Answer:

The answer is "Option D".

Explanation:

A system or a group of components that communicate with your environment through the sharing of resources, materials, and knowledge with a view to system regeneration and development is known as an Open system. In other words, we can say that it is a system that includes a non-proprietary hardware and advert-based software which enables third parties to add or interact with products to plug in the system and It is freely available on the internet. In this question, the incorrect options can be described as follows:

  • In option A, The management system is used by an organization. It is a paid system that's why it is not correct.
  • In option B, This system enables users in online communities and evaluates one another that's why it is not correct.
  • In option C, This type of system provides resources for upgrade user knowledge. It is a paid system that's why it is not correct.

Sergio039 [100]

Answer:

DNA analysis

Explanation:

DNA is unique for all individuals. DNA analysis is the process of analysing the DNA characteristics of an individual.

DNA profiling is used in forensics to identify the suspects involved in criminal activities.

1. In the process, DNA of the suspects is matched with the DNA found in the site of the crime.

2. If a match is found, it indicates that the genetic relationship exists between the suspect and the criminal or the crim.

3. The order from the court is needed to obtain the DNA of the suspects. The sample can be in the form of blood or saliva.

4. The sample obtained should have adequate cells which contain the DNA.

Issues  

The DNA obtained from the crime site is not pure or proper enough to be ideal for the DNA profiling.

Degraded sample

1. The sample obtained from the site of the crime is not always adequate to obtain the actual DNA.

2. The sample can be contaminated due to the environmental factors.

3. The sample obtained is too less and hence, should be examined accurately in order not to waste the sample.

DNA mixture

4. The sample obtained from the site of the crime is found to contain DNA from more than one individual.

 

Profiling types

DNA profiling can be carried out by using any of the techniques mentioned below.

1. RFLP analysis (  Restriction fragment length polymorphism )

This uses the Southern blot technique. The blot process needs a large amount of the sample. Also, this works well only when the sample is not degraded.

2. Polymerase chain reaction (PCR) analysis

3. STR analysis ( short tandem repeats )

4. AFLP ( amplified fragment length polymorphism )

This is an automated and low-cost process. It is easy to set up and operate which makes this process common in low income countries.

All the methods mentioned above have their own advantages and drawbacks.

13. Value \; after \; increase = Base * Percent \; for \; new \; value

Explanation:

Microsoft Excel is a software application or program designed and developed by Microsoft Inc., for analyzing and visualizing spreadsheet documents.

A spreadsheet can be defined as a file or document which comprises of cells in a tabulated format (rows and columns) typically used for formatting, arranging, analyzing, storing, calculating and sorting data on computer systems.

Some of the terminologies and features of the Microsoft Excel software includes the following;

1. Pie chart: a chart that shows the relationship of each part to a whole.

2. Goal seek: a what-if-analysis tool that finds the input needed in one cell to arrive at the desired result in another cell.

3. Relative reference cell: in a formula, the address of a cell based on the relative position of the cell that contains the formula and the cell referred to in the formula.

4. Data marker: a column, bar, area, dot, pie slice, or other symbol in a chart that represents a single data point.

5. Chart sheet: a workbook sheet that contains only a chart.

6. What-If-Analysis: the process of changing the values in cells to see how those changes affect the outcome of formulas in a worksheet.

7. Rate = \frac {Amount \; of \; increase}{Base}: The mathematical formula to calculate a rate of increase.

8. Order of operations: the mathematical rules for performing multiple calculations within a formula.

9. Formula AutoComplete: the excel feature which, after typing - and the first letter of a function, displays a list of function names.

10. Axis: a line that serves as a frame of reference for measurement and that borders the chart plot area.

11. Category axis: the area along the bottom of a chart the identifies the categories of data, also referred to as the x-axis.

12. Value axis: a numerical scale on the left side of a chart that shows the range of numbers for the data points, also referred to as the y-axis.

13. Value \; after \; increase = Base * Percent \; for \; new \; value: the formula for calculating the value after an increase by multiplying the original value the base by the percent for new value.

Consider a binary search tree where each tree node v has a field v.sum which stores the sum of all the keys in the subtree roote
AVprozaik [17]

Answer:

Each time you insert a new node, call the function to adjust the sum.

This method has to be called each time we insert new node to the tree since the sum at all the

parent nodes from the newly inserted node changes when we insert the node.

// toSumTree method will convert the tree into sum tree.

int toSumTree(struct node *node)

{

if(node == NULL)

return 0;

// Store the old value

int old_val = node->data;

// Recursively call for left and right subtrees and store the sum as new value of this node

node->data = toSumTree(node->left) + toSumTree(node->right);

// Return the sum of values of nodes in left and right subtrees and

// old_value of this node

return node->data + old_val;

}

This has the complexity of O(n).
