- What occurs during the stage of mitosis that is shown in the diagram above Select all that apply OSster chromatids are separated by the spinde fibers OOvomosomes de-condense OCentrioles move to opposite poles OSpinde fbers disappear OChromosomes condere ONuclear emvelope reforms O Nuclear emvelope disappearsWhen considering the stages of the cell cycle, which stage is best associated with cells that do not divide, such as nerve cells? G1 phase M phase O None - all cells divide S phase G2 phase GO phase Pickles are often preserved in a 20-30% salt solution called brine. How does brine prevent contamination by microorganisms? Bacteria can't survive in hypotonic solutions because of the added pressure of the water they take in causing them to burst. O Bacteria can't survive in a hypertonic solution because they lose too much water and die. O The high salt concentration increases the pH of the environment, making it unfavorable for bacteria to live there. The high salt concentration creates an isotonic environment that the bacteria cannot live in. Bacteria cells are unable to digest the salt, thus killing the cells by starvation.Cell growth and division occurin a regular cycle. This cycle is divided into four phases: G1, S, G2, and M.
