Quiz Read the verse.
aleksley [76]

Answer:

B).  It will leave the next day.

Explanation:

The poem 'Raven' penned by Edgar Allan Poe explores the theme of regret, mental uncertainty, death, and lost love. In the given excerpt, the speaker asserts that 'On the morrow, he will leave me' for the Raven and becomes completely despaired. He becomes completely dejected thinking that 'tomorrow Raven will also leave(die)' like the 'other friends of him along with his hopes have flown(died) before.'

The speaker longed to see his love 'Lenore' in heaven again but this 'nevermore' from the bird makes him accept that the Raven(sense of loss and grief) will stay with him forever. Thus, <u>option B</u> is the correct answer.

How does the large amount of DNA fit into the tiny nucleus within the microscopic cells? please be specific ;) thank you
lys-0071 [83]

Answer:

The DNA is packed in such a way that it fits into the nucleus.

Explanation:

The DNA of each chromosome undergoes coiling, compaction and again coiling to fit into the nucleus.

At the primary level, the DNA is packed around a group of proteins called the histones.

The condensed structure that is formed by the process of coiling is called chromatin. The DNA remains in this shape throughout until it has to carry out replication.

The coiling is only unwrapped at the time of replication of the DNA.
