Which organelle makes the proteins that are needed by the cell?
cell membrane
golgi apparatus
ribosomes
nucleus

The correct answer will be option-ribosomes

Explanation:

The proteins are synthesized from the mRNA molecule through the process of translation in the ribosome.

The ribosomes are the organelles specialized to perform the process of translation. The organelle is made up of two units called large subunit and the small subunit each composed of the rRNA and the ribosomal proteins.

The ribosomes are present in the cell either attached to the surface of the endoplasmic reticulum or freely in the cytoplasm.  

Thus, option-ribosomes are the correct answer.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
