(a).        A 92 kg high jumper running 11 m/s executes a jump. (i).       What is his kinetic energy before the jump?                                                                                      (1.5 points)  (ii).     Using the law of conservation of energy or otherwise, calculate how high he can jump.                    (1.5 points) (b).        A 15 kg mass hangs on a spring causing it to stretch by 0.22 m. (i).         Calculate the spring constant.                                                                                                             (1.5 points) (ii).       Calculate the work done in stretching the spring by 0.22 m.                                                              (1.5 points)

Which of the following molecules is most easily able to diffuse across the cell membrane?

A competitive inhibitor interferes with the _________ site of the enzyme so a substrate cannot bind.

Which of the following is found in all prokaryotic cells, but not found in all eukaryotic cells?

Which of the following statements about transport through the plasma membrane of a cell is correct?

DNA, thylakoids, and stroma are components of which eukaryotic organelle?

How is the majority of ATP produced in cells?

For each statement below, determine whether each condition will promote microtubule polymerization or depolymerization. The addition of a drug that prevents GDP-tubulin from dissociating from the polymer will promote microtubule [1]. The addition of a drug that inhibits GTP hydrolysis in subunits incorporated into the polymer will promote microtubule [2]. The addition of a drug that caps the minus end of the microtubule and prevents subunit exchange at the minus end will promote microtubule [3]. The addition of a drug that promotes GTP hydrolysis in the microtubule will promote microtubule [4].

Which of these animals does the speaker of “Ego Tripping (there may be a reason why)” by Nikki Giovanni compare herself?
