Questions and Answers

1.

The vitamin which is very liable and easily destroyed during cooking as well as storage is
- A.
  
  Vitamin A
- B.
  
  Vitamin B
- C.
  
  Vitamin C
- D.
  
  Vitamin K
Correct Answer
C. Vitamin C

Explanation
Vitamin C is a water-soluble vitamin that is highly sensitive to heat, light, and air. It is easily destroyed during cooking as well as storage due to its instability. When exposed to these factors, such as high temperatures during cooking or prolonged storage, the vitamin breaks down and loses its potency. Therefore, it is important to consume foods rich in vitamin C in their raw or minimally processed form to ensure maximum nutritional benefits.

The compound used in anti-malarial drug is
- A.
  
  Aspirin
- B.
  
  Neoprene
- C.
  
  Isoprene
- D.
  
  Chloroquin
Correct Answer
D. Chloroquin

Explanation
Chloroquin is the correct answer because it is a well-known compound used in anti-malarial drugs. It is an effective treatment for malaria and works by preventing the growth and replication of the malaria parasites in the body. Chloroquin has been used for many years and is still used today in certain regions where malaria is prevalent. It is a widely recognized and trusted compound in the field of malaria treatment.

Which of the following is a skin disease?
- A.
  
  Anaemia
- B.
  
  Pellagra
- C.
  
  Osteomalacia
- D.
  
  Rickets
Correct Answer
B. Pellagra

Explanation
Pellagra is a skin disease caused by a deficiency in niacin (vitamin B3) and tryptophan. It is characterized by symptoms such as dermatitis, diarrhea, dementia, and death if left untreated. This disease mainly affects areas of the body exposed to the sun, resulting in skin rashes, redness, and sensitivity. Other symptoms may include digestive problems, mental confusion, and fatigue. Therefore, pellagra is the correct answer as it is a well-known skin disease caused by a specific deficiency.

The richest source of vitamin D is
- A.
  
  Cod liver oil
- B.
  
  Spinach
- C.
  
  Milk
- D.
  
  Cheese
Correct Answer
A. Cod liver oil

Explanation
Cod liver oil is the richest source of vitamin D because it contains high levels of this essential nutrient. Vitamin D is crucial for maintaining healthy bones and teeth, as well as supporting the immune system. While spinach, milk, and cheese are all nutritious foods, they do not contain as much vitamin D as cod liver oil. Therefore, cod liver oil is the best choice for obtaining a significant amount of vitamin D.

Which of the following tests helps in diagnosis of cancer?
- A.
  
  X-ray
- B.
  
  Urine test
- C.
  
  Blood test
- D.
  
  Biopsy test
Correct Answer
D. Biopsy test

Explanation
The biopsy test helps in the diagnosis of cancer by removing a small sample of tissue or cells from the affected area and examining them under a microscope. This test allows doctors to determine whether the cells are cancerous or benign, providing a definitive diagnosis. X-ray, urine test, and blood test may provide some indications or abnormalities, but they are not specific to cancer diagnosis.

Plants synthesis protein from
- A.
  
  Starch
- B.
  
  Sugar
- C.
  
  Amino acids
- D.
  
  Fatty acids
Correct Answer
C. Amino acids

Explanation
Plants synthesize protein from amino acids. Amino acids are the building blocks of proteins and are obtained through various processes such as nitrogen fixation, absorption from the soil, and breakdown of stored proteins. Once obtained, plants use these amino acids to synthesize proteins through a process called translation. Proteins play crucial roles in plant growth, development, and various metabolic processes, making amino acids essential for plant survival and functioning.

Plants absorb dissolved nitrates from soil and convert them into
- A.
  
  Free nitrogen
- B.
  
  Urea
- C.
  
  Ammonia
- D.
  
  Proteins
Correct Answer
A. Free nitrogen

Explanation
Plants absorb dissolved nitrates from the soil and convert them into free nitrogen. This process is known as nitrogen fixation. Free nitrogen is an essential nutrient for plants, and it plays a crucial role in their growth and development. Nitrogen fixation is performed by certain bacteria living in the root nodules of legume plants, such as peas and beans. These bacteria have the ability to convert atmospheric nitrogen into a form that plants can use. This conversion process allows plants to obtain the necessary nitrogen for protein synthesis and other vital biological processes.

One of the following is not a function of bones.
- A.
  
  Place for muscle attachment
- B.
  
  Protection of vital organs
- C.
  
  Secretion of hormones for calcium regulation in blood and bones
- D.
  
  Production of blood corpuscles
Correct Answer
C. Secretion of hormones for calcium regulation in blood and bones

Explanation
Bones do not secrete hormones for calcium regulation in blood and bones. This function is primarily carried out by the endocrine system, specifically the parathyroid glands, which release parathyroid hormone (PTH) to regulate calcium levels. Bones do play a role in calcium regulation, but this is through the process of bone remodeling, where calcium is stored and released as needed.

Photo-oxidation is
- A.
  
  Photorespiration
- B.
  
  Photolysis
- C.
  
  Light and oxygen induced breakdown
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
The correct answer is "All of the above." Photo-oxidation refers to the process in which a substance undergoes oxidation due to the action of light and oxygen. It involves the breakdown of molecules through photorespiration, which is a metabolic pathway that occurs in plants under high oxygen and light conditions. Additionally, photolysis refers to the splitting of a molecule into smaller parts due to the absorption of light energy. Therefore, all three options accurately describe photo-oxidation.

Proces of cell division can take place by
- A.
  
  Heterosis
- B.
  
  Fusion
- C.
  
  Mitosis
- D.
  
  None of these
Correct Answer
C. Mitosis

Explanation
Mitosis is the correct answer because it is the process of cell division in which a single cell divides into two identical daughter cells. During mitosis, the cell's DNA is replicated and distributed equally between the two daughter cells. This process is essential for growth, repair, and maintenance of multicellular organisms. Heterosis refers to the phenomenon where the offspring of two different individuals show improved traits compared to their parents, while fusion is the process of merging two separate cells or organisms into one. Therefore, neither heterosis nor fusion accurately describe the process of cell division.
