Life Functions Questions and Answers

1.

Getting Energy From Food Is Called...
- A.
  
  Metabolism
- B.
  
  Transport
- C.
  
  Respiration
- D.
  
  Nutrition
Correct Answer
C. Respiration

Explanation
Respiration is the process by which living organisms obtain energy from food. During respiration, food molecules are broken down in the presence of oxygen, releasing energy in the form of ATP (adenosine triphosphate). This energy is used by the cells for various metabolic activities. Therefore, respiration is the correct answer as it accurately describes the process of obtaining energy from food.

Absorption and circulation of materials is called...
- A.
  
  Transportation
- B.
  
  Homeostasis
- C.
  
  Ingestion
- D.
  
  Metabolism
Correct Answer
A. Transportation

Explanation
Transportation refers to the process of absorption and circulation of materials within an organism. It involves the movement of substances such as nutrients, gases, and waste products across various tissues and organs. This process ensures that essential substances are delivered to the cells and waste products are removed efficiently. Homeostasis refers to the maintenance of a stable internal environment, ingestion refers to the intake of food, and metabolism refers to the chemical reactions that occur within the body. Therefore, transport is the most appropriate term to describe the absorption and circulation of materials.

Sum total of all life functions is...
- A.
  
  Biology
- B.
  
  Respiration
- C.
  
  Digestion
- D.
  
  Metabolism
Correct Answer
D. Metabolism

Explanation
Metabolism refers to all the chemical reactions that occur within an organism to maintain life. It includes processes such as respiration and digestion, which are essential for the breakdown of food and the release of energy. Metabolism also involves other functions like synthesis of molecules, elimination of waste, and regulation of body temperature. Therefore, the sum total of all life functions is metabolism, as it encompasses all the necessary processes for an organism to survive and function properly.

Taking In Food is called...
- A.
  
  Ingestion
- B.
  
  Digestion
- C.
  
  Egestion
- D.
  
  Nutrition
Correct Answer
A. Ingestion

Explanation
Ingestion is the process of taking in food into the body through the mouth. It involves the intake of food and its movement through the digestive system for further processing and absorption of nutrients. Digestion refers to the breakdown of food into simpler forms, while egestion is the elimination of waste from the body. Nutrition, on the other hand, is the overall process of obtaining and utilizing nutrients from food. Therefore, the correct term for taking in food is ingestion.

Maintaining a Stable internal environment
- A.
  
  Metabolism
- B.
  
  Transport
- C.
  
  Homeostasis
- D.
  
  Organism
Correct Answer
C. Homeostasis

Explanation
Homeostasis refers to the ability of an organism to maintain a stable internal environment despite changes in the external environment. It involves various physiological processes such as regulation of body temperature, pH levels, blood sugar levels, and water balance. Through homeostasis, the body can respond and adapt to external stimuli to ensure optimal functioning. This process is crucial for the survival and proper functioning of organisms.

6.

Breaking Down Food is called...
- A.
  
  Digestion
- B.
  
  Homeostasis
- C.
  
  Nutrition
- D.
  
  Biology
Correct Answer
A. Digestion

Explanation
Digestion is the process of breaking down food into smaller molecules that can be absorbed and utilized by the body. It involves mechanical and chemical processes, such as chewing, stomach contractions, and the action of enzymes, to break down complex substances into simpler forms. Homeostasis refers to the body's ability to maintain a stable internal environment. Nutrition is the process of obtaining and using food for growth and energy. Biology is the scientific study of living organisms.

Getting Rid Of Solid Waste Products is called...
- A.
  
  Egestion
- B.
  
  Organism
- C.
  
  Respiration
- D.
  
  Metabolism
Correct Answer
A. Egestion

Explanation
Egestion refers to the process of eliminating solid waste products from the body. It is commonly associated with the excretion of undigested food material through the rectum. This process is essential for maintaining the overall health and proper functioning of the digestive system. Respiration, on the other hand, is the process of exchanging gases, metabolism refers to the chemical reactions that occur in the body to sustain life, and an organism is a living entity.

Getting And Using Food is called...
- A.
  
  Biology
- B.
  
  Homeostasis
- C.
  
  Transport
- D.
  
  Nutrition
Correct Answer
D. Nutrition

Explanation
Nutrition is the correct answer because it refers to the process of obtaining and using food by living organisms. It involves the intake, digestion, absorption, and utilization of nutrients for energy, growth, and maintenance of bodily functions. Biology is the study of living organisms, homeostasis refers to the maintenance of a stable internal environment, and transport refers to the movement of substances within an organism. While these concepts are related to nutrition, they do not encompass the entirety of the process of getting and using food.

The Study Of Life is called...
- A.
  
  Transport
- B.
  
  Ingestion
- C.
  
  Biology
- D.
  
  Respiration
Correct Answer
C. Biology

Explanation
The study of life is called biology. Biology is the branch of science that focuses on the study of living organisms, including their structure, function, growth, evolution, and distribution. It encompasses various sub-disciplines such as botany, zoology, microbiology, and genetics. Through the study of biology, scientists gain a better understanding of the complexity and diversity of life on Earth, as well as the interconnectedness of all living things.

What is the primary function of respiration in living organisms?
- A.
  
  To absorb nutrients from the environment
- B.
  
  To convert glucose and oxygen into energy
- C.
  
  To eliminate waste products from the body
- D.
  
  To transport oxygen to cells
Correct Answer
B. To convert glucose and oxygen into energy

Explanation
Respiration is a critical life function in all living organisms, involving the biochemical process of converting glucose and oxygen into energy. This energy, in the form of ATP (adenosine triphosphate), is essential for powering various cellular activities and physiological processes necessary for survival. The process typically occurs in the mitochondria of cells through a series of reactions known as cellular respiration. This includes glycolysis, the Krebs cycle, and oxidative phosphorylation, each contributing to the efficient production of ATP.
