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.
Answer:
Relatively recent research has shown that heart failure is a significant risk factor for kidney disease. When the heart is no longer pumping efficiently it becomes congested with blood, causing pressure to build up in the main vein connected to the kidneys and leading to congestion of blood in the kidneys, too.

Answer: Likewise in pteridophytes, species also produces haploid spores through haploid stage. In diploid stage the two spores fuse together to form a prothallus which is a diploid stage. Hence, the similarity in the reproductive cycle of fungus and a pteridophyte is that both organisms produce haploid spores and exhibit diploid and haploid stages.
Explanation:
<span>The food web shows a controlled ecosystem. The relationship between the fox and the rabbit is a Predatory (predator/prey) relationship. If the number of frogs in the ecosystem decreased because of human activity, then there’s a possibility that rabbits could be overhunted .</span>
