They cause less pollution. Renewable sources of energy, such as solar, wind, and hydroelectric, cause significantly less air and water pollution than non-renewable sources, such as coal and oil.
What is pollution?Pollution is the presence of toxic substances in the environment that can have a negative effect on humans, animals, and plants. It can either be the result of natural processes or due to man-made activities. Pollution can occur in the air, water, soil, and even in the food we consume. Common forms of pollution include air pollution, water pollution, plastic pollution, and noise pollution. Air pollution is the release of pollutants into the air which can cause harm to humans and the environment. Water pollution is the contamination of surface or ground water and can be caused by agricultural runoff, industrial pollution, and sewage. Plastic pollution is the accumulation of plastic particles in the environment that can damage ecosystems.

What conditions are needed do an accurate radiometric date to be obtained form a mineral sample?
Answer:
There are several conditions that are needed for an accurate radiometric date to be obtained from a mineral sample. These include:
The mineral must be a suitable type for radiometric dating. Some minerals are more suitable for radiometric dating than others due to their chemical composition and the type of radioactive isotope they contain.
The mineral must be in a closed system. This means that the mineral must not have exchanged any atoms with its surroundings since it formed. If atoms have entered or exited the mineral, it will not give an accurate radiometric date.
The mineral must be pure. If the mineral sample contains contaminants or impurities, it will not give an accurate radiometric date.
The mineral must be free of any damage or alteration. If the mineral has been damaged or altered in any way, it will not give an accurate radiometric date.
The mineral must be properly prepared and analyzed. The sample must be carefully prepared and analyzed using specialized equipment and techniques to ensure accuracy.
Overall, to obtain an accurate radiometric date from a mineral sample, it is important to ensure that the mineral is a suitable type, is in a closed system, is pure, is free of any damage or alteration, and is properly prepared and analyzed.

C. They destroy what we don’t need
the energy role responsible for capturing the energy from the sun and turning it into food is a
A. producer
B. Consumer
C. Decomposer
Answer:
A. Producer
Explanation:
The primary source of energy for almost every ecosystem on Earth is the sun. Primary producers use energy from the sun to produce their own food
Answer:
Hi, there the answer is A. producer
Explanation:
All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of a food chain always starts with plant life and ends with an animal. Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.
Why do organisms compete for food and water?
Answer:
Organisms compete for the resources they need to survive- air, water, food, and space. In areas where these are sufficient, organisms live in comfortable co-existence, and in areas where resources are abundant, the ecosystem boasts high species richness (diversity).

Where does wind come from? Why and how is wind stronger than other times? Or why and how is wind lighter ( not as strong) as other times.
Answer:
Wind is air in motion. It is produced by the uneven heating of the earth's surface by the sun. Since the earth's surface is made of various land and water formations, it absorbs the sun's radiation unevenly. Two factors are necessary to specify wind: speed and direction.
Strong winds are due to a strong pressure gradient force. A pressure gradient is how fast pressure changes over distance. So, when pressure changes rapidly over a small distance, the pressure gradient force is large. Strong winds almost always result from large pressure gradients.

is there an impact on the environment if blue whales went extinct? Who or what would it impact?
Without whales, krill would probably consume a large portion of the free-floating phytoplankton on the ocean's surface, accelerating climate change noticeably.
What makes the blue whale significant in terms of the environment?
Although blue whales have a huge food need, the ocean environment benefits from them rather than being burdened by them. Their iron-rich excrement is a crucial supply of nutrients for the marine food web, boosting production in the Southern Ocean and increasing fisheries yields.
What impact does blue whale extinction have on biodiversity?
The food source for many animals in the marine ecosystem is the carcasses of whales. The disappearance of whales would deprive other marine species of nutrients, which will have an impact on all species in the ocean.

Explanation:
Under normal cellular conditions, the FoF1 complex of the inner mitochondrial membrane functions to create new ATP. Under non-physiologic experimental conditions, isolated FoF1 complex can be driven in reverse as long as [ATP] is high. Which of the following would be true under such conditions?
A. The FoF1 complex would be operating as an ATPase rather than an ATP synthase.
B. The FoF1 complex would be driving net H+ movement from the matrix side to the IMS (intermembrane space) side
C. The FoF1 complex would create more ATP, per unit time, than it does under physiological conditions
D. As the experiment continues, we would expect to see higher & higher concentrations of ADP.
E. The FoF1 complex would effectively be operating as a proton pump.
Answer:
The answer is "Option A, B, and E".
Explanation:
In specific cell conditions, the F0F1 system of the inner mitochondrial membrane functions as an ATP synthase for generating new ATP ADP proteins and Pi. Even so, this has a specific biological role in non-physiological situations through functioning as an ATPase. Its ATPase acts in such circumstances and transmits large amounts of ATP to both the mitochondrial space throughout the transmembrane proton gradient.
The free radical of the transmembrane can be used by fermenting bacteria without an electron transport system. Its ATPase is being used to generate a proton gradient rather than to hydrolyze ATP. It may be used as a means of transporting flagella or nutrients into its cell.
The statements which are true about the FoF1 complex are:
The FoF1 complex would be operating as an ATPase rather than an ATP synthase.The FoF1 complex would be driving net H+ movement from the matrix side to the IMS (intermembrane space). The FoF1 complex would effectively be operating as a proton pump.So, the correct options are A, B, and E.
What do you mean by FoF1 complex?This complex is present in bacterial and mitochondrial H(+)-ATP synthases both consist of a membranous sector, Fo, which forms an H(+)-channel, and an extramembranous sector, F1, which is responsible for catalysis.
This FoF1 complex is the site of ATP synthesis along with the movement of protons (H+) from the matrix to the IMS. It is effectively operating as a proton pump because it mediates the transport of H+ ions out of the matrix.
Therefore, statements A, B, and E are correct with respect to the FoF1 complex.
