e. they are composed of two subunits. quizzlet

A. They function within the nucleus.

Explanation:

Ribosomes are tiny particles found in both prokaryotic and eukaryotic cells. In eukaryotic cells, ribosomes are found free in the cytoplasm or are attached to the surface of the rough endoplasmic reticulum. Ribosomes consist of RNA and proteins and are synthesized by the nucleolus. Each ribosome has two main components: a large subunit and a small subunit.

Ribosomes contain the enzyme which is required to form peptide bonds between amino acids for protein synthesis. Therefore, ribosomes function in the cytoplasm and on the surface of the rough endoplasmic reticulum. They do not perform protein synthesis in the nucleus.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
