Plasmids have a high probability of being present in the new generation of cells by all of the following EXCEPT: A. being presen
t at a high number so that some copies will end up in each new cell after cell division B. by having a mechanism to allow for segregation of plasmids into daughter cells C. carrying a gene or genes essential for survival D. all are plausible mechanisms that could ensure maintenance of a plasmid in the population
Answer: C. carrying a gene or genes essential for survival
Explanation:
A plasmid can be defined as the small, extrachromosomal, double stranded DNA that can be found in the bacterial cell and in other prokaryotes. The plasmid DNA remain physically separated from the chromosomal DNA. The plasmid DNA can replicate independently.
The plasmid DNA carries genes which can facilitate the survival of the organism. This gene may provide the selective advantage like antibiotic resistance to the bacteria or any other organism. But the gene may not be essential for the survival of the organism.
Answer:These include closing the doors and windows in the evenings to prevent entry of mosquitoes into human dwellings; using mosquito repellant lotions, creams.
" positive feedback loops push the organism further out of homeostasis, but may be necessary for life to occur. Homeostasis is controlled by the nervous and endocrine systems in mammals." (Lumen Learning)
Transport proteins- an example of a protein in the plasma membrane is integral proteins, which main function is to transport molecules across the membrane. Hope this helps :)
