in the nucleus.
in the mitochondrium.
in the chloroplast.
free in the cytoplasm.
attached to the rough endoplasmic reticulum.
question 10
the cytoskeleton is composed of three major components, each with distinct functions. which of the following represents the correct order of these components, from smallest to largest size?
a. intermediate filaments, microfilaments, microtubules
b. microfilaments, intermediate filaments, microtubules
c. microtubules, intermediate filaments, microfilaments
d. microtubules, microfilaments, intermediate filaments
e. intermediate filaments, microtubules, microfilaments

Explanation:

Ribosomes are sites of protein - synthesis. In eukaryotic cells, they are found in mitochondria (for mitochondrial protein synthesis), chloroplasts (for chloroplast - specific protein synthesis), free in the cytoplasm, attached to the rough endoplasmic reticulum for protein secretion or membrane - bound proteins. The nucleus does not contain functional ribosomes. For the cytoskeleton components, microfilaments are the smallest (about 7 nm in diameter), intermediate filaments are about 8 - 12 nm in diameter, and microtubules are the largest (about 25 nm in diameter).

Answer:

Question 9: In the nucleus.
Question 10: B. Microfilaments, intermediate filaments, microtubules
