Bacterial conjugation
Drag each phrase into the appropriate bin depending on whether it applies to an F+ cell, an Hfr cell, or an F- cell. (Remember that we are only considering conjugation involving the F factor here, and not other mechanisms for transferring genetic material.)
F+ cell:
1) carries the F factor in a plasmidmay
2) may donate a plasmid to another cell

Hfr cell:
1) carries the F factor in its circular chromosome
2) may donate genes from its chromosome to another cell

F- cell:
1) may become F+ after conjugation with an F+ cell
2) may become recombinant after conjugation with an Hfr cell
3) may receive genetic material, but cannot donate genetic material

Yes, these are correct.

Explanation:

Bacterial conjugation is the bacterial counterpart of sexual reproduction. Also known as horizontal gene transfer, it involves the transfer of genetic material from one F+ or Hfr bacterium to another F+ or F- bacterium.The F or fertility factor is a crucial component of the bacterial plasmid and it accounts for the development of sex pili which are important for conjugation. An F+ cells contains the F-factor incorporated into its plasmid, whereas an F- cell lacks the F-factor and therefore cannot participate in conjugation.Conjugation between an F+ and F- cell can result in the transfer of the F-factor to the F- bacterium.An Hfr bacterium contains F-factor incorporated into its circular genome.

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.

Ribonuclease activity is a type of nuclease that catalyzes the degradation of rna into small components.
