Answer:
The fertility factor or the F factor signifies a plasmid in some bacteria, which allows the conduction of genetic substance from a donor cell to the recipient by the process of conjugation, leading to recombination.
The genotypic difference between the F- cells, F+ cells, and the Hfr cells are that the F- cells are devoid of the F factor, the F+ cells possess autonomous F factor, that is, a segment of DNA, which can replicate autonomously in the cell. In case of Hfr, the F factor is integrated into its chromosomal DNA, thus, they carry an integrated F factor.
In the early stages of development all animals start as a single cell… They divide again and again until... gradually a body emerges…with a front, a back, a top and a bottom. important embryos were fish.
Answer: I would pick scenario 3.
Explanation:
It talks about a relevant factor in a local state. More and more trees are being chopped down today. This can make a community lack natural and fresh air.
The statement above is TRUE.
The Institutional Animal Care and Use committee required that researchers who are using animals for their research study should develop an antibiogram or other appropriate therapeutic panel on infectious strains before using them on animals.
