Bio-Technology QUESTION #10581

Question 325

The specific oxygen uptake rate (OUR) in a fermentation is best described as:

$OUR = k_La \cdot (C^* - C_L)$
$OUR = q_{O_2} \cdot x$✔️
$OUR = \mu \cdot Y_{X/O_2}$
$OUR = D \cdot (C_{in} - C_{out})$

Correct Answer Logic:

The volumetric oxygen uptake rate (OUR, mmol O₂ L⁻¹ h⁻¹) is: $OUR = q_{O_2} \cdot x$, where $q_{O_2}$ is the specific oxygen consumption rate (mmol O₂ g⁻¹ biomass h⁻¹) and $x$ is biomass concentration. At steady state, OUR must equal the oxygen transfer rate (OTR): $OTR = k_La(C^* - C_L)$, where $k_La$ is the volumetric mass transfer coefficient and $C^*$ is the dissolved oxygen saturation concentration.

Education QUESTION #6757

Question 328

A teacher preparing a summative end-of-unit test for a chapter on climate change that received 150 minutes of instructional time out of 500 total minutes for the unit wants to allocate marks proportionally using a Table of Specification. If the total test is worth 50 marks, how many marks should be allocated to climate change content?

7
10
15✔️
25

Correct Answer Logic:

Using the Table of Specification formula: Percentage of instruction time = (150/500) × 100 = 30%. Mark allocation = 30% of 50 = 15 marks. The Table of Specification ensures that the proportion of test marks mirrors the proportion of instructional time devoted to each content area.

Journalism / Mass Communication QUESTION #6417

Question 329

The first wide-coverage telex network was implemented in which country and for what primary purpose?

United States, for commercial business communication in 1945
Germany, in the 1930s, used primarily for government communication — allowing up to 25 telex channels to share a single long-distance telephone line at 45.5 bits per second✔️
Britain, in the 1920s, for military communication during World War I
Japan, in the 1950s, for international business communication

Correct Answer Logic:

The telex system represented an important intermediate stage between the telegraph and modern digital data communication. According to the textbook:

Telex machines first appeared as an evolution of telegraph technology, using telephone-like rotary dialing to connect teleprinters (teletypes)
By 1935, message routing was the last barrier to full automation of the system
The first wide-coverage telex network was implemented in Germany in the 1930s, used primarily for government communication
Technical specifications: 45.5 bits per second; up to 25 telex channels could share a single long-distance telephone channel
This made telex the least expensive method of reliable long-distance communication at the time

Telex eventually became a global business standard for transmitting documents internationally, particularly important for news agencies (like Reuters) and international trade, before being superseded by fax and then email in the late 20th century.

Chemistry QUESTION #5577

Question 334

Which of the following compounds gives a positive silver mirror test (Tollens' test)?

Acetone
Formaldehyde
Benzophenone
Acetaldehyde✔️

Correct Answer Logic:

Tollens' test (silver mirror test) is positive for aldehydes, which are oxidized to carboxylate ions while $Ag^+$ is reduced to metallic silver. Acetaldehyde ($CH_3CHO$) is an aldehyde → positive. Acetone and benzophenone are ketones (do not respond to Tollens'). Formaldehyde also gives a positive test, but acetaldehyde is listed here as the textbook answer.

Correct Answer Logic:

A primary reinforcer directly satisfies a biological need without prior learning. Food is the classic example, satisfying the hunger drive immediately. Money, pay checks, and clothes are secondary (conditioned) reinforcers.
