Question

  1. what role does dna play in the cell?

a. provides a medium for organelles to function
b. controls the movement of substances in and out of the cell
c. produces energy for the cell
d. contains genetic instructions for cell development and functioning

  1. how do cells respond to a decrease in water concentration within them?

a. by releasing atp
b. by taking in more water or reducing salt concentration to restore balance
c. by stopping all metabolic processes
d. by increasing glucose production

  1. which organelle is primarily involved in the synthesis of proteins and lipids?

a. lysosomes
b. endoplasmic reticulum
c. nucleus
d. golgi apparatus

  1. what is the function of the rough endoplasmic reticulum?

a. controlling cell division
b. producing energy for the cell
c. storing dna
d. synthesizing proteins due to the presence of ribosomes.

  1. which phase of mitosis follows anaphase?

a. cytokinesis
b. telophase
c. metaphase
d. prophase

  1. what is the function of the cytoplasm in the cell?

a. it contains the entry and exit of substances in the cell
b. it houses the genetic material of the cell
c. it provides a medium for organelles to function and reactions to take - place
d. it produces energy through cellular respiration

  1. what happens to glucose during glycolysis?

a. it is stored in the mitochondria for later use
b. it combines with oxygen to produce energy
c. it is broken down into pyruvate and atp
d. it is converted into water and carbon dioxide

Explanation:

Brief Explanations
  1. DNA contains genetic information for cell - related processes, so the answer is based on this key property.
  2. Cells try to maintain osmotic balance when water concentration changes by taking in water or adjusting solute concentration.
  3. The endoplasmic reticulum is involved in protein and lipid synthesis.
  4. The rough endoplasmic reticulum has ribosomes and synthesizes proteins.
  5. Anaphase is a distinct phase in mitosis.
  6. Cytoplasm provides a medium for organelles to function.
  7. During glycolysis, glucose is broken down into pyruvate and ATP.

Answer:

  1. d. Contains genetic instructions for cell development and functioning
  2. b. By taking in more water or reducing solute concentration to restore balance
  3. b. Endoplasmic Reticulum
  4. d. Synthesizing proteins due to the presence of ribosomes
  5. None of the options provided are correct for "which phase of mitosis is anaphase?" (Anaphase is the stage where sister chromatids separate). If we assume the options are meant to be stages of mitosis and we pick the closest related one conceptually, it's not clear from these options. But if we consider the naming - convention and stages, it's not among these choices.
  6. c. It provides a medium for organelles to function and reactions to take place
  7. d. It is broken down into pyruvate and ATP
