What is the difference between biogenesis and spontaneous generation?

Studies done by Harry and Margaret Harlow found that a. nutrition was the most important factor in attachment. b. contact comfort was the most important factor in attachment. c. the surrogate mother's appearance was the most important attachment factor. d. monkeys were equally likely to become attached to either surrogate mother. e. the monkeys didn't form attachments to the surrogate mothers.

What did Harlow's research on rhesus monkeys reveal?

Describe the natural process that must be arrested in order for fossilization to take place.

The following table, based on data reported in the literature [HEAT84], shows the execution times, in seconds, for five different benchmark programs on three machines.

$$\begin{array}{|c|r|r|r|} \hline {}{\text { Benchmark }} & {\text { Processor }} \\ & \mathbf{R} & \mathbf{M} &{\mathbf{Z}} \\ \hline \mathbf{E} & 417 & 244 & 134 \\ \hline \mathbf{F} & 83 & 70 & 70 \\ \hline \mathbf{H} & 66 & 153 & 135 \\ \hline \mathbf{I} & 39,449 & 35,527 & 66,000 \\ \hline \mathbf{K} & 772 & 368 & 369 \\ \hline \end{array}$$

a. Compute the speed metric for each processor for each benchmark, normalized to machine R. That is, the ratio values for R are all 1.0. Other ratios are calculated using Equation (2.5) with R treated as the reference system. Then compute the arithmetic mean value for each system using Equation (2.3). This is the approach taken in [HEAT84].

b. Repeat part (a) using M as the reference machine. This calculation was not tried in [HEAT84].

c. Which machine is the slowest based on each of the preceding two calculations?

d. Repeat the calculations of parts (a) and (b) using the geometric mean, defined in Equation (2.6). Which machine is the slowest based on the two calculations?

When is meta-analysis is most useful?

Construct a JK flip-flop using a D flip-flop, a two-to-one-line multiplexer, and an inverter.

The life, in years, of a certain type of electrical switch has an exponential distribution with an average life \beta=2. If 100 of these switches are installed in different systems, what is the probability that at most 30 fail during the first year?
