Muscles in a kangaroo’s legs work as a result of the way in which the cells that make up the muscle work. which component of cell theory does this best illustrate?

The correct answer is -

Cells are considered as the fundamental structural and functional unit of all life forms.

As per the given information in the question, muscles in the legs of kangaroo function due to the way in which the cells present in the muscles work.

This indicates that cells are the basic structural and functional unit of all life forms.

This is one of the three components of cell theory, which was given by Schleiden and Schwann.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
