The nucleus is a membrane-bound organelle found in eukaryotic cells. It houses the cell's DNA and is responsible for regulating gene expression and controlling cell activities. It is essential for the cell's growth, metabolism, and reproduction.
Most of the mass of a potassium atom is located in its nucleus, which contains protons and neutrons. The electrons in the electron cloud surrounding the nucleus have significantly less mass compared to the nucleus.
A bacterium is a prokaryotic cell because it lacks a nucleus and other membrane-bound organelles like mitochondria or endoplasmic reticulum. Instead, its genetic material is located in the nucleoid region of the cell.
No, radioactive elements will not chemically react differently than non-radioactive elements. The radioactivity of an element is a property of its nucleus and does not affect its chemical behavior.
