Answer:
C
Explanation:
Conduction is the transfer of heat through direct contact. The correct option is C.
What is conduction?Direct contact between molecules inside a substance allows for the transfer of energy, typically in the form of heat and/or electricity. Conduction can occur in gases, liquids, and solids.
Electrical current or conductivity occurs as a result of electrically charged particles moving across a material.
An ordinary example of conduction is the procedure of heating a pan on a stove. Energy is transferred directly from one molecule to another by conduction. Similar to how one moving ball strikes another in a game of pool to cause the second ball to move, this transfer happens when molecules collide with one another.
Therefore, the correct option is C. direct contact.

Explain why the pulse rate changes during and after exercise. Important words to use are muscle cells, exercise, energy, glucose, oxygen, blood, and cellular respiration.
Answer:
The pulse rate changes during exercise because when we do exercise the demand for oxygen in body is very high as compare to the supply from the environment. To complete the demand the plus rate changes . when we exercise heavily our muscle cells lacks oxygen and respire anaerobically in which glucose broke down into 3 carbon molecule called Pyruvate .
Cheetah have evolved a much higher lung capacity,why
Cheetah need a large lung capacity because they consume a lot of oxygen while sprinting.
Answer:
Cheetahs have evolved a much higher lung capacity than humans; it helps provide oxygen to all the muscles in the body and allows them to run very fast. ... In this case, it is not because they run fast but because they have a large body and must be able to take up oxygen in accordance with their body size.
Which organism is not multicellular and does not display a vertebral column?
A. human
B. koala
C. flatworm
D. paramecium
Answer:
D: Paramecium
Explanation:
Paramecium is a unicellular organism with a shape resembling the sole of a shoe. It ranges from 50 to 300um in size which varies from species to species. It is mostly found in a freshwater environment. It is a single-celled eukaryote belonging to kingdom Protista and is a well-known genus of ciliate protozoa.
7. If any type of rock experiences intense heat and cools it changes into?
Answer:
Metamorphic rock occurs when you take any other type of rock and put them under and , and they twist and meld together. ... If any type of rock experiences intense heat and cools it changes into rock.
Explanation:
Answer: Granite is an igneous rock that forms when magma cools relatively slowly underground. It is usually composed primarily of the minerals quartz, feldspar, and mica. When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss. Slate is another common metamorphic rock that forms from shale.
Explanation: This is correct
Why does warm air rise
Answer:
When we heat air, the molecules jiggle and zip around faster, which causes them to spread out. When a mass of air takes up more space, it has a lower density. ... Warm air rises when it's surrounded by cold air because of its lower density.
Explanation:
hope this helps :)
Answer:
SAMPLE: When we heat air, the molecules jiggle and zip around faster, which causes them to spread out. When a mass of air takes up more space, it has a lower density. ... Warm air rises when it's surrounded by cold air because of its lower density.
Explanation:
What this means is that when it is hot outside, molecules move faster and faster. This propels the molecule up since the molecule cannot handle low density. This is because when molecules occupy space and a molecule is moving very fast, it needs as much space as possible to move.

A transformer in a neon sign contains 20 truns in the primary coil and 80 truns in the secondary coil. Which is greater- the output voltage or the input voltage?
Answer:
The output voltage is greater.
Explanation:
The turns ratio is directly proportional. Vs= Vp X (ns/np)
In this neon sign xformer example it is 80/20 or 4
So secondary voltage for 120 volt primary/line voltage = 480 volt secondary volts.
This is practical in a neon sign as it takes more voltage to start the neon gas excitation.
The output voltage is greater.
Calculation of output voltage:Since A transformer in a neon sign contains 20 turns in the primary coil and 80 turns in the secondary coil.
So here turns ratio should be directly proportional. Vs= Vp X (ns/np)
So, In this neon sign former example it is 80/20 or 4
Thus, secondary voltage for 120 volt primary/line voltage = 480 volt secondary volts.
