Spores and seeds have basically the same function-dispersal-but are vastly different because spores (D) are unicellular; seeds are not.
<h3>What are unicellular organism?</h3>
A unicellular organism can be regarded as single-celled organism, which are those organisms that consists of a single cell.
This is different from multicellular organism because it consists of multiple cells however Organisms can be selected base on general categories which are prokaryotic organisms and eukaryotic organisms.
It should be noted that Spores and seeds have basically the same function-dispersal-but are vastly different because spores (D) are unicellular; seeds are not.
Therefore option D is correct.

Answer:
The correct option is b. DNA ligase
Explanation:
DNA ligase is an enzyme that joins DNA fragments. If two DNA fragments or molecules have complementary ends, the ligase can join them together to form a single and intact DNA molecule, without interruptions. This is because the ligase enzyme seals the space between the molecules to form a single DNA fragment.
The others enzymes have different functions:
DNA helicase is characterized by separating DNA from double strands into single strands and acts in DNA replication.
ATP methylase plays an important role in DNA replication when determining the beginning of replication that has already been replicated or not.
DNA polymerase is an enzyme that is responsible for catalyzing the polymerization of the new strand of DNA during the replication of this molecule.
Chesapeake bay is an area that has suffered from overharvesting and eutrophication. Eutrophication is an enrichment of water by nutrients salts that causes structural changes in the ecosystem such as increased formation of algae and aquatic plants, depletion of fish species among other effects. The greatest source of nitrogen and phosphorus in a Chesapeake bay is agriculture
Relative dating concerns the dating of fossils by using stratum (layers in the rock) to find the estimated age.
Absolute dating is finding the age of a fossil by using radiometric methods, such as fluorine dating or half-life dating; which is more accurate than relative dating.
