O Carbon dioxide and other pollutants are removed from the air.
Radioactive waste is produced.
Iron, lead, and zinc are produced.
Answer:
A. Carbon dioxide and other pollutants are released into the air.
Explanation:
Just took test
In the case of burning fossil fuels, carbon dioxide and many other air pollutants get released into the environment. The correct option is A.
What are fossil fuels?Fossil fuels are derived from the decomposition of plants and animals.
These fuels, which can be encountered in the Earth's crust and encompass carbon and hydrogen, can be burned for energy. Fossil fuels include coal, oil, and natural gas.
It aids in the release of carbon dioxide and other air pollutants in the air leading to air pollution.
Thus, the correct option is A.

Which row in the chart correctly describes what would be expected to occur in
the potato cells, with regard to both the starch and water molecules?
Answer: A (More Water Will Move Into The Cell And Starch Will Remain In The Cell).
Explanation: No Explaining, You Got 17 Minutes Left On The Test, HURRY UP! Just Trust Me.
Answer:
Water: more water will move into the cell than will leave the cell.
Starch: Starch will remain inside the potato cell.
Explanation:
Hey there!
In this case, according to the given information, and the chart, it is possible to infer that the water molcules outside the cell will have the capacity to move inside it, via difussion, as more concentration is outside, creating a potential able to induce the process. In addition, the amount of molecules of water that get into the cell is greater than those leaving it, because of the aforementioned.
Moreover, since no starch molecules are outside the cell, there will not be any potential inducing the difusion process, for that reason these will not move anywhere.
Thus, the correct row states:
Water: more water will move into the cell than will leave the cell.
Starch: Starch will remain inside the potato cell.

The diagram below shows a model of the circulatory system. Red represents blood that has high oxygen content and blue represents blood that has low oxygen content.
When one part of the heart contracts, blood moves from the heart to the lungs. Which statement best explains this motion of the blood?
A. The heart only contracts when it contains blood with high oxygen content.
B. The lungs cause the heart to contract when they need more blood.
C. The lungs move to inhale and exhale gases when the heart contracts.
D. The heart supplies the force that moves blood through the body.
Answer:
I believe it's C
Explanation:
Answer:
D. The heart supplies the force that moves blood through the body
Explanation:
When a chamber of the heart contracts, the pressure provides a force that makes the blood move. Valves make sure that the force pushes the blood in the correct direction. Therefore, the statement which best explains this motion of the blood is that the heart supplies the force which moves blood through the body.

What happens to the energy that is passed through to the primary consumer? List three possibilities
Please help
Answer: Primary consumers only obtain a fraction of the total solar energy—about 10%—captured by the producers they eat. The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat. You can probably see where this is going. Primary consumers are eaten by secondary consumers.
Explanation:
The energy that is passed through to the primary consumer is only 10% of their total energy as 90% of energy is lost in the metabolic process or excretions process.
The flow of energy in any ecosystem is linear from the sun to the consumers in an ecosystem. Energy is transferred from each trophic level to the next, however, only 10% of the energy of each level is transferred other 90% of energy is lost in the various process:
transferred to the next trophic level: If energy passed through the primary consumer then 10% of the total energy will transfer to the secondary consumerLost as heat or metabolic process: Most of the part of the energy is lost in performing various cellular functions and metabolic functions such as cellular respiration, digestion, reproduction, and others.Lost in excretion: some part of the energy is also lost in the excretion process.Thus, the correct answer and possibilities are given above.

Describe what lines up at the cell's equator during metaphase 1 of meiosis
During metaphase, spindle fibers attach to the centromere of each pair of sister chromatids. The sister chromatids line up at the equator, or center, of the cell. This is also known as the metaphase plate. The spindle fibers ensure that sister chromatids will separate and go to different daughter cells when the cell divides.
When tectonic plates slowly push against each other, forces build up and
eventually the plates move to release the tension. The movement of the plates is
caused by- *
Answer:
The movement is caused by the convection currents that roll over in the upper zone of the mantle. This movement in the mantle causes the plates to move slowly across the surface of the Earth.

A ______ frequency causes a _____wavelength and ______ energy. Lesson: 4.09 Question 10 options: higher, shorter, high low, shorter, greater low, greater, shorter higher, greater, shorter
Answer:
A higher frequency causes a shorter wavelength and higher energy.
A shorter frequency causes a greater wavelength and low energy.
Explanation:
Frequency is the number of waves that move at a period of time. It is measured by counting the number of crest point.
Wavelength is the distance between waves. A wave with higher frequency have crest that a very close and therefore the distance between them or wavelength is short compare to a wave with low frequency that the distance are farther apart and they have long wavelength. Therefore to generate high frequency of wave , more energy is required to do this .

During which stage of the cell cycle is the increase in nucleic acid polymers most apparent?
Answer:
The correct answer is - S or synthesis phase.
Explanation:
S phase or synthesis phase of the interphase is the phase of cell division which takes 5 to 6 hours to complete. In this phase the RNA content increases while DNA replication and synthesis takes place to provide enough genetic matter and polymer to complete the cell division.
Duplication or replication of the DNA increases the amount of nucleic acid for the successful division of the cell. S phase is the phase that prepares the parent cell for cell division.
