Answer:
Radio frequency is short for RF, which is a kind of high frequency alternating current electromagnetic wave with frequency range from 3k hz-3k GHz
Because the frequency is high, so the molecular movement speed is fast, and the physical explanation of the heat of the object 100 is its internal molecular movement speed, the use of radio frequency energy to make the molecular high speed movement of course will achieve the purpose of heating
Answer:
Radiofrequency (RF) radiation, which includes radio waves and microwaves, is at the low-energy end of the electromagnetic spectrum. It is a type of non-ionizing radiation. ... If RF radiation is absorbed in large enough amounts by materials containing water, such as food, fluids, and body tissues, it can produce heat.

Juanita is planning a scientific experiment to observe and record her community’s daily activities that release carbon dioxide into the atmosphere. She will use the data collected to construct a model. This will help make informed decisions on how best to reduce emissions and protect the environment. Which of the following activities would increase the amount of carbon dioxide in the atmosphere? Choose the three that apply.
A. plants conducting photosynthesis
B. eating a sandwich
C. a deer dies along the road
D. cutting down trees in a forest
E. driving a car to the store
Answer:
C, D, E
Explanation:
A: When plants photosynthesize, they actually use carbon dioxide in the process. Therefore, that would decrease the amount of carbon dioxide, so this choice is wrong.
B. Eating a sandwich has no effect on carbon dioxide levels.
C. If an animal dies, they are broken down by decomposers. During this process, any carbon in the animal's body is released into the atmosphere as carbon dioxide. This would increase the amount of carbon dioxide.
D. As stated before, plants photosynthesize. If we cut down trees, there will be fewer plants to take in carbon dioxide during photosynthesis. This will increase carbon dioxide levels.
E. When a car converts fuel into energy to move the car, carbon dioxide is released. Driving a car will increase carbon dioxide in the atmosphere.
C, D and E are correct.

Do shrimp follow the Carnegie stages of development?
Shrimp Eggs: The shrimp start as small almost invisible eggs and are food to zooplankton until they spawn due to becoming stimulated by temperature change and become larvae.
Nauplius Larva and Protozoea Larva: Larvae developed from fertilized eggs.
Mysis Larva: These are carried toward shore and continue to feed on zooplankton and phytoplankton.
Postlarva: These tend to be moved toward brackish waters and begin to look, forage, and graze like shrimp. They develop swimming and walking legs.
Juveniles: They can continue to interact with many species as predator and prey.
Subadult: Temperature changes stimulate growth and regulate its migration to sea.
Adult: Continues to grow on the sea bottom. Many are fed on by animals such as pinfish, silver sea trout, sharks, and redfish and snared by commercial trawlers.

Gene expression in prokaryotes is regulated at which stage?
A. Translation
B. Transcription
C. Post-transcriptional modification
Answer:
B. transcription
Explanation:
Prokaryotic transcription and translation occur simultaneously in the cytoplasm, and regulation occurs at the transcriptional level. Eukaryotic gene expression is regulated during transcription and RNA processing, which take place in the nucleus, and during protein translation, which takes place in the cytoplasm.

During what period were fossil fuels formed?
Fossil fuels were formed between 360 and 300 million years ago during the ________
period.
Fossil fuels were formed between 360 and 300 million years ago during the carboniferous period.
What is carboniferous period?During the late Paleozoic Era, the Carboniferous Era extends from 359.2 to 299 million years ago*. The concept "Carboniferous" emerges from England, where there are abundant coal deposits. Coal deposits can be found in northern Europe, Asia, and midwestern and eastern North America.
The Amphibian Age is another name for the Carboniferous Period. It is the fifth of the six geologic periods that comprise the Paleozoic Era.
The Devonian Period comes before the Carboniferous Period and the Permian Period comes after it.
Thus, during carboniferous era, the fossil fuels were formed between 360 to 300 million years ago.

Why does energy transfer not always result in phase change?
PLZ HELP!!!
PLZ PLZ HELP!!!!
Answer:
These energy changes are mot changes into kinetic energy . They are changing in bonding energy between the molecules " If heat is coming into a substance during a phase change , then this energy is used to break the bonds between the molecules of the substance .
Explanation:
hope it helps !!
Energy transfer does not always result in phase change because ; Not all energy transfers breaks the bonds between molecules ( i.e. kinetic energy )
What is energy transferEnergy transfer is the movement/transfer of energy from one system to another usually in the form of heat , work or other form of mass transfer.
Not all Energy transfer results in the phase changes because some energy transfers are not Kinetic energies and do not breakup the bond between molecules.
Hence we can conclude that Energy transfer does not always result in phase change because ; Not all energy transfers breaks the bonds between molecules ( i.e. kinetic energy ).

In an atom why don’t the electrons float away ? The float around in the electron cloud but what keeps them from floating away ?
Answer: If an electron is in the electric field of a nucleus, the electron can occupy only certain energy levels. When it is sitting on one of these energy levels, it does not radiate, it does not loose energy.
Clouds are made of water droplets and ice crystals. A cloud's individual particles are so small, Also that warm air rising from the earth's surface is able to keep them floating in the air.
Electron clouds are the energy levels where the probability of getting an electron is maximum. These float due to the small size which results into rising them from the earth's surface.
What are the electron cloud?
An electron cloud can be defined as the region which is surrounding an atomic nucleus in the atom in which there is a high probability of an electron being located.
If an electron, negatively charged particle is in the electric field of a nucleus, then the electron can occupy only certain energy levels in the atom. When it is sitting on one of these certain energy levels, then it does not radiate, and hence does not loose energy.
Electron clouds are made up of water droplets and ice crystals. A cloud's individual particles are so small in size, also that the warm air rising from the earth's surface is able to keep them floating in the air.

"Some plants called epiphytes, or air plants, have adapted to get nutrients from the air.
Some examples of epiphytes in rainforests are mosses, lichens, and orchids. Although
they often live on other plants, they don't take any nutrients from the other plants-they
get what they need straight from the air with special root systems.
There are also some plants called parasitic plants. They grow on other plants, their host
plants. Parasitic plants actually DO take nutrients from their host plants."
Why might the author have capitalized the word "DO"?
A. to point out a similarity
B. to make a contrast
C. to summarize a process
D. to make an argument
Answer:
B.
Explanation:
Prior to the parasite lines, he mentions that epiphytes do not take nutrients from other plants, therefore, by capitalizing the word "do" he is creating emphasis on the contrast between his two statements about plants.
