You want to create a function in Excel to allow you to quickly calculate the speed of a sound wave.  The formula used to calculate this is as follows: Speed = Distance / Time In the space provided below, type the lines of code that are needed to define variables for this user-defined function.  Do not type anything else (don’t type the entire macro).  Assume the values used in this formula will be whole numbers.  (5 points)     

Visual Basic for Applications is a programming language used to create macros.  This programming language is a descendant of what programming language:

Which Do Loop syntax form should be used if you want the loop to continue during the time the condition is true, and you want the condition to be tested after the statements of code are run?

Chromatin structure can vary along the length of the chromosome. The diagram below illustrates two general structural types (I and II) that result from histone modification. Based on the illustration, answer each question below. Question Type_I Type_II Name each chromatin type What histone post-translational modification leads to its formation? In general, are genes expressed in this region of the chromosome? (yes or no)

Briefly describe why using a mouse is a more effective model organism than an elephant when trying to investigate conserved biological processes.

For each polymerase listed in the table below, select the RNA type it generates and the corresponding the function of its product. Enzyme RNA_type Function RNA pol I RNA pol II RNA pol III

What did the Hershy-Chase experiment demonstrate?

The diagram to the below illustrates a eukaryotic interphase chromosome where three essential DNA sequence elements are marked (1-3). Name each corresponding DNA element and briey describe the major function in the table below. region name function 1 2 3

Match each enzyme with the most appropriate description.

For each of the following statements relating to allostery, indicate if the statement is TRUE or FALSE.Allosteric regulators are often products of other chemical reactions in the same biochemical pathway. Allosteric regulation is always used for negative regulation of enzyme activity. Binding of allosteric molecules usually locks an enzyme in its current conformation, such that the enzyme cannot adopt a different conformation.
