Answer: The most likely identity of the substance is iron.
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
![Q=m\times c\times \Delta T](https://tex.z-dn.net/?f=Q%3Dm%5Ctimes%20c%5Ctimes%20%5CDelta%20T)
Q = Heat absorbed=
Joules
m= mass of substance = 11.9 g
c = specific heat capacity = ?
Initial temperature of the water =
= 25.0°C
Final temperature of the water =
= 45.0°CChange in temperature ,![\Delta T=T_f-T_i=(45-25)^0C=20^0C](https://tex.z-dn.net/?f=%5CDelta%20T%3DT_f-T_i%3D%2845-25%29%5E0C%3D20%5E0C)
Putting in the values, we get:
![1.071\times 10^2=11.9\times c\times 20^0C](https://tex.z-dn.net/?f=1.071%5Ctimes%2010%5E2%3D11.9%5Ctimes%20c%5Ctimes%2020%5E0C)
![c=0.45J/g^0C](https://tex.z-dn.net/?f=c%3D0.45J%2Fg%5E0C)
The specific heat of 0.45 is for iron and thus the substance is iron.

Answer:
Production of GMOs is a multistage process which can be summarized as follows:
1. identification of the gene interest;
2. isolation of the gene of interest;
3. amplifying the gene to produce many copies;
4. associating the gene with an appropriate promoter and poly A sequence and insertion into plasmids;
5. multiplying the plasmid in bacteria and recovering the cloned construct for injection;
6. transference of the construct into the recipient tissue, usually fertilized eggs;
7. integration of gene into recipient genome;
8. expression of gene in recipient genome; and
9. inheritance of gene through further generations.
