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.

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

gulaghasi [49]

Answer:

a. Acetyl-CoA

Explanation:

Pyruvate is decarboxylated in the matrix of mitochondria and loses its carbon as CO2. This decarboxylation is accompanied by its oxidation as well. This process of oxidative decarboxylation of pyruvate is catalyzed by an enzyme complex. It is called the pyruvate dehydrogenase enzyme complex. NAD+ accepts the released electrons and pyruvate is converted into energy-rich acetyl CoA which in turn enters into the Kreb's cycle.

Which qualities describe the entire open-ocean zone? Check all that apply. few nutrients

uysha [10]

<u>Answer:</u>

- few nutrients

- high pressure

- low temperatures

<u>Explanation:</u>

1. Few nutrients: open-ocean zone is located way far from the land, which is the main source of the essential nutrients.

2. High pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.

3. Ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface.

4. Varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.

5. Low temperatures: the temperature of open-ocean zone ranges from a low of -2°C to an average of 17°C.

What are molecules that enzymes break apart or put together?

Dvinal [7]

Other types of enzymes can put atoms and molecules together. Breaking molecules apart and putting molecules together is what enzymes do, and there is a specific enzyme for each chemical reaction needed to make the cell work properly.
