Explanation

• Lactic acid is a natural preservative found in fermented foods like yogurt, cheese, and sauerkraut.
• It's produced during the fermentation process when bacteria like Lactobacillus convert sugars into acid.

Explanation

In solids, heat transfer occurs primarily through conduction, where vibrations and collisions of particles (atoms or molecules) transfer energy from one point to another.

Explanation

• Heat is a form of energy that is transferred from one body to another due to a temperature difference.
• It is a type of kinetic energy that is transferred through the motion of particles.

Explanation

• Carnivores are animals that eat only meat, primarily from other animals.
• Examples of carnivores include lions, tigers, bears, wolves, and sharks.

Explanation

Plants release more Carbon Dioxide (CO2) at night due to respiration.

Explanation

• Heat is measured in Joules (J), which is the unit of energy.
• Heat is a form of energy transferred from one body to another due to a temperature difference.

Explanation

Weather satellites are used to provide weather forecasting and monitoring of weather patterns, climate change.

Explanation

• Plants don’t need shelter but they need air.
• Air provides the necessary carbon dioxide for photosynthesis and oxygen for respiration.

Explanation

• Water (H2O) is a compound made up of two hydrogen atoms and one oxygen atom.
• It is a chemical combination of two different elements, which is the definition of a compound.

Explanation

• Atoms that gain electrons become negatively charged ions.
• These are known as Anions.
