How did the Meselson & Stahl’s experiment allow the investigators to distinguish between the 3 overall methods of DNA replication? What approaches were used in investigating the enzymology of DNA replication, remembering that studying an essential function presents a particular challenge?

One of the substances (ethylene glycol) appeared to increase in temperature as it evaporated (Change in temperature upon complete evaporation: +1.4). How can this be the case? What alteration to the experiment could have been done to test and see if this evaporation could be exothermic or did that liquid even evaporate at all?

If the endpoint in a titration was reached using a volume of 37.60 mL and the concentration of the standard NaOH solution was 0.3214 M, how many grams of KHP were neutralized in this experiment? (MM of KHP = 204.23 g/mol)

Report your answer in grams but do not include units in your response.

[NAC (Nanoparticle Assembled Capsule)] The purple dye used to demonstrate encapsulation in this experiment is a mixture. The components of this colour are Carmoisine (Red) and Indigo Carmine (Blue). The yellow colour Curcumin could not be encapsulated when tried. Why?

Please be specific in terms of molecular structure and its chemical properties.

In a physics lab experiment, a compressed spring launches a 30 gmetal ball at a 25 ∘ angle. Compressing the spring 19 cm causes the ball to hit the floor 1.7 m below the point at which it leaves the spring after traveling 6.0 m horizontally.

What is the spring constant?

1. (3) How could you tell if a plant you have found is a sporophyte or a gametophyte? Use your imagination and describe an experiment you could do.

2. (3) a. Explain why the sporophyte is “dependent” on the gametophyte in the moss and the fern.

b. Which is the “dominant” form in each of these?

IN C++:

Create sets of 1 Million integer, where no integer is repeated. Insert these numbers to an AVL tree and an R-B tree.

Using a random number generator, select 10% of the numbers in the trees and delete them.
Repeat the experiment 10 times. Report your answers in a tables

A 6.210 gram sample of an organic compound containing C, H and O is analyzed by combustion analysis and 10.34 grams of CO2 and 3.388 grams of H2O are produced. In a separate experiment, the molar mass is found to be 132.1 g/mol. Determine the empirical formula and the molecular formula of the organic compound.

1. Alice is moving wit 0.8c towards a mirror. She sends a light pulse towards the mirror when she is at a distance L from the mirror. Bob is at rest with respect to the mirror and is observing this experiment. After how long will Alice receive the reflected pulse, as measured by Alice and Bob?
