Question

Arrange the following in order starting from the smallest:

A) Ribosome
B) Mitochondrion
C) Nucleus
D) Starch grain
E) Trachea cell
F) Stomach

Answer 1

The correct order from smallest to largest: Ribosome, Starch grain, Mitochondrion, Nucleus, Trachea cell, Stomach. Ribosomes are the smallest structures involved in protein synthesis, while the stomach, an organ, is the largest in the list.

Step-by-step explanation:

To arrange the items from the smallest to the largest, we must consider their typical size scales in biological terms. The correct order starting from the smallest is as follows:

1. Ribosome
2. Starch grain
3. Mitochondrion
4. Nucleus
5. Trachea cell
6. Stomach

Ribosomes are macromolecular machines involved in protein synthesis and typically measure about 20 nm across. Starch grains can vary in size but are usually larger than ribosomes and can be visible under a light microscope. Mitochondria are larger than starch grains and are often described as the power plants of the cell because they generate most of the cell's supply of adenosine triphosphate (ATP), necessary for energy transfer.

The nucleus is an organelle that houses DNA and is larger than a mitochondrion. A trachea cell is a type of cell that would make up part of the trachea in the respiratory system, and it is larger than the organelles contained within. Finally, the stomach is an organ and is the largest of the items listed.
