Question

Which of the following words are part spir mean?
A) float
B) breathe
C) happen

Answer 1

The word 'breathe' is associated with the concept of 'to breathe', relevant to the biological process of respiration. Oxygen is inhaled into the lungs and carbon dioxide is exhaled during the gas exchange process, which is crucial for providing oxygen to cells and removing carbon dioxide waste.

Step-by-step explanation:

The word that has a part meaning 'to breathe' is 'breathe'. This relates to biology and is connected to the process of respiration, where oxygen is inhaled into the lungs and carbon dioxide is exhaled. Understanding this is critical when studying how the body utilizes oxygen and eliminates carbon dioxide during the gas exchange process.

Gas Exchange Process

During the gas exchange process, oxygen and carbon dioxide flow in opposite directions. Oxygen enters the blood from the alveoli (air sacs in the lungs), while carbon dioxide, a waste product of metabolism, exits the blood and is expelled from the body.

Reason for Gas Exchange

This exchange is necessary because oxygen is essential for the production of energy in the body's cells, and carbon dioxide needs to be removed to prevent toxicity. The efficiency of this process is vital for the health and proper function of an organism.

Answer 2

Spir, or spiro, is Latin and is defined as to breathe, so your answer would be B) breathe. :)
