Which of the following converts a large amount of energy in the form of ATP?
- A.
Chloroplast
- B.
Nucleus
- C.
Cytoplasm
- D.
Mitochondria
Correct Answer
D. MitochondriaExplanation
Mitochondria convert a large amount of energy in the form of ATP. This is because mitochondria are the powerhouses of the cell and are responsible for cellular respiration, a process that generates ATP through the breakdown of glucose and other molecules. ATP is the main energy currency of the cell, providing energy for various cellular processes.Rate this question:

Which substance is build up in the muscles during robust physical activity that cause cramps?
- A.
Carbon dioxide , Water & Energy
- B.
Pyruvate
- C.
Lactic acid & Energy
- D.
Ethanol , Carbon dioxide & Energy
Correct Answer
C. Lactic acid & EnergyExplanation
During robust physical activity, the muscles require a lot of energy to perform. This energy is produced through a process called glycolysis, where glucose is broken down into pyruvate. However, when there is not enough oxygen available, pyruvate is converted into lactic acid instead. This lactic acid builds up in the muscles and can cause cramps. Therefore, the correct answer is "Lactic acid & Energy".Rate this question:

What occurs during anaerobic respiration?
- A.
Glucose breaks down without oxygen.
- B.
The mitochondria inside the cell works actively.
- C.
Respiration proceeds without oxygen.
- D.
None of the above
Correct Answer
C. Respiration proceeds without oxygen.Explanation
During anaerobic respiration, the process of respiration takes place without the presence of oxygen. This means that glucose is broken down in the absence of oxygen, resulting in the production of energy in the form of ATP. This process occurs in the cytoplasm of cells and is commonly seen in microorganisms and muscle cells when oxygen is limited or not available. The mitochondria, which are responsible for aerobic respiration, do not play an active role during anaerobic respiration. Therefore, the correct answer is "Respiration proceeds without oxygen."Rate this question:

What is the function of Xylem?
- A.
To transport water and minerals
- B.
To transport water
- C.
To translocate food
- D.
All of the above
Correct Answer
A. To transport water and mineralsExplanation
Xylem is a specialized tissue in plants that is responsible for transporting water and minerals from the roots to the other parts of the plant. It consists of long, hollow cells called vessels that allow for efficient movement of water and dissolved nutrients. Therefore, the correct answer is "To transport water and minerals."Rate this question:

- Which is the respiratory pigment in the human body?
- A.
Water
- B.
Chlorophyll
- C.
Haemoglobin
- D.
Plasma
Correct Answer
C. HaemoglobinExplanation
Haemoglobin is the correct answer because it is the respiratory pigment in the human body. Haemoglobin is a protein found in red blood cells that binds to oxygen in the lungs and carries it to the body's tissues. It also helps transport carbon dioxide from the tissues back to the lungs to be exhaled. Chlorophyll is a pigment found in plants that is responsible for photosynthesis, not respiration. Water and plasma are not respiratory pigments.Rate this question:

Which fluid medium is there in blood?
- A.
Plasma
- B.
Platelets
- C.
Lymph
- D.
All of these
Correct Answer
A. PlasmaExplanation
Plasma is the fluid medium in blood. It is a yellowish liquid that makes up about 55% of the blood's total volume. Plasma carries various substances such as nutrients, hormones, waste products, and antibodies throughout the body. It also plays a crucial role in maintaining blood pressure and regulating body temperature. Lymph is a different fluid that is found outside of the blood vessels, while platelets are cell fragments involved in blood clotting. Therefore, the correct answer is plasma.Rate this question:

- Which instrument can be used to measure blood pressure
- A.
Manometer
- B.
Anemometer
- C.
Sphygmomanometer
- D.
Hydrometer
Correct Answer
C. SpHygmomanometerExplanation
A sphygmomanometer is a medical instrument specifically designed to measure blood pressure. It consists of an inflatable cuff that is wrapped around the upper arm and connected to a pressure gauge. The cuff is inflated to temporarily stop the blood flow in the arteries, and then slowly released while the pressure is measured. This allows healthcare professionals to determine the systolic and diastolic blood pressure readings, which are important indicators of cardiovascular health. Therefore, a sphygmomanometer is the correct instrument for measuring blood pressure.Rate this question:

- Which vessels carry blood away from the heart to other body organs?
- A.
Arteries
- B.
Capillaries
- C.
Veins
- D.
None of the above
Correct Answer
A. ArteriesExplanation
Arteries carry blood away from the heart to other body organs. They have thick, elastic walls that help to maintain blood pressure and allow for the efficient transport of oxygenated blood to the tissues. Veins, on the other hand, carry blood back to the heart, while capillaries are tiny blood vessels that connect arteries and veins, allowing for the exchange of nutrients and waste products between the blood and the surrounding tissues.Rate this question:

What is the process of evaporating water from the aerial parts of the plant called?
- A.
Respiration
- B.
Transportation
- C.
Transpiration
- D.
None of the above
Correct Answer
C. TranspirationExplanation
Transpiration is the correct answer because it refers to the process of water evaporating from the aerial parts of a plant, such as the leaves, stems, and flowers. During transpiration, water is drawn up from the roots to the leaves through the xylem vessels and then released into the atmosphere through small openings called stomata. This process helps to regulate the plant's temperature, transport nutrients, and maintain its structure. Respiration refers to the process of converting stored energy into usable forms, while transportation is not a term used to describe the evaporation of water from plants.Rate this question:

- Name the process that transports soluble products of photosynthesis.
- A.
Transpiration
- B.
Translocation
- C.
Transportation
- D.
Respiration
Correct Answer
B. TranslocationExplanation
Translocation is the process that transports soluble products of photosynthesis. During translocation, the sugars produced in the leaves during photosynthesis are transported to other parts of the plant, such as the roots, stems, and fruits. This process occurs through the phloem, which is a specialized tissue responsible for the transportation of organic compounds in plants. Translocation is essential for distributing nutrients and energy throughout the plant, allowing it to grow and function properly.Rate this question:
