Use the box technique, do u know that one? shoiukd have been taught that to answer this problem.
Answer:
B Plasmids are circular, double-stranded DNA molecules that provide genes that may aid in survival of the prokaryotic cell.
Explanation:
Plasmids would be additional chromosomal, double stranded also it is covalently that are closed and circular DNA molecules. It possesses genes that represent some unique attributes to the prokaryotic cell like fertility factor, F plasmid, etc. It may existed as an independent entity that should be within the cell or may be they integrate within the host genome this we called as an episomal in nature
In addition to this, Plasmids plays a significant role in the gene transfer i.e. horizontal that should be within the prokaryotes and are widely used in the recombinant DNA technology like vectors
Therefore, the option b is correct
D because fresh water can always replenish but coal takes millions of years to form

(B)their numbers have increased because of the endangered species act.
(C)their numbers have increased mostly due to captive breeding.
(D)they are still being hunted, and their numbers are declining.
(E)they are an example of protecting biodiversity through the passage of laws.
Answer:
Ways in which members of the gray whale species been affected by efforts to protect biodiversity
(B)their numbers have increased because of the endangered species act.
(E)they are an example of protecting biodiversity through the passage of laws.
<u>Explanation</u>:
Grey whales are nearly 45 meters long baleen whales live in the pacific ocean. Grey whale species were on the line of extinction due to overhunting or whaling in the mid 90's but due to the protection given under Endangered Species Act, its number increased now to 25,000 and in 1994 it was removed from endangered species list. Endangered Species Act's purpose is to protect those animals and plants which are at the risk of extinction and increase their number in the wild. It is strongest law implemented to save biodiversity. So grey whale species have increased due to the Endangered Species Act which is an example of protecting biodiversity through the passage of laws.
