Options are not provided in the question. The complete question is as following:

During which changes of state does the motion of the atoms decrease?

A. melting and deposition

B. freezing and condensation

C. condensation and evaporation

D. vaporization and sublimation

Answer:

B. freezing and condensation

Explanation:

Matter exist in three form - solid, liquid and gas. The intermolecular force and motion of atom are inversely proportional, which means Greater the intermolecular force of attraction, slower will be the molecular motion.

The intermolecular forces of attraction decrease from solid to gas and solid has the strongest intermolecular forces. Thus, motion of the atom decrease in freezing and condensation.

Freezing changes the state from liquid to solid and condensation changes the state from gas to liquid.

Hence, the correct option is B.

During the day, plants produce

Gekata [30.6K]

Answer:

During the day, plants produce (oxygen) by splitting water molecules in the light-dependent reactions of photosynthesis. At the same time, plants use cellular respiration to produce some of the (carbon dioxide) needed by the light-independent reactions to make sugars. During the night, plants produce (carbon dioxide, but not oxygen) because (only cellular respiration) takes place.

Explanation:

I will try to explain you, why is this the correct answer. During the night, there is only cellular respiration. Let me give you equation to understand the concept better. The equation of cellular respiration is: C₆H₁₂O₆ + 6O₂ + 6H₂O -> 6CO₂ + 12H₂O + ATP (energy) .. During the cellular respiration, the organism is making carbon dioxide, water and energy from glucose and oxygen. The plants are using oxygen during the night and making carbon dioxide.

I hope I helped you. I will be really happy, If you mark my question as brainliest.

Masja [62]

People with O+ blood cannot donate their blood to negative blood types, while people with O- blood can donate to any blood type. This makes them the "universal donor." However, they can only receive O- blood.

timurjin [86]

Answer:

Macro-molecules are used in the body after the conversion of micro-molecules.

Explanation:

Macro-molecules such as protein, carbohydrates and fats etc are bigger in size which can not be absorbed by the cell of the body so these Macro-molecules first broken down into micro-molecules such as amino acids, glucose and fatty acids etc. Protein is converted into amino acids, carbohydrates is converted into glucose and fats is converted into fatty acids by the action of different enzymes. These micro-molecules are used by the cell in order to generate energy.
