How do the nucleus and ribosomes work together to maintain homeostasis

The nucleus contains the cell ‘s DNA and directs the synthesis of ribosomes and proteins.

Found within the nucleoplasm, the nucleolus is a condensed region of chromatin where ribosome synthesis occurs.

Chromatin consists of DNA wrapped around histone proteins and is stored within the nucleoplasm.

Ribosomes are large complexes of protein and ribonucleic acid (RNA) responsible for protein synthesis when DNA from the nucleus is transcribed.

Explanation:

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
