4. What are the functions of the nucleolus? (Choose all that apply) regulating the cell's interaction with its surroundings
beginning ribosome assembly
translating the code contained by the DNA into the proteins the cell needs for structure and function
converting energy from food into a form the cell can use

The function of the nucleolus includes 'beginning ribosome assembly'.

The nucleoli are eukaryotic organelles located within the cell nucleus that act as ribosome factories, in which the process of transcription (i.e., RNA synthesis) occurs constantly.

The nucleolus serves to make ribosomal subunits and then it sends ribosomal subunits to different cell destinations where they form full ribosomes.

In conclusion, the function of the nucleolus includes 'beginning ribosome assembly'.

B NUCLEOLUS IS WHERE DNA IS STORED

BRAINLIEST M

Explanation:

The nucleolus is the most conspicuous domain in the eukaryotic cell nucleus, whose main function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis. AKA DNA

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
