A sign of coral reef distress is called
Answer:
Coral Bleaching
Explanation:
"When water is too warm, corals will expel the algae living in their tissues causing the coral to turn completely white. This is called coral bleaching. When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality."

In what ways does carbon enter the hydrosphere?
Answer: When oxygen is present, aerobic respiration occurs, which releases carbon dioxide into the surrounding air or water. Otherwise, anaerobic respiration occurs and releases methane into the surrounding environment, which eventually makes its way into the atmosphere or hydrosphere.
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

Which parts of the water cycle the water molecules to give away heat energy?
Answer:
evaporation i think but im not sure
Explanation:
Answer:
condensation
Explanation:
Precipitation, runoff, infiltration, and ground water. Is the source of energy that drives earths water cycle. The sun. As heat energy was added to the water, it changed states from. A liquid to a gas. This gas is called water vapor. As more energy is added to the water, the water molecules move.
Please please please please help me I’m have so much trouble on this please help
Answer:
75%
Explanation:
3/4 of the table have at least one capital B in it, which means it's the dominant trait. This will show up over the recessive trait (b), so this means 3/4 of the offspring will have brown eyes, or 75%. Hope this helps!

Answer:
glycolysis
Explanation:
The first stage of cellular respiration, called glycolysis, takes place in the cytoplasm. In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP.
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.

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.
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 .
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.
