Answer:
gene flow is the transfer of genetic variation from one population to another.
option D
A substance that can be used or prepared for use as food
Answer:
gene encoding enzymes for glycolysis.
Explanation:
Plasmid may be defined as an extra chromosomal circular DNA that replicate independently of the main chromosomal material. Plasmid are generally used for the manipulation of genes in molecular technologies.
Plasmid can encode gene for toxins, antibacterial resistance and for the unusual substrate degradation. The plasmid cannot code enzyme for glycolysis because these enzymes are already present in the host organisms. Glycolysis enzymes are independent on the plasmid regulation.
Thus, the correct answer is option (3).
All the options are correct.
1. New ways to preserve and transport blood for blood transfusions were discovered.
2. Blood transfusion safety was improved.
3. Scientists discovered that elements of blood could be separated by centrifuge.
4. Scientists discovered that plasma could be preserved by freezing.
