The correct answer is: C) exposing the bacteria to an antibiotic that kills cells lacking the resistant plasmid
The plasmids are inserted into bacteria by the process called transformation. Bacteria need to be treated, for example with heat, in order to take up foreign DNA (recombinant plasmid). A inserted recombinant plasmid contains an antibiotic resistance gene, which allows bacteria to survive in the presence of a specific antibiotic. So, this fact is used for the selection of bacteria that are and are not transformed.
DNA would make copies of itself in the synthesis phase of the interphase.
The sperm cell contribute DNA to the embryo. <span>A sperm contains half of the chromosomes needed for the organism - in humans 23
Also the sperm determines if the embryo will be a male or female. If the sperm contains a Y chromosome with the required SRY gene then the embryo will become a male. BUT if the sperm contains an X chromosome then the embryo will be a female.

Their abundance also meant colonists had easy access to protein during bad seasons or harvests, so lobster quickly garnered a reputation as the poor man's meal. They were fed to prisoners, apprentices, and slaves as a way to save money. ... By World War II, lobster was considered a delicacy
