Which of the following statements about the nucleus is not true?
a. the nucleus stores the coded instructions for making the cell’s proteins.
b. the nucleus usually contains a nucleolus region which is where ribosome assembly begins.
c. the nucleus is the site of protein assembly.
d. the nucleus is surrounded by a nuclear envelope that lets materials in and out.

answer;

the nucleus is the cite of protein assembly

explanation;

-the nucleus is an organelle found in eukaryotic cells. inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material. this material is organized as dna molecules, along with a variety of proteins, to form chromosomes. it governs gene expression and facilitates dna replication during the cell cycle.

-it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division).

-protein assembly takes place in the cytoplasm in the structures called ribosomes found out-side the nucleus.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
