4(B) Which statement best explains the function of the vesicles?

• Delivering packaged materials to the Golgi apparatus for protein synthesis

• Exchanging genetic information between the Golgi apparatuses of separate cells

• Extracting portions of the Golgi apparatus to be regenerated for growth within the cell

• Transporting packaged molecules from the Golgi apparatus to be released out of the cell

In the 1880s, Louis Pasteur developed a method of weakening viruses. The weakened viruses could be injected into healthy individuals. How is this method effective in fighting viral diseases?

• The immune system develops antibodies in response to the weakened viruses.

• The weakened viruses attach to unaffected viruses in the host and interrupt the viral reproductive cycle.

• The rate of genetic mutation in the host is decreased due to the introduction of weakened viruses.

• Weakened viruses are unable to enter the host organism.

5(A) The activities in the cell cycle occur during specific phases. In which phase of the cell cycle is DNA replicated?

• Mitosis

• G1 Phase

• G2 Phase

• S Phase

5(B)Which of the components could be observed using a microscope in a prepared slide of leaf epidermal cells but not in a prepared slide of human cheek cells?

• Components 2 and 3 only

• Components 3 and 4 only

• Components 1, 2, and 3 only

• Components 1, 5 only

4 (B) When mammals get an infection, their internal body temperature often rises 2 to 3 degrees Celsius. The body gets the energy it needs to react to an infection by —

• increasing the rate of cellular division

• decreasing the rate of glucose movement into the cell

• increasing the rate of cellular respiration in mitochondria

• decreasing the rate at which carbon dioxide is removed from the cell

• Arrow 1 represents mitosis, and Arrow 2 represents meiosis.

• Arrow 1 represents interphase, and Arrow 2 represents mitosis.

• Arrow 1 represents meiosis, and Arrow 2 represents prophase.

4(C) Which of these describes a difference between viruses and cells?

• Cells contain protein, and viruses contain only carbohydrates.

• Viruses have flagella, and cells have only cilia.

• Cells reproduce independently, and viruses require a host to reproduce.

• Viruses have membranes made of proteins, and cells have membranes made of nucleic acid.

5 (C) What is the role of mRNA in expressing specialized structures?

• Making energy available for cellular activities.

• Creating bonds to form biomolecules.

• Producing sugars that assist with replication.

• Providing information to form proteins.
