Answer:
Pakicetus had an ear bone with a characteristic specific to whales and a distinctive long skull shape of a whale's.
Pakicetus
• Pakicetus was a wolf-sized animal and was a carnivore that at certain occasions consumed fish had exhibited features of its anatomy that associated it to the modern cetaceans, porpoises, whales, and dolphins.
• It had the body of a land animal, however, its head exhibited the distinctive long skull similar to a whale.
• With time, the fossils also showed that Pakicetus possessed an ear bone with a characteristic specific to whales.
Thus, pakicetus can be considered as the first whale who exhibited certain similar anatomic features like that of a whale.

Answer:
Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus. Changes in chromatin structure are associated with DNA replication and gene expression.

Answer:
Original strand is the old strand and replicated strand is new strand.
Explanation:
DNA is replicated by the semi-conservative way which means the new strand is replicated over the old strand and one DNA duplex has one new strand and one old strand. So the original strand is the old strand and the replicated strand is the strand that is synthesized over the original strand.
In DNA the replicated strand is made by adding nucleotides complementary to the opposite nucleotide present in the template or original strand. Adenine and thymine make complementary base pairing with each other and guanine and cytosine makes complementary base pairing with each other.
