Answer:B.Archean

Explanatiion : Beginning of the the Archean Eon, was a major time of ocean formation and availability of water molecules which were bonded to hydrogen atoms.

There was a lack of oxygen in the atmosphere eventhough it existed in water molecules. The available organisms were cyanobacteria which were blue- green algae. Eventhough oxygen wasn't there cyanobacteria were able convert sunlight to energy. This is when the photosynthesis took place , when they made their own food in the ocean and they secreted oxygen .

java Two smallest numbers Write a program that reads a list of integers, and outputs the two smallest integers in the list, in a
SashulF [63]

Answer:

The code to this question can be defined as follows:

import java.util.*;//import package for user input

public class Main //defining a class

{

public static void main(String[] args)//defining main method  

{

   int m1,m2,num,t,i;//defining integer variable

   Scanner incx = new Scanner(System.in);//creating Scanner class object

   m1 = incx.nextInt();//input value

   m2 = incx.nextInt();//input value  

   if (m1 > m2)//use if block to check m1 greater than m2  

   {//swapping value

       t = m1;//holding m1 value in t

       m1 = m2;//defining m1 that take m2

       m2 = t;//holding m2 value  

   }

   for (i = 2; i < 6; i++)//defining for loop  

   {

       num = incx.nextInt();//input value  

       if (num < m1) //defining if block to smallest value

       {

           m2 = m1;//holding m2 value in m1

           m1 = num;//holding num value in m1

       }  

       else if (num < m2)//defining if block to smallest value  

       {

           m2 = num;//holding num value in m2

       }

   }

       System.out.println(m1 + " " + m2);//print two smallest values

   }

}

Output:

5

10

5

3

21

2

2 3

Explanation:

In the above code, five integer variable "m1, m2, num, t, and i" is declared, in which it creates the scanner class object for inputs the value and use m1 and m2 use to the input value.

In the next step, if a block is used to swap the value and pass into the for loop that use if block to find the two smallest values and hold its value into the m1 and m2 and print its value.

How does a cloud-first strategy differ from other approaches to cloud?
Irina18 [472]

Cloud-first strategy differ from other approaches as It keeps all the services performed by legacy systems while moving to the Cloud in a staggered approach.

<h3>What is a cloud first strategy?</h3>

The change of cloud computing has brought about  “cloud-first” strategy.

This  is known to be a way to computing that tells that a firm should look first to cloud solutions when creating new processes or taking in old processes before taking in non-cloud-based solutions.

Note that Cloud-first strategy differ from other approaches as It keeps all the services performed by legacy systems while moving to the Cloud in a staggered approach.

See options below

it enables an organization to completely move to the cloud without infrastructure or support requirement

it keeps all the services performed by legacy systems while moving to the cloud in a staggered approach.

it partners technology with multiple other disciplines for comprehensive business transformation.

it uses artificial intelligence to automate all business processes and completely eliminate human error.

Computers process information consistently for all transactions. This creates a risk that:______
Anna007 [38]

Answer:

b. erroneous processing can result in the accumulation of a great number of misstatements in a short period of time.

Explanation:

Because of the consistent nature of processing in computers, this is capable of creating certain kinds of risk. From the option, one of the probable risk that can result from consistent information processing for multiple transactions at the same time is erroneous processing. This can therefore lead to a pile of misstatements in only a short period of time.

Consider the following statements regarding computer programs A - Variables can contain different values at different times.B -
jeka94

Answer:

The answer is: Only A is correct.

Explanation:

Variables in a program can assume different values at different times, and the program can then produce different results, depending on circumstances, so A is correct.

In a computer language, a reserved word (also known as a reserved identifier) is a word that cannot be used as an identifier, such as the name of a variable, function, or label – it is "reserved from use". This is a syntactic definition, and a reserved word may have no meaning. So, B is incorrect.

Hence, the answer is: Only A is correct.
