What is the role of the F‑factor in conjugation? a. It allows auxotrophic bacterial cells to survive on minimal medium so that conjugation can occur. b. It contains genes necessary for the formation of the pilus. c. It contains genes that force recombination between the donor and recipient chromosomes. d. It degrades the chromosome of the recipient cell after conjugation. It contains genes necessary for replication of the donor's F plasmid.

It contains genes necessary for the formation of the pilus

Explanation:

During Conjugation genetic material is transferred from one bacterial cell (the donor) to another (the recipient) in contact. The pilli (singular. pilus) is the structure used to make contact.

The donor is termed F+, while the recipient is termed F-

The F factor contains genes for the formation of the pilus. The F factor is housed in the donor (F+).

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
