Problem: Bacteria, as asexual organisms, inherit identical copies of their parent's genes (i.e., they are clonal). However, all bacteria can evolve by selection on changes to their genetic material DNA caused by genetic recombination or mutations. Mutations come from errors made during the replication of DNA or from exposure to mutagens. Mutation rates vary widely among different species of bacteria and even among different clones of a single species of bacteria. Genetic changes in bacterial genomes come from either random mutation during replication or "stress-directed mutation", where genes involved in a particular growth-limiting process have an increased mutation rate.
What makes bacteria an asexual organism?
The answer is the following: inherit identical copies of their parent's genes

where the uncertainty is given as the standard deviation of the measured value from its expected value. There are a number of other such pairs of physically measurable values which obey a similar rule. One example is time vs. energy. The either-or nature of uncertainty forces measurement attempts to choose between trade offs, and given that they are quanta, the trade offs often take the form of either-or (as in Fourier analysis), rather than the compromises and gray areas of time series analysis.
What example is given as another paired relationship of uncertainly related to standard deviation?
time vs. energy

Input: Portugal
Portuguese cinema has a long tradition, reaching back to the birth of the medium in the late 19th century. Portuguese film directors such as Arthur Duarte, Antonio Lopes Ribeiro, Antonio Reis, Pedro Costa, Manoel de Oliveira, Joao Cesar Monteiro, Antonio-Pedro Vasconcelos, Fernando Lopes, Joao Botelho and Leonel Vieira, are among those that gained notability. Noted Portuguese film actors include Joaquim de Almeida, Daniela Ruah, Maria de Medeiros, Diogo Infante, Soraia Chaves, Ribeirinho, Lucia Moniz, and Diogo Morgado.

Who are some examples of Portuguese film directors?
Output: Arthur Duarte, Antonio Lopes Ribeiro, Antonio Reis, Pedro Costa, Manoel de Oliveira, Joao Cesar Monteiro, Antonio-Pedro Vasconcelos, Fernando Lopes

Input: Article: The Sun has been openly antagonistic towards other European nations, particularly the French and Germans. During the 1980s and 1990s, the nationalities were routinely described in copy and headlines as "frogs", "krauts" or "hun". As the paper is opposed to the EU it has referred to foreign leaders who it deemed hostile to the UK in unflattering terms. Former President Jacques Chirac of France, for instance, was branded "le Worm". An unflattering picture of German chancellor Angela Merkel, taken from the rear, bore the headline "I'm Big in the Bumdestag" (17 April 2006).

Now answer this question: What names were used by The Sun to characterize the French and Germans?

Output: "frogs", "krauts" or "hun"

Article: In a channel transupport system, several proteins form a contiguous channel traversing the inner and outer membranes of the bacteria. It is a simple system, which consists of only three protein subunits: the ABC protein, membrane fusion protein (MFP), and outer membrane protein (OMP)[specify]. This secretion system transports various molecules, from ions, drugs, to proteins of various sizes (20 - 900 kDa). The molecules secreted vary in size from the small Escherichia coli peptide colicin V, (10 kDa) to the Pseudomonas fluorescens cell adhesion protein LapA of 900 kDa.

Question: What three protien subunites are in the chennel transupport system?
Ans: the ABC protein, membrane fusion protein (MFP), and outer membrane protein (OMP)[specify]

Input: Electric motor
Stepper motors are a type of motor frequently used when precise rotations are required. In a stepper motor an internal rotor containing PMs or a magnetically soft rotor with salient poles is controlled by a set of external magnets that are switched electronically. A stepper motor may also be thought of as a cross between a DC electric motor and a rotary solenoid. As each coil is energized in turn, the rotor aligns itself with the magnetic field produced by the energized field winding. Unlike a synchronous motor, in its application, the stepper motor may not rotate continuously; instead, it "steps"starts and then quickly stops againfrom one position to the next as field windings are energized and de-energized in sequence. Depending on the sequence, the rotor may turn forwards or backwards, and it may change direction, stop, speed up or slow down arbitrarily at any time.

When are stepper motors most useful?
Output:
when precise rotations are required
