Answer:
The correct answer is option - e. all of the above are useful traits.
Explanation:
A cloning vector is a small segment of DNA that can be established stably in an individual organism and able to internalize a foreign DNA for cloning purposes. The cloning vector could be taken from different organisms such as plasmid of a bacterium, or DNA from a virus. A cloning vector must possess some characteristics -
The cloning vector must be self-replicating ability in the host cells, it should be small in size with restriction site for the restriction endonuclease enzymes in it. The replication character of the vector should not interfere with the internalized DNA fragment. The presence of marker genes in the vector is also a property that is helpful in identifying of recombinant cells.
Thus, the correct answer is option - e. all of the above are useful traits.

Answer:
Reproductive isolation occurs faster in deep-water shrimp than shallow-water shrimp.
Explanation:
Though in the same territory, the blockage caused by the isthmus would quickly and permanently isolate shrimps living in the deeper parts of the water, thus making them unable to breed. This situation would then caused lack of gene flow within the deep-water shrimps , and the emergence of new species that are genetically different (diverge) from one another
The shallow-water shrimp, on the other hand, experience minimal isolation due to the shallowness of water, and could still breed with one another. Thus, they experience a relatively lower reproductive isolation
Answer:
The difference is:
a) Positive feedback increases a change while negative feedback reduces a change.
b) Positive feedback occurs specific situations while negative feedback occurs in the body.
c) Positive feedback break down the homeostasis while negative feedback maintain the conditions of homeostasis.
d) Positive feedback has less frequent mechanism while negative feedback has more frequent mechanism.
e) Positive feedback enhances change while negative feedback resists change.
f) Positive feedback has a wider range while negative feedback has a narrow range.
