Answer : Option C) Rock Cycle.

Explanation : Rock cycle is a basic concept in geology which deals with the time-consuming transitions that occurs through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. It does not involves living organisms in this cycle.

Rest all the other cycle involves living organisms, carbon cycle has indirect impact of humans on it as it deals with the photosynthesis and the metabolism activities.

Oxygen cycle deals with the circulation of the oxygen through various forms in the nature including humans.

Nitrogen cycle involves nitrifying bacteria which converts the atmospheric nitrogen into ammonia and then convert it to nitrites for the use of plants.

Answer:

X  

Explanation:

Assume your diagram is like the one below.

X represents a mitochondrion.

That's where the Tricarboxylic Acid Cycle converts a single glucose molecule into six molecules of CO₂.

W is wrong. It represents a vacuole, which can store both nutrients and waste products for later elimination.

Y is wrong. It represents the nucleolus, which plays a critical role in the synthesis of ribosomes.  

Z is wrong. It represents the cytoplasm, which is where cell processes like glycolysis and protein synthesis take place.

A student placed 19.0 g of glucose (c6h12o6) in a volumetric flask, added enough water to dissolve the glucose by swirling, then
EleoNora [17]
  <span>moles glucose = 19 g / 180 g/mol= 0.105 
M = 0.105 / 0.100 L = 1.05 

moles in 20.0 mL = 1.05 M x 0.0200 L = 0.0216 

New concentration = 0.0216 /0.500 L = 0.0432 M 
moles in 100 mL = 0.100 L x 0.0432 = 0.00432 

mass = 0.00432 x 180 g/mol= 0.778 g</span>

An example of kinetic energy being converted into heat energy
sammy [17]

Answer:

if you drop a water balloon onto the ground, its kinetic energy is converted mostly to thermal energy. If the balloon weighs 1 kilogram and you drop it from about 2 meters, it will heat up by less.

Explanation:

As you say, kinetic energy of large objects can be converted into this thermal energy. For example, if you drop a water balloon onto the ground, its kinetic energy is converted mostly to thermal energy. If the balloon weighs 1 kilogram and you drop it from about 2 meters, it will heat up by less than.
