Answer:
option A
Explanation:
The correct answer is option A.
Carbon-14 is a dating technique used to estimate the age of the bone which is less than 40,000 years old.
When an organism dies the carbon 14 is converted into nitrogen 14 so, we can estimate the age of the bone.
This method is used by the archaeologist to find the age of the dead and decay animals present inside the earth's surface to study the earth and creature who have lived on earth.
Answer:
Option b) Hydrophobic interactions between phe106 and ile108 of one monomer and ile272 and leu273 of the other monomer. Ionic bonds between arg96 and arg103 of one monomer and glu300 and glu304 of the other monomer.
Explanation:
In the structure, there are ionic hydrogen bonds and salt bridges between the 42, R221, and D24. These interactions have a dynamic impact on the activity and structural stability of the protein nature.
The hydrophobic interactions at the interfaces also contribute in the stabilization of the protein structure.
Answer:
DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are. Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Explanation:
I believe the answer is decomposition. please let me know if that is correct.
In order to increase the rate of diffusion of materials in and out of the cell, the following modification can be done to the cell:
1. the shape of the cell can be changed to one that has high surface area to volume ration, for example sphere.
2.The cell can also divide into two in order to increase the surface area to volume ratio.
