Answer:

import java.util.Scanner;

public class ANot {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Please enter a string of words");

String n = in.nextLine();

int count = 0;

for (int i=0; i<n.length(); i++){

if((n.charAt(i) != '.') &&(n.charAt(i) != ',') && (n.charAt(i) != ' ')){

count++;

}

System.out.println(count);

}

}

Explanation:

Prompt User to input the string and assign to a variable
SET count =0.
Using a for loop iterate over the string
if((n.charAt(i) != '.') &&(n.charAt(i) != ',') && (n.charAt(i) != ' ')) then count =count +1.
PRINT count.

Answer:

user_text = input()

import re

str1= input("21 ")

pattern = '[a-zA-Z]'

count=0

i=0

while(i<=len(str1)-1):

result = re.match(pattern, str1)

if (result):

count+=1

else:

continue

i+=1

print("String Length:",count)

6. The NADH and FADH2 produced during the Krebs cycle pass their electrons down the 7. __ __ __ __ __ __ __ __ __ __ __ __ __ __

AlladinOne [14]

Answer:

The NADH and FADH2 produced during the Krebs cycle pass the electrons down electron transport chain in the mitochondria to generate more ATP molecules

Explanation:

FADH2 stands for Flavin adenine dinucleotide and NADH stands for Nicotinamide adenine dinucleotide.

Both are created from FAD and NAD+ through reduction-oxidation reactions in the Krebs cycle during respiration as explained below:

This cycle gives off small amounts of energy in the form of adenosine triphosphate, or ATP, and produces these compounds, FADH2 and NADH. The Krebs cycle is like a wheel. Every time it makes one full rotation, energy is created and released. As you can see from the diagram, the NAD+ and FAD are brought in at key points throughout the cycle and are attached to other electrons resulting in the formation of NADH and FADH2.

This energy is then shuttled off to be used by the cell, mostly for the continuation of cellular respiration.

As they are shuttled away, these two compounds are used to move electrons into the electron transport chain, the final stage of respiration. It is in this stage that most of the energy is created and released from the mitochondria (powerhouse of the cell).

Basically the NADH and FADH2 are affixed with electrons and tranfered to the inner membrane of the mitochondria. The travel down the electron transfer chain, releasing electrons they once had. Thereby releasing alot of energy in the process

The overall cost of wiring in addressable fire alarm system is significantly cheaper than the conventional one. Why is it so?

stellarik [79]

Answer:

Yes, The overall cost of wiring in addressable fire alarm system is significantly cheaper than the conventional one.But the addressale fire alram system is more reliable than a conventional system.

Explanation:

Conventional systems are hardware-based and use analog technology. where addressable fire alarm use digital technology. addressable system is generally more reliable than a conventional system mainly due to how the different systems are wired. With a conventional system, if a device’s wire is damaged or severed, its signal and the signal of other devices down the line cannot be transmitted to the control panel.

With an addressable system, both ends of the wire connect to the control panel. Therefore, if one end becomes damaged or severed, signals can still reach the control panel through the other end of the loop. In addressable systems, a device can be removed or disabled and it will not affect the other devices in the loop.

What should you do with a wireless-capable laptop if you connect a lan cable to it?

marusya05 [52]

A local-area network (LAN) cable is used in LAN networks to connect several computers or other networking devices.
If you connect a LAN cable to a wireless-capable laptop you should turn the wireless capability off to maximize security, because through the LAN cable viruses can be transmitted, than can harm your computer.
