Answer:
A. Activated B - cells divide to form memory cells.
Explanation:
The vaccine contains the dead version of the respective virus, so that virus will be inactive and it will become easy for the WBC to kill it and antibodies will be formed.
This is done because if we get infected by the virus, our body cells (WBC) will remember that how they killed the first entered virus (the dead version) and it will be easy for them to kill the active virus as they know the antibodies which were formed to kill the inactive virus.

Biennial plants</h2>
Explanation:
This plant is a biennial, which means it will just take longer than a season to mature enough to produce flowers.
Since the Sweet William plant did not flower last year when it was planted and this year also it did not bud till the spring. So, we can assume that these plant will need atleast two seasons to mature hence they are biennials.
Depending on the life span, plants are classified as annuals (one season), biennials(two season) and perennials (more than two years).

Answer:
d) 5'-UGUGUGUGUGUGUGUG...-3'
Explanation:
A UG dinucleotide is when UG is repeated.
mRNAs are transcribed and translated as a 5' to 3' molecule. Therefore, the direction should be 5' - 3'.
For the mRNA to be in frame, it must start with UG. The only option that runs 5' - 3' and is in frame for a UG dinucleotide is d.
