Answer:

The Hela cells live beyond the Hayflick limit due to the secretion of telomerase in the Hela cells.

Explanation:

Hayflick limit is the number of times a cell divides by mitosis, due to  the continuous shortening of the telomeres at the end of the chromosomes. It only apply to normal living cells.

Hela cells are human cancerous cells found in the cervix or the entrance of the uterus. They cause cervical cancer as they grow uncontrollably, affecting other cells around it.

The Hela cell survive the hayflick limit because it produces a hormone called telomerase, that continuously elongates the telomeres of the chromosomes, for continuous cell division.

Which of the following is NOT a factor that increases the health risks of construction workers?
Nadya [2.5K]

From all the available options, the one that would not increase the health risk for construction workers would be (D) stable, rarely changing job site environments and conditions.

High number of unskilled labors increase the likelihood that an accident might occur, while high turnover creates instability which in turn might increase the same likelihood due to increased workload while human resources seek a replacement. Multiple contractors and subcontractors mean confusions might arise and accident may likely happen if the risk is not properly managed.

Write a statement that defines an ifstream object named inputFile and opens a file named "Friends.txt".
Simora [160]

Answer:

ifstream inputFile;

inputFile.open("Friends.txt");

Explanation:

Though, the programming language is not stated, questions like this are often from C++.

The first statement defines the ifstream object using the following syntax.

ifstream [object_name]

In this case, the object name is inputFile

So, the syntax becomes

ifstream inputFile;

The next line opens a file using the following syntax.

[object_name].open("Filename")

Here, object_name is inputFile and filename is Friends.txt

So, the open statement becomes

inputFile.open("Friends.txt")

Given a effective delay of 99ms when network usage is 74%, what is the effective delay when network usage = 84% ?
NARA [144]

148.5 ms is the effective delay when network usage = 84% .

<h3>what is a computer network?</h3>
  • A group of computers sharing resources that are available on or offered by network nodes is known as a computer network.
  • Over digital links, the computers communicate with one another using standard communication protocols.
  • These connections are made up of telecommunication network technologies, which are based on physically wired, optical, and wireless radio-frequency means and may be set up in a number of different network topologies.
  • Personal computers, servers, networking equipment, and other specialized or general-purpose hosts can all function as nodes in a computer network.
  • They can have hostnames and are identifiable by network addresses.
  • After being assigned, hostnames act as recognizable labels for the nodes and are seldom updated.
  • Network addresses are used by communication protocols like the Internet Protocol to locate and identify the nodes.

Using language c, find the nth Fibonacci, knowing that nth Fibonacci is calculated by the following formula: - If n = 1 Or n = 2
Nina [5.8K]

Answer:

#include <stdio.h>

int fib(int n) {

 if (n <= 0) {

   return 0;

 }

 if (n <= 2) {

   return 1;

 }

 return fib(n-1) + fib(n-2);

}

int main(void) {

 for(int nr=0; nr<=20; nr++)

   printf("Fibonacci %d is %d\n", nr, fib(nr) );

 return 0;

}

Explanation:

The code is a literal translation of the definition using a recursive function.

The recursive function is not per se a very efficient one.
