You must choose all three of the correct answers.
Which of the following are examples of characteristics that scientists use to classify organisms into kingdoms?
Responses
How the organism obtains food
Presence or absence of cell structures like a nucleus
Radial or bilateral symmetry
Presence of a notochord or backbone
How many cells the organism has
- How the organism obtains food
- Presence or absence of cell structures like a nucleus
- Presence of a notochord or backbone
The correct answers are:
1. How the organism obtains food - This is an important characteristic used to classify organisms into kingdoms as it distinguishes between autotrophs (organisms that produce their own food) and heterotrophs (organisms that obtain food from other sources).
2. Presence or absence of cell structures like a nucleus - This characteristic helps categorize organisms into different kingdoms, such as prokaryotes (organisms without a nucleus) and eukaryotes (organisms with a nucleus).
3. How many cells the organism has - The number of cells an organism has is another crucial characteristic used to classify it into different kingdoms, such as unicellular (having a single cell) or multicellular (having multiple cells).
The other options, radial or bilateral symmetry and presence of a notochord or backbone, are characteristics used to classify animals into different phyla or classes, rather than kingdoms.
