptive radiations of prey species like deer and bovids, which may have occurred in Southeast Asia during the Early Pleistocene.

Cholesterol also serves as a precursor for several important biological compounds including all, EXCEPT: A) insulin B) vitamin D C) bile salts D) testosterone

Answers

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.
