Answer:
The study of extremophiles provides an understanding of the physicochemical parameters defining life on Earth and may provide insight into how life on Earth originated. The postulations that extreme environmental conditions existed on primitive Earth and that life arose in hot environments have led to the theory.NASA is studying an extremophile, Deinococcus radiodurans, which is extremely resistant to radiation. This microbe can withstand doses of radiation 500 percent higher than would be lethal to humans.

Explanation:
Which of the following devices are used in networking?A. Routers.
B. Hubs.
C. TCP.
D. Switches.
Answer:
A, Routers
Explanation:
Routers are used
The devices used in networking are:
A. Routers
D. Switches
Thus, option (A) and (D) are correct.
A. Routers: Routers are network devices that facilitate the transfer of data packets between different networks. They determine the best path for data to reach its destination and enable communication between devices on separate networks.
B. Hubs: Hubs were commonly used in early networking but are now outdated. They are passive devices that broadcast data to all connected devices, leading to inefficient data transmission.
C. TCP: TCP (Transmission Control Protocol) is not a networking device but rather a communication protocol used in the transport layer of the TCP/IP protocol suite. It ensures reliable data delivery by establishing a connection between devices and managing data flow control.
D. Switches: Switches are network devices that connect multiple devices within a local area network (LAN). They forward data packets only to the intended recipient, allowing for efficient data transmission within the same network.
Thus, Routers and Switches are parts.
Thus, option (A) and (D) are correct.

Answer:
Replace ______ with except
Explanation:
Your program is an illustration to try except in Python
When the Python interpreter sees a try statement, it expects a corresponding an except statement
So, the complete program is:
class TooWide(Exception): pass
answer = input('How wide is it? ')
width = float(answer)
try:
if width > 30:
raise TooWide
else:
print("Have a nice trip!")

You resurrected an old worksheet. It appears to contain most of the information that you need, but not all of it. Which step should you take next?
a) Check for data you have previously hidden.
b) Make the columns wider.
c) Check that the worksheet is not Read-Only.
d) Change the format to reduce the font size.
Answer:
a)
Explanation:
Since the worksheet contains most of the data that you need, there is a decent possibility that it also contains the data that you are missing. Therefore, you should check for data you have previously hidden. Sometimes, some data in a worksheet may become irrelevant in a given moment, and instead of deleting it since it may be useful later most people tend to make that data hidden. So checking for previously hidden data may be the best solution in this scenario.

Which of the following is not a property of a constructor?A. The name of a constructor can be chosen by the programmerB. A constructor is called using the new operatorC. A constructor must have the same name as the classD. Constructors may be overloaded
Answer:
The answer is "Option A"
Explanation:
The constructor is a special member function whose task is to initialize an object from its class, and it doesn't return any value like int, float, double, etc. Its name and class name will always be the same, and when we create the class object so, the constructor is automatically called, and it may be overloaded, that's why we can say that except the "choice A", all were correct.

Which of the following conditions would most likely result in corrupted data? A. an open in a cable B. a VLAN mismatch C. a short in a cable D. none of above
Answer:
D. none of above
Explanation:
Option A is not appropriate because an open in a cable does not the data to be transferred at all. An open in the cable is when the intended connection is missing or there is a break in the wire which stops the current flow.
Option B is also incorrect because a VLAN mismatch is causes when two connected switch ports have different VLAN configurations and this does not let the data propagate successfully. So connectivity issues occur between the devices and data cannot be exchanged between them.
Option C is also incorrect because a short in a cable, like an open in a cable, does not let the data to be transferred. A short in a cable is when an unintended connection is there such as when two wires touch each other. So this leads to the current flow through the short.
The possible condition that can cause corrupted data are:
bad cables: using a wrong category of cables in order to interconnect devices for exchanging data.
exceeded cable distance limit: When the cable distances are exceeded this might result in signal loss.
faulty connectors: these are broken connectors which do not properly make a connection.

what is a good rule-of-thumb for using color background in a worksheet?
Answer: The answer is given below
Explanation:
A good rule-of-thumb for using color background in a worksheet are:
• Avoid using more than four colors as ideally 2-3 colors should be used.
• Opt for tones, shades, and tints rather than being tempted to use many colors.
• Colors that are controversial should be avoided.
• Color should be added when it's required to pass across a message.
• A base color should first be selected, then complementary colors should be added to it.
What is an artificial intelligence system that mimics the evolutionary, survival-of-the-fittest process to generate increasingly better solutions to a problem?A. Intelligence system.B. Artificial intelligence.C. Neural network.D. Genetic algorithm.
Artificial intelligence system exploits the use of computers and technological devices to simulate the human mind's to solve potential problem concerns and make strategic decisions.
Artificial intelligence is essential due to the fact that it provides businesses with virtually unlimited insights into their operations and in some circumstances, Artificial intelligence can carry out tasks better than people, especially when it comes to recurring, technical-detailed activities like reviewing huge quantities of datasets to ensure essential fields are accurately filled in.
However, Neural networks are based on Deep learning techniques, which are a subfield of machine learning. They're designed by the use of the concept of the human brain, and they work by simulating how real neurons communicate with one another.
In the disciplines of Artificial intelligence and machine learning, neural networks mimic the activity of the human brain, enabling computer programs to identify patterns, formulate strategies and tackle basic problems.
Finally, from the scope of Artificial intelligence, Genetic algorithm emulates the principle of Darwinian selection which chooses only the fittest for reproduction. By replicating the evolutionary path of survival-of-the-fittest to accomplish a stated goal, genetic algorithms could solve difficult issues with numerous variables and a huge number of alternative solutions.
Therefore, from the above explanations, we can conclude that an artificial intelligence system that mimics the evolutionary, survival-of-the-fittest process to generate increasingly better solutions to a problem is known as a Genetic algorithm.
