As you know, biochemistry is essential for the process of life and can be found in all living cells, from microbe to human. Please list the four classes (families) of biomolecules. For each biomolecule (AKA Macromolecule), list its building block (monomer) and the type of chemical bond formed. Lastly, provide the major functions of each biomolecule in a typical living cell.

Robert Koch helped establish the germ theory of disease by discovering that anthrax was caused by a disease. After he isolated and purified the same bacteria from several diseased animals, what would be the next step in order to show that this bacteria caused anthrax?

Imagine that you are a research scientist and have recently discovered a method to engineer a bacteria from simple biomolecules that will change science forever. You are well on your way to receiving the Nobel Prize but you first must prove that it works. You want to design a pathogenic bacteria but are deciding whether to design it as a Gram-positive or Gram-negative bacteria. Which one would decide to make? Why? Fully justify your answer with what you have studied about Gram-positive versus Gram-negative bacteria.

What happens when you place a bacterial cell into a hypertonic solution?

A team of six people work to lift a platform of cargo with a mass of 300 kg up a cliff with a single rope and pulley. If the cargo rises with a constant speed of 0.75 m/s, how much power must each person provide?

List and describe the steps of the evolution of eukaryotic cells on Earth, known as the endosymbiotic theory.

Which of the biomolecules is incorrectly matched with its building block?

A cylindrical container with a 40-cm height and a 2.0-cm diameter contains helium gas, which has density 0.1785 kg/m3. A piston on one side of the container moves inwards until the helium’s density is 0.22 kg/m3. What is the new height of the cylinder?

Marie and Maria each send a spinning uniform disc towards the center of an axle. Marie’s disk has a mass of 0.5 kg with a radius of 15 cm and is spinning about the axle at a rate of 120 rpm. Maria’s disk also has a mass of 0.5 kg, but a radius of 20 cm, and it spins in the same direction as Marie’s at a rate of 150 rpm. The two discs then collide and stick together. What is their final rotational speed in rad/s?

A group of local troublemakers send a 600 kg cart crashing into an innocent cabbage stand at a speed of 16 m/s. If the average force on the wagon during the collision is 9500 N, how long does it take for the cart to stop?
