What is byte code?

We use Huffman’s algorithm to obtain an encoding of alphabet {a, b, c} with frequencies $f_{a}, f_{b}, f_{c}.$ In each of the following cases, either give an example of frequencies $\left(f_{a}, f_{b}, f_{c}\right)$ that would yield the specified code, or explain why the code cannot possibly be obtained (no matter what the frequencies are). (a) Code: {0, 10, 11} (b) Code: {0, 1, 00} (c) Code: {10, 01, 00}

A code for {a, b, c, d, e} is given by a: 00 b. 01 c: 101 d: x 10 e: yz 1,where $\mathrm{x}, \mathrm{y}, \mathrm{z} \in\{0,1\}.$ Determine x, y,and z so that the given code is a prefix code.

Assume the data is linear.

The number of volunteers from the Millennial generation (those born in 1982 or later) has increased from $6.1$ million in 2003 to $11.6$ million in 2010.

Estimate the number of volunteers from the Millennial generation in 2008 and in 2014.

If spontaneous generation does not occur and the principle of biogenesis is true, what scientific question remains?

Using a dark line for the original parental DNA and a wavy line for DNA synthesized from parental DNA, show what the population of DNA molecules would look like in the fourth generation. (Parental DNA is the first generation)

Explain why Francesco Redi’s experiment with flies did not completely disprove spontaneous generation.

If you mated two purple-flowered plants from the P generation, what ratio of traits would you expect to observe in the offspring? Explain. What might Mendel have concluded if he stopped his experiment after the $F_1$ generation?

Why did Mendel continue some of his experiments to the F2 or F3 generation?

Explain the cellular advantage for the codon 5'-AAG-3' to code lysine and the codon 5'-AGG-3' to code for arginine.

Suppose the number of females in the nth generation of the population of a certain species is given by $P_n$. Further assume that on the average, each female member of the $n-1$ st generation gives birth to $b$ female offspring and that in each generation, $d$ females can be expected to die, where $b$ and $d$ are positive constants.

a. Set up and solve a difference equation to find $P_n$ in terms of $b, d$, and the initial population of females $P_0=P(0)$.

b. Suppose $P_0=100, b=0.2$, and $d=15$. What will be the female population of the 10 th generation? What happens to the female population in the long run (as $n \rightarrow \infty$ )?

What will the following code display?

try:
    x = float('abc123')
    print 'The conversion is complete.'
except IOError:
   print 'This code caused an IOError.'
except ValueError: 
  print 'This code caused a ValueError." 
print 'The end.'

The United Group for Divisive Action uses secret code words that are permutations of 5 characters. You learn that there are only 10 code words. What can you say about repeated characters in the code words?
