its B...
because a composite cell has a cell wall, vacuole, and cell membrane but doesnt include any of the plant cells so i know its B
A virus infects the cell by attaching fibers of its protein tail to a specific receptor on the bacterial cell wall and then injecting the nucleic acid into the host, leaving the empty capsid outside.
In viruses with a membrane envelop, the viral envelop merges with the host cell membrane and is taken in to the host cell by a process called pinocytosis, then releases its nucleic acid inside the host cell to be intergraded with host cell genome.

Answer:
answer is D the answer is D the answer is D
Answer:
C
Explanation:
The origin of replication refers to the site at which DNA replication begins. The process of DNA replication - which occurs prior to cell division - generates a new copy of the DNA.
DNA replication involves unwinding of the DNA double helix, creating a Y shape called the replication fork. The two strands are then replicated, and now there are two DNA molecules, each containing one "old" DNA strand and one "new" DNA strand.
The first stage at the origin of replication is that the enzyme helicase begins splitting apart the strands of a DNA molecule. (C)
The answer is not A, as the two DNA strands are already in the double helix. The answer is not B, as the enzyme responsible for copying the DNA sequence is DNA polymerase, not RNA polymerase. The answer also cannot be D, because although short RNA primers are involved in DNA replication, this does not occur at the origin of replication.
