Some people worry that the increasing number of cell phones will cause cancer because of the energy of the radio waves they emit. Cell phones are a new technology that only recently became widely used. And because cancer takes years to develop, the amount of risk is not yet known.
Research this issue, and summarize what’s known so far. In your summary, include information about the energy of radio waves. Be sure to only use credible sources. Based on what you learned from your research, do you think people should limit their cell phone use? Why or why not?
p.s the is science
Answers
Answer:
no
Explanation:
because they bought it so it there’s they can do anything they want with it
Answer:
No, the increasing number of cell phones will not be one of the causes of cancer due to the low intensity of radio waves. Even though cell phones can not cause cancer, this doesn't mean cell phones are all that good for you. They can cause headaches, brain tumors, and poor eyesight problems. Even with using headphones or earbuds, you can cause damage to your hearing. In my opinion, I do think we should limit our cellphone time. Now, I am not saying we can't bring our cellphones when we are out of the house to make sure we can call if an emergency happens to pop up but simply saying we should limit our screen time at home. Just because phones may not cause cancer does not mean cell phones can't cause future health problems.

the answer is echolocation
Explanation:
Reason:
“Echolocation entails bats emitting high-pitched squeaks and using their highly sensitive ears to detect variations in the reflected soundwaves. This helps bats determine the location of insects, trees, or other objects in the darkness without the need for sharp vision.”

How does light energy in space compare to light energy on Earth?
Answers
Answer:
Light travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum? a completely airless space.
Hope it will help you
The difference is negligible due to three factors 1) Earth's gravity is too weak to noticeably bend light, 2) the speed of light is almost identical in our atmosphere and a vacuum, nd 3) even if Earth had the gravity of the Sun, we would need to be far away to see the bending of light.
What is Light?Similar to sound or water waves, light is a type of wave. Energy is transferred between places by waves. But no medium, including water or air, is necessary for light waves to travel. Even in an empty place, they can migrate (unlike sound waves).Since electricity and magnetism are both present in light waves, these waves are referred to as electromagnetic waves. Approximately 186,000 miles (300,000 kilometers) each second, these waves move exceedingly swiftly.Thus, a light beam might travel seven and a half times around the globe in a single second. There needs to be light for vision.When light strikes an item, it reflects or bounces back to our eyes. Visible light is a particular type of light that our eyes are sensitive to. All the hues that humans can see red, yellow, blue, etc are considered to be visible light.Actually, radio waves and light are the same. This form of light is detectable by a radio, which converts it into audible music. X-rays are a type of light as well.To learn more about light, refer to:

Describe the characteristics of a Wave: (Amplitude, Wavelength, Frequency plus Wave Speed).
Answers
Waves all have an amplitude which is the height of the wave from sea level, wavelengths which is the distance between crest to crest or trough to trough. Waves also have a frequency which is the number of waves that pass in a given amount of time. Another characteristic of a wave is wave speed. A wave speed is a pace that a wave travels in a given amount of time. (I HOPE THAT HELPED :))
Answer:
No matter whether you are talking about vibrations or waves, all of them can be characterized by the following four characteristics: amplitude, wavelength, frequency, and speed. The amplitude of a wave can be described as the maximum distance the molecules are displaced from their starting place .

Explain how low atmospheric oxygen levels affected alligator growth in terms of cellular respiration.
Answers
Answer:
Hyperbolic alligators exhibited the lowest breathing rate and highest oxygen consumption per breath. We suggest that, despite compensatory cardiopulmonary remodeling, growth of hypnotic alligators is constrained by low atmospheric oxygen supply, which may limit their food utilization capacity.
Explanation:
Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, low atmospheric oxygen levels affected alligator growth in terms of cellular respiration.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
The oxygen dissolved in sea water is used by marine animals in breathing. Hyperbolic alligators exhibited the lowest breathing rate and highest oxygen consumption per breath. Low atmospheric oxygen levels affected alligator growth in terms of cellular respiration.
Therefore, low atmospheric oxygen levels affected alligator growth in terms of cellular respiration.

How can acid change the shape of earth's surface?

So Acid changes the shape of Earth by damaging the natural resources of Earth through Acid Rain. The Harmful Gases like Sulphate, Nitric oxide Mix with water vapour of earth atmosphere and Comes to earth by rain consisting of Acid and Damage the Shape of surface of Earth
Answer:
See below.
Explanation:
First let's review with the basics of this topic.
Factors
Chemicals only turn into acids when moisture and sunlight combine.Because of this process, when the acids come back to the Earth's surface, it comes back as acid rain. Rocks like limestone, marble, and others kinds of stone can be affected and weathered by acid rain rapidly. This process effects the surface of the Earth as these rocks make up the shape of the Earth's surface.
