We are manipulating one-variable statistics.
To begin:
Turn on the calculator.
Access statistics mode.
Select
<4:ClrList> to clear data from lists, if desired.
,
Enter list
[L1] to be cleared.
,
[L1] ,
Display last instruction.
,
[ENTRY]
Continue clearing remaining lists in the same fashion, if desired.
,
,
[L2] ,
Access statistics mode.
Select
<1:Edit . . .>
Enter data. Data values go into
[L1] . (You may need to arrow over to
[L1] ).
Type in a data value and enter it. (For negative numbers, use the negate (-) key at the bottom of the keypad).
,
,
Continue in the same manner until all data values are entered.
In
[L2] , enter the frequencies for each data value in
[L1] .
Type in a frequency and enter it. (If a data value appears only once, the frequency is "1").
,
Continue in the same manner until all data values are entered.
Access statistics mode.
Navigate to
<CALC> .
Access
<1:1-var Stats> .
Indicate that the data is in
[L1] ...
,
[L1] ,
...and indicate that the frequencies are in
[L2] .
,
[L2] ,
The statistics should be displayed. You may arrow down to get remaining statistics. Repeat as necessary.
Drawing histograms
Note
We will assume that the data is already entered.
We will construct two histograms with the built-in STATPLOT application. The first way will use the default ZOOM. The second way will involve customizing a new graph.
Access graphing mode.
,
[STAT PLOT]
Select
<1:plot 1> to access plotting - first graph.
Use the arrows navigate go to
<ON> to turn on Plot 1.
<ON> ,
Use the arrows to go to the histogram picture and select the histogram.
Use the arrows to navigate to
<Xlist> .
If "L1" is not selected, select it.
,
[L1] ,
Use the arrows to navigate to
<Freq> .
Assign the frequencies to
[L2] .
,
[L2] ,
Go back to access other graphs.
,
[STAT PLOT]
Use the arrows to turn off the remaining plots.
Be sure to deselect or clear all equations before graphing.
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments
_Adnan
But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
There are nothing like emergency disease but there are some common medical emergency which can occur simultaneously like Bleeding,heart attack,Breathing difficulties,severe pain heart stock.Hope you will get my point .Have a nice day ❣️

Innocent
I think infection prevention and control is the avoidance of all things we do that gives out break of infections and promotion of health practices that promote life
