Answer:
F-: StrR, his+ and met+
Explanation:
the strain Hfr is a high-frequency strain of recombination that includes the F plasmid (fertility factor). Therefore, the whole genome sequence is able to be passed via Hfr to its receiver, but it needs a long duration of physical contact with the recipient because the recipient gets a gene (long time physical contact is seldom attained) and retains the F strain. Also, genomes from the F-cells are not passed backwards to the HF cells. Therefore, only F strain with tolerance to Streptomycin and capable of synthesizing its amino acids on limited media can thrive in this situation. Which is F-: StrR, his+ and met+ recombining.
A. is the answer. Hope this helps you! :p
Lysosomes, which is the organelle that cleans the cell
Answer: Geosphere
Explanation: The geosphere includes the rocks and minerals on Earth from the molten rock and heavy metals in the deep interior of the planet to the sand on beaches and peaks of mountains. For example Sedimentary rocks, Igneous rocks, and Metamorphic rocks.
