Based on the information above, which structure was most likely directly affected by the mutation?

“A person’s blood pressure begins to drop after losing a moderate amount of blood. Specialized structures in blood vessels detect this change and send signals to the brain. The brain then sends signals that cause the heart to beat faster and blood vessels to narrow, helping blood pressure return toward normal. In this scenario, the heart and blood vessels changing their activity are functioning primarily as:”

A 70 kg student sits at rest on a chair. The system is in equilibrium. What is the magnitude and the direction of the force the chair exerts on the student? What is the magnitude and the direction of the force the student exerts on the chair? Explain which law(s) are used to justify your answers.

If the acceleration of an object is constant, can its velocity also be constant?  

A bicycle begins at rest and accelerates uniformly at 3 m/s² along a straight line. How far does it travel in 6 seconds?

An object starts from rest and begins moving with a constant nonzero acceleration along a straight line. Which statement best describes its velocity over time?

6.0-kg block is pushed northward with a force of 18.0 N while at the same time a force of 6.0 N is applied southward. Which statement best describes the motion of the block?  

A firefighter slides down a vertical pole at a constant speed. A friction force from the pole acts upward while gravity acts downward. Which statement best describes the relationship between the forces acting on the firefighter?

On the answer sheet provided to you for the exam, or scrap paper, complete all of the parts of the following question: Written Response Question 6 (8 pts): The following compounds do not undergo the reactions you would expect based on the substitution of the alkyl halide. In each case, briefly explain why the indicated reaction(s) will not work:         Click to Show Image Description A chemical structure with accompanying text. The compound is a rigid, bridged polycyclic molecule. At the base of the structure are two fused benzene rings, drawn as two six-membered rings sharing a bond, forming a planar aromatic framework. Above the fused benzene rings, a bridged bicyclic framework is present, consisting of additional carbon atoms that form a constrained ring system connecting across the top of the molecule. On one carbon of this upper bridged framework, a chlorine atom (Cl) is attached, shown with an explicit bond. Three hydrogen atoms are explicitly drawn and labeled (H, H, H) at specific positions on the bridged portion of the molecule, with their spatial positions indicated by the bond angles shown. To the right of the structure, the text reads “unreactive under E2 conditions.”       Click to Show Image Description A chemical structure with accompanying text. The compound is drawn in a three-dimensional perspective as a rigid, cage-like bridged bicyclic framework. The structure consists of two bridgehead carbons connected by multiple carbon bridges, creating a constrained polycyclic skeleton. An iodine atom (I) is attached at the lower bridgehead carbon of the cage structure, shown at the bottom left of the drawing. The three-dimensional perspective of the drawing conveys the rigid, locked nature of the bicyclic framework. To the right of the structure, the text reads “Unreactive by E2 or S꜁2.”

Written Response/Drawing Questions Instructions The next six questions are Written Response 1 through 6. These are separate from the Canvas question numbering because you will write or draw your answers by hand. Use the CHEM 210 Exam 3 Answer Sheet if you printed it or copied it onto your own paper before the exam. If not, use blank scrap paper. You may not print the answer sheet during the exam. Clearly number each handwritten answer so it matches the written response question. After you complete Written Response Question 6, continue with the rest of the Canvas exam, beginning with Question 2. Do not upload your handwritten work during the exam. You will submit it after you have fully completed the exam.
