Ms. Boll has been driving in circles around the SMLS parking lot for the past 30 mins, looking for a parking spot, but the Grade 12s have taken up all of the spots! To pass the time, she turns on some Taylor Swift songs and decides to calculate the angle between her car’s velocity and the radius of the parking lot. For an object traveling in circular motion, its own velocity (at any point) and the radius of the circle always make an angle of:
A) 0°
B) 90°
C) 120°
D) 180°
B) 90°

Mr. Brims decides that he wants to start growing a plant for his office. He finds out that the specific colour of plant that he wants (hot pink) is a reccessive trait. Which of the following statements accurately describes the inheritance pattern of a recessive allele in a population?
A) A recessive allele will always be expressed in the phenotype when present, even if only one copy is inherited
B) An individual with a heterozygous genotype for a recessive allele will express the recessive phenotype if the allele is present
C) A recessive allele can be expressed in the phenotype only if the individual is homozygous for the recessive allele
D) Recessive alleles are always more common in a population than dominant alleles
C) A recessive allele can be expressed in the phenotype only if the individual is homozygous for the recessive allele

Mr. Read wants to make sure that no one is distracted in class, so he sends a satellite to space that can detect when a student takes their phone our of their backpack. He’s happy to see that no students ever breaks the rules and takes out their phone! (his satellite may just be broken though...) The period of a satellite is independent of:
A) It's own mass
B) The mass of the planet it orbits
C) The value of the gravitational constant
D) The orbital radius
A) It's own mass

5. Mr. Fillion walks into Ms. Reynold’s class while they are examining DNA. He accidentally treats a piece of DNA with a mutagen, and has to find out what happened to the DNA before Ms. Reynolds comes back!
Examine the following sequence of DNA before and after treatment with a mutagen. Identify the type of mutation and describe the effect, if any, on the amino acid sequence.
wmRNA:
3’GCCAAAUCGAGCAAA 5’
mmRNA: 3’ GCCAAUCGAGCAAA 5’
A) Type: Base - Pair Substitution. Effect: Silent mutation as the amino acid sequence does not change
B) Type: Base Pair Substitution x2. Effect: Missense as the initial B-P sub changes the amino acid sequence.
C) Type: Deletion. Effect: due to the deletion of ‘A’ the codons have shifted changing and shortening the amino acid sequence.
d)Type: Insertion + Deletion. Effect: Frameshift shortening the amino acid sequence
C) Type: Deletion. ffect: due to the deletion of ‘A’ the codons have shifted changing and shortening the amino acid sequence.

Ms. Singhal wants to make sure that the students in the school aren’t feeling too much pressure. To fully understand what pressure feels like, she decides to set up a chemical reaction which she will add pressure to!
Consider the following reaction at equilibrium:
Which of the following statements best describes the effect of increasing the pressure on the system at equilibrium?
A) The reaction will shift to the right to produce more ammonia because there are fewer moles of gas on the right side of the equation
B) The reaction will shift to the left to produce more nitrogen and hydrogen because there are more moles of gas on the left side of the equation
C) The reaction will shift to the left because the increase in pressure will break the bonds in NH₃, favoring the decomposition of ammonia
D) The reaction will not be affected by the increase in pressure, since the number of gas molecules on both sides is the same
A) The reaction will shift to the right to produce more ammonia because there are fewer moles of gas on the right side of the equation

A) The impossibility of faster-than-light travel
B) The relationship between energy and mass
C) The simultaneous measurement of position and momentum
D) The wave-particle duality of photons
C) The simultaneous measurement of position and momentum
