Which of the following sensory functions allows organisms to detect and respond to environmental changes?

Detailed Solution for Test: Organisms and Cells -2 - Question 3
Sensitivity is the sensory function that enables organisms to detect and respond to environmental changes. Organisms have evolved various senses such as taste, touch, hearing, smell, sight, and balance to perceive and react to stimuli in their surroundings. These sensory abilities are vital for survival, helping organisms navigate their environment, find food, avoid danger, and interact with other organisms.

How does respiration differ from breathing?
Detailed Solution for Test: Organisms and Cells -2 - Question 5
Respiration is a biochemical process that involves releasing energy from food, requiring oxygen, and producing carbon dioxide. On the other hand, breathing is the physical process of taking in air (oxygen) and expelling carbon dioxide. While respiration is a chemical process that occurs within cells to produce energy, breathing is the mechanical process of inhaling and exhaling air. ---

Why do root cells in plants lack chloroplasts?
Detailed Solution for Test: Organisms and Cells -2 - Question 11
Root cells in plants lack chloroplasts because they are usually located underground where there is no light available for photosynthesis. Since chloroplasts require light to carry out photosynthesis, it is not necessary for root cells to contain chloroplasts as their primary function is to absorb water and nutrients from the soil to support the plant's growth.
