In living things, energy is stored in the molecule adenosine triphosphate, called ATP for short. ATP is said to act like a battery, storing energy when it is not needed and instantly releasing energy when it is required. Investigate how energy is stored and the role of ATP in biological processes. Write a report including at least three references.

Suppose R is the region bounded by y=f(x) and y=g(x) on the interval [a, b], where f(x)

$$\geq g ( x ) \geq 0$$

. How is this formula changed if the line

$$y=y_0$$

lies above R?

Determine whether each statement makes sense or does not make sense, and explain your reasoning. Because I have two points to work with, I use the formula for slope

$$\frac { y _ { 2 } - y _ { 1 } } { x _ { 2 } - x _ { 1 } }$$

to find the slope of the tangent line to the graph of a function

$$y = f ( x ) \text { at } ( a , f ( a ) ).$$

Consider the following reactions: $\mathrm { H } _ { 2 } ( g ) + \mathrm { I } _ { 2 } ( g ) \rightleftharpoons 2 \mathrm { HI } ( g ) \quad \text { and } \quad \mathrm { H } _ { 2 } ( g ) + \mathrm { I } _ { 2 } ( s ) \rightleftharpoons 2 \mathrm { HI } ( g )$ List two property differences between these two reactions that relate to equilibrium.

A classical example of the Poisson distribution involves the number of deaths caused by horse kicks to men in the Prussian Army between 1875 and 1894. Data for 14 corps were combined for the 20-year period, and the 280 corps-years included a total of 196 deaths. After finding the mean number of deaths per corps-year, find the probability that a randomly selected corps-year has the fo llowing numbers of deaths: 0. The actual results consisted of these frequencies: 0 deaths (in 144 corps-years); l death (in 91 corps-years); 2 deaths (in 32 corps-years); 3 deaths (in 11 corps-years); 4 deaths (in 2 corps-years). Compare the actual results to those expected by using the Poisson probabilities. Does the Poisson distribution serve as a good tool for predicting the actual results?
