What differences might you expect to see in the cell membranes of organisms that live in colder environmental conditions? 

You might expect to see the phospholipids in their cell membranes have longer fatty acid tails and more cis-double bonds to increase membrane fluidity and prevent gelling.

A student hopes to freshen up their soggy carrots by placing them in a bowl of distilled water. What mechanism is actually at play here, and what should happen to the carrots? 

Distilled water is a hypotonic environment to the carrot. Water will move into the carrot (which has a higher solute concentration), making it crunchier.

How might the uptake of nutrients in the gut epithelium be impacted if the sodium potassium pump were not present? 

In the gut epithelium, glucose must move AGAINST its concentration gradient via coupled secondary active transport with sodium. This sodium moves passively into the gut epithelium (where the Na concentration is lower) to maintain this low concentration, we must make use of the sodium potassium pump.

Checkpoints play a key role in ensuring proper cell division occurs. Describe the three checkpoints a cell must pass in order to successfully complete mitosis, naming the main mechanism of regulation at play. 

Three checkpoints include the restriction point (G1/S) the G2/M checkpoint, and the spindle checkpoint (in the M phase)

The use of a toxin causes a mutation in the g-proteins of an organism that interferes with their GTP-ase activity. What impact would this have on signalling within the organism? 

G proteins would remain active and continue to send signals unnecessarily throughout the cell. This might impact a pathway like the phospholipase pathway.

List all the forces acting on a tennis ball and the racquet during contact and what these forces are from (ie. where is the applied force from).

Ball: what is gravity, static OR kinetic friction, and the applied force from the racquet?

Racquet: What is gravity, the applied force from the person, and the applied force from the ball?

A steel ball with mass m is suspended from the ceiling at the bottom end of a light, 15.0 metre long rope. The ball swings back and forth like a pendulum. When the ball is at its lowest point and the rope is vertical, the tension in the rope is three times the weight of the ball, so T=3mg

What is the speed of the ball as it swings through this point?

What is 17.1 m/s?

What is a correct expanded formula for the conservation of  momentum during a collision between a bullet and the edge of a rotating solid disk? Define your variables. Assume the velocity of the bullet encourages rotation of the disk (ie. the tangential velocity of the bullet is in the same direction as the tangential velocity of the disk where it strikes)

What is mbRvbi + Idωi = (Ib+Id)ωf
