To be accepted, a scientific argument must first proved it's solidity and validity and critiques from other expert is usually the best way to explain both the solidity and the validity of a scientific argument

The answer is i<span>t allows for specialized functions in each of the compartments.

There are 6 molecules of O2.
"O2" is the formula for one molecule oxygen, which has 2 atoms.
The subscript (small) "2" tells you how many atoms are in the molecule.
The coefficient is the big number tells you the number of molecules.
In 6O2, there are 12 atoms in total (6 molecules of 2 atoms each).
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.
The right answers are complete gut and one-way gut.
Food is ingested by the mouth, where it is chewed and then thrown into the esophagus during swallowing.
After, there is food in the stomach
Then there is digestive absorption of nutrients in the small intestine
After that, Waste disposal and reabsorption of water in the colon (large intestine)
And finally, stool passes through the rectum (anus), where it is stored before defecation, induced by a reflex mechanism.
