1.
Nutrition can be defined as the process by which our body obtains food and uses it for growth, metabolism and repair.
Correct Answer
A. True
Explanation
This statement is true because nutrition is indeed the process by which our body obtains food and uses it for growth, metabolism, and repair. Nutrition involves the intake of nutrients from food, such as carbohydrates, proteins, fats, vitamins, and minerals, which are essential for the body's functioning and overall health. These nutrients are broken down and absorbed by the body, providing energy and supporting various bodily processes, including growth, tissue repair, and metabolism. Therefore, the statement accurately defines nutrition.
2.
Nutrition is the science that deals with food and nourishment including:- (Select Three)
Correct Answer(s)
A. Dietary guidelines.
C. Food composition.
D. The roles that various nutrients have in maintaining health.
Explanation
The correct answer is dietary guidelines, food composition, and the roles that various nutrients have in maintaining health. Nutrition is a field of study that focuses on the relationship between food and health. Dietary guidelines provide recommendations for a healthy diet, including the types and amounts of food to consume. Food composition refers to the nutrients and other components found in different foods. Understanding the roles that various nutrients have in maintaining health is important for making informed dietary choices.
3.
Differentiated cells with similar properties aggregate together, to form:-
Correct Answer
A. Tissues
Explanation
Differentiated cells with similar properties have the ability to aggregate together and form tissues. Tissues are groups of cells that work together to perform specific functions in the body. These cells may have similar structures and functions, allowing them to work in coordination and contribute to the overall function of the tissue.
4.
The organs can be classified into TEN organ systems: (Select Ten)
Correct Answer(s)
A. Circulatory.
C. Digestive
D. Endocrine
E. Immune
F. Integumentary (skin)
G. Musculoskeletal
H. Nervous
I. Reproductive
J. Respiratory
K. Urinary
Explanation
The given answer includes ten organ systems: Circulatory, Digestive, Endocrine, Immune, Integumentary (skin), Musculoskeletal, Nervous, Reproductive, Respiratory, and Urinary. These organ systems are responsible for various functions in the body. The circulatory system transports oxygen, nutrients, and hormones throughout the body. The digestive system breaks down food and absorbs nutrients. The endocrine system regulates hormones and metabolism. The immune system defends against pathogens. The integumentary system protects the body from external damage. The musculoskeletal system supports movement and provides structure. The nervous system controls bodily functions and processes sensory information. The reproductive system is responsible for reproduction. The respiratory system facilitates gas exchange. The urinary system filters waste and maintains fluid balance.
5.
All cells in our body maintain the body’s integrity and life through the following activities:- (Select Three)
Correct Answer(s)
B. Taking food from the surrounding environment and excreting its waste back into that environment.
C. Making energy by breaking down these organic nutrients and making new molecules from them.
D. Reproducing themselves.
6.
The essential amino acids, are the building blocks of protein.
Correct Answer
A. True
Explanation
Essential amino acids are indeed the building blocks of protein. They are called "essential" because they cannot be produced by the body and must be obtained through diet. Proteins are made up of chains of amino acids, and these essential amino acids are necessary for the synthesis of proteins in the body. Therefore, the statement is true.
7.
Enzymes play a minor role in the digestion of food, as they are not responsible for the chemical changes that the food undergoes during digestion.
Correct Answer
B. False
Explanation
Enzymes play a major role in the digestion of food, as they are responsible for the chemical changes that the food undergoes during digestion. Enzymes are biological catalysts that help break down complex molecules into simpler ones, allowing the body to absorb and utilize nutrients. Without enzymes, the process of digestion would be inefficient or even impossible. Therefore, the statement that enzymes play a minor role in digestion is false.
8.
The carbohydrates in the brush border are as follows:- (Select Four)
Correct Answer(s)
A. Maltase (also called Glucoamylase)
B. Lactase (also called Beta-galactosidase)
D. Sucrase
E. Isomaltase
Explanation
The brush border is a specialized structure found in the small intestine that contains enzymes responsible for the final breakdown of carbohydrates. Maltase (also called Glucoamylase), Lactase (also called Beta-galactosidase), Sucrase, and Isomaltase are all enzymes present in the brush border. These enzymes help in the digestion and absorption of different types of carbohydrates. Capillaries, on the other hand, are tiny blood vessels that are not directly involved in the breakdown of carbohydrates in the brush border.
9.
The lymphatic system is a major component of the immune system.
Correct Answer
A. True
Explanation
The lymphatic system is indeed a major component of the immune system. It plays a crucial role in defending the body against infections and diseases by producing and transporting white blood cells, known as lymphocytes, which help identify and destroy harmful pathogens. Additionally, the lymphatic system also helps remove waste products and toxins from the body, maintaining overall health and well-being. Therefore, it is correct to say that the lymphatic system is a major component of the immune system.
10.
The lymphatic system has main interrelated functions:- (Select Three)
Correct Answer(s)
A. Removal of excess fluids from body tissues.
B. Absorption of fatty acids and subsequent transport of fat, chyle, and fat-soluble vitamins to the circulatory system.
C. Production of immune cells (such as leucocytes and antibody producing cells called plasma cells)
Explanation
The lymphatic system has three main interrelated functions. Firstly, it removes excess fluids from body tissues, preventing the buildup of fluid and maintaining fluid balance in the body. Secondly, it absorbs fatty acids and transports fat, chyle, and fat-soluble vitamins to the circulatory system, ensuring proper nutrient transport. Lastly, the lymphatic system plays a crucial role in the production of immune cells, such as leucocytes and plasma cells, which are essential for defending the body against infections and diseases.
11.
The lymphatic system acts as a secondary circulatory system, except that it collaborates with red blood cells in lymph nodes to protect the body from being infected by cancer cells, fungi, viruses or bacteria.
Correct Answer
B. False
Explanation
The lymphatic system acts as a secondary circulatory system, but it does not collaborate with red blood cells in lymph nodes to protect the body from being infected by cancer cells, fungi, viruses, or bacteria. The primary role of the lymphatic system is to help maintain fluid balance in the body, remove waste products, and transport immune cells to fight off infections. The lymph nodes, which are part of the lymphatic system, filter lymph fluid and help in the activation of immune responses, but they do not directly collaborate with red blood cells. Therefore, the statement is false.
