Which substance is build up in the muscles during robust physical activity that cause cramps?

Carbon dioxide , Water & Energy
Pyruvate
Lactic acid & Energy
Ethanol , Carbon dioxide & Energy

Correct Answer

A. Lactic acid & Energy

Explanation

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".

Which is the respiratory pigment in the human body?

Water
Chlorophyll
Haemoglobin
Plasma

Correct Answer

A. Haemoglobin

Explanation

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.

What is the process of evaporating water from the aerial parts of the plant called?

Respiration
Transportation
Transpiration
None of the above

Correct Answer

A. Transpiration

Explanation

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.

What is the function of Xylem?

To transport water and minerals
To transport water
To translocate food
All of the above

Correct Answer

A. To transport water and minerals

Explanation

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."

Which fluid medium is there in blood?

Plasma
Platelets
Lymph
All of these

Correct Answer

A. Plasma

Explanation

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.

Which instrument can be used to measure blood pressure

Manometer
Anemometer
Sphygmomanometer
Hydrometer

Correct Answer

A. Sphygmomanometer

Explanation

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.

Which vessels carry blood away from the heart to other body organs?

Arteries
Capillaries
Veins
None of the above

Correct Answer

A. Arteries

Explanation

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.

What occurs during anaerobic respiration?

Glucose breaks down without oxygen.
The mitochondria inside the cell works actively.
Respiration proceeds without oxygen.
None of the above

Correct Answer

A. 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."

Name the process that transports soluble products of photosynthesis.

Transpiration
Translocation
Transportation
Respiration

Correct Answer

A. Translocation

Explanation

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.
