Answer: option D) phylum
Explanation:
The linnaean system of classification from largest to smallest level is as follows:
Kingdom ---> phylum ---> class ---> order ---> family ---> genus ---> specie.
Since the phylum level consists of organisms with less similar characteristics compared to class, order and genus, we can safely say it has most organisms.
Thus, phylum is the answer.
Answer:Temperature- Sensitive Mutation, C
Explanation:
AT 37°C ,<u> The organism transcribe a wild type--C.</u>

Yes. B is the right answer
