Explanation:
<em>What is genetic modification (GM) of crops and how is it done? GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants.</em>
Answer:
5.19 m³
Explanation:
Data Given:
initial Pressure P1 = atmospheric pressure
Reported atmospheric pressure = 14.696 psi
Final pressures P2 = 68 psi
initial Temperature T1 = 26 °C
final Temperature T2 = 48 °C
initial Volume V1= 13 m³
final Volume V2 = ?
Solution:
Formula will be used
P1 V1 / T1 = P2 V2 / T2
To calculate volume rearrange the above formula
V2 = (P1 V1) T2 / T1 P2 . . . . . . . .(1)
put values in equation 1
V2 = (14.696 psi x 13 m³) 48 °C / 26 °C x 68 psi
V2 = (191.05 psi m³) 48 °C / 1768 °C psi
V2 = (9170.3 psi m³ °C / 1768 °C psi
V2 = 5.19 m³
So, final volume is 5.19 m³
Answer:
The concentration of an anthracene solution is 
Explanation:
From the question we are told that
The incident beam
is 
The fluorescence intensity is 
The length of the medium is b = 0.875 cm
The molar extinction coefficient is 
The proportionality constant k = 0.30
According to Lambert law the Absorbance of the anthracene solution is mathematically represented as

Where 
and A is the Absorbance
Substituting value


Generally beers law can be represented mathematically as

where c is the concentration of an anthracene solution
Making c the subject of the formula

Substituting 0.875 cm for length = b ,
We have
