- D.
6CO2+6H2O_SUNLIGHT_C6H12O6+6O2
Correct Answer
D. 6CO2+6H2O_SUNLIGHT_C6H12O6+6O2Explanation
The correct equation for photosynthesis is 6CO2+6H2O_SUNLIGHT_C6H12O6+6O2. This equation represents the process of photosynthesis, where carbon dioxide (CO2) and water (H2O) react in the presence of sunlight to produce glucose (C6H12O6) and oxygen (O2).Rate this question:

Where does the energy for photosynthesis come from?
- A.
ATP
- B.
Sunlight
- C.
Water
- D.
Energy
Correct Answer
B. SunlightExplanation
Photosynthesis is the process by which plants convert sunlight into chemical energy in the form of glucose. Sunlight is essential for photosynthesis as it provides the energy needed to power the chemical reactions that occur in the chloroplasts of plant cells. Through a series of complex reactions, sunlight is absorbed by pigments such as chlorophyll, which then initiates the conversion of carbon dioxide and water into glucose and oxygen. Therefore, sunlight is the ultimate source of energy for photosynthesis.Rate this question:

How are the formulas of photosynthesis and respiration different? They differ because...
- A.
Respiration releases energy and photosynthesis releases carbonhydrates.
- B.
Respiration releases oxgen and photosynthesis releases carbon dioxide.
- C.
Respiration take ATP.
- D.
Respiration releases sunlight and photosynthesis release carbon dioxide.
Correct Answer
B. Respiration releases oxgen and pHotosynthesis releases carbon dioxide.Explanation
Photosynthesis and respiration are two opposite processes that occur in plants. During photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose (a carbohydrate) and release oxygen as a byproduct. On the other hand, respiration is the process by which cells break down glucose to release energy, using oxygen and producing carbon dioxide as a waste product. Therefore, the correct answer states that respiration releases oxygen and photosynthesis releases carbon dioxide, highlighting the contrasting roles of these processes in terms of gas exchange.Rate this question:

What is photosynthesis and respiration?
- A.
Photosynthesis is the process by which respiration is the act of inhaling and exhaling.respiration is the act of inhaling and exhaling.
- B.
Photosynthesis i the process by which carbonhydrates by plants and some other organism use ligth energy to power chemical:: respiration is the act or process of inhaling and exhaling.
- C.
Photosynthsis is the process food which plants and some other this to reproduce.respiration is the act of inhaling and exhaling
- D.
Photosynthesis is the process by which respiration is the act of ATP .respiration is the act of inhaling and exhaling
Correct Answer
B. pHotosynthesis i the process by which carbonhydrates by plants and some other organism use ligth energy to power chemical:: respiration is the act or process of inhaling and exhaling.Explanation
The correct answer explains that photosynthesis is the process in which carbohydrates are produced by plants and other organisms using light energy to power chemical reactions. On the other hand, respiration is the act or process of inhaling and exhaling.Rate this question:

What are the main products of respiration?
- A.
Bacteria
- B.
Plants
- C.
Fossil fuels
- D.
CO2
- E.
Alll the above
Correct Answer
E. Alll the aboveExplanation
The main products of respiration are bacteria, plants, fossil fuels, and CO2. Respiration is a process that occurs in living organisms, including bacteria and plants, where they break down organic molecules to release energy. Fossil fuels, such as coal, oil, and natural gas, are formed from the remains of plants and animals that underwent millions of years of heat and pressure. CO2, or carbon dioxide, is a waste product of respiration and is released into the atmosphere. Therefore, all of the options listed are correct as they are all products of respiration.Rate this question:

What are the two types of respiration?
- A.
Areobic and Anaerobic
- B.
ATP
- C.
An adenosine base
- D.
Sun → Autotroph → Heterotroph
- E.
None the above
Correct Answer
A. Areobic and AnaerobicExplanation
The correct answer is "Aerobic and Anaerobic." Aerobic respiration is a type of respiration that occurs in the presence of oxygen, producing carbon dioxide and water as byproducts. Anaerobic respiration, on the other hand, occurs in the absence of oxygen and produces lactic acid or ethanol as byproducts. These two types of respiration are essential for energy production in living organisms.Rate this question:

Complete the following equation of reation for respiration? C6H12O6+6O2 -----> +
- A.
6CO2+6H2O+LIGHT--> C6H12O6+6O2
- B.
6CO2+6H2O+FOOD ---> H6H15O6+3O2
- C.
H6H15O6+3O2--> ENERGY+6CO2+6H2O
- D.
None the above
Correct Answer
A. 6CO2+6H2O+LIGHT--> C6H12O6+6O2Explanation
The given equation represents the process of photosynthesis, where carbon dioxide (6CO2) and water (6H2O) are converted into glucose (C6H12O6) and oxygen (6O2) in the presence of light. This is the process by which plants and other organisms convert sunlight into energy.Rate this question:

Which organsims undergo respiration?
- A.
Plants
- B.
Animals
- C.
Bacterica
- D.
All the above
Correct Answer
D. All the aboveExplanation
All organisms undergo respiration, including plants, animals, and bacteria. Respiration is the process of converting oxygen into energy, which is essential for the survival and functioning of all living organisms. Plants undergo respiration through tiny pores called stomata in their leaves, while animals respire through organs like lungs or gills. Bacteria also undergo respiration to generate energy for their metabolic processes. Therefore, the correct answer is "All the above."Rate this question:

How often do we use photosynthesis and respiration in our everyday life?
- A.
Never
- B.
Always
- C.
Sometimes
- D.
Hardly ever
- E.
none of the above
Correct Answer
B. AlwaysExplanation
Photosynthesis and respiration are vital processes that occur in plants and animals, including humans. Photosynthesis is responsible for converting sunlight into energy-rich molecules, while respiration helps release energy from these molecules. As humans rely on plants for food and oxygen, we indirectly depend on photosynthesis for our everyday life. Additionally, respiration is a continuous process that takes place in our cells, providing the energy necessary for various bodily functions. Therefore, the correct answer is "always" as these processes are constantly occurring in our everyday life.Rate this question:
