Answer:
For effect #1, the mutation will become more common (A). This is because with the organism having more children, the trait will be passed around much faster and will spread to surrounding groups of animals. 
For effect #2, the mutation will become more common (A). This is because the disease will kill the animals who do not carry the gene leaving only the animals with the trait, making it much more common
For effet #3, the mutation will disappear (B). This is because the animal carrying the gene will slowly die off. After all,  they will not be able to reproduce and pass the gene to their children. 
For effect #4, the mutation will remain at a low level (C). This happens because since it procures no change there will be no reason to transfer it so it will become a recessive trait in the animals.

Answer:
The vector, that is , the bacterium is encoded by the antibiotic resistance gene.
Explanation:
A recombinant organism is the organism that its genetic makeup has been altered, this means , the organism contains different combination of alleles, that can't be found in either of the parents. This is usually done by deliberately introducing new genetic materials or elements.
The offspring produced by these altered organisms also possess the new genetic material that was initially introduced to the altered organisms.
Bacteria have been the most desired organism for this act, because they are easy to grow and nurture.
