Question: Below is a list of functions performed by organisms. Examine the list, then answer the question that follows.
gas exchange
intake of nutrients
disposal of wastes
stimulus response
reproduction
How do these functions compare between single-celled and multi-celled organisms?
A. Single-celled organisms can perform all of these functions, while multi-celled organisms can perform only some of these functions.
B. Single-celled organisms must perform all of these functions with one cell, while multi-celled organisms can have specialized cells for different functions.
C. Single-celled organisms can perform only some of these functions, while multi-celled organisms can perform all of these functions.
D. Neither single-celled organisms nor multi-celled organisms can perform all of these necessary functions.
Answer:
Option B, Single-celled organisms must perform all of these functions with one cell, while multi-celled organisms can have specialized cells for different functions.
Explanation:
All these functions are performed by both single celled and multi-cellular organism. A single cell has several microscopic organelles that performs specific functions while a multi - celled organism has different body organs/tissues to perform specialized function separately.
A cell exchange gas through the cellular membrane, intake nutrients through engulfing, dispose waste by lysosomes, stimulus response by sensory hairy structure and reproduction through cell division
Hence, option B is correct.
Presbyopia is age-related farsightedness due to hardening of the lens of the eye that causes the eye to focus light behind rather than on the retina when looking at nearby/close objects.
