Biofilms are often formed on artificial surfaces in the human body. During medical procedures, when artificial joints, intravenous catheters, urinary catheters are placed and injections are made, commensals/mutualists may be introduced into new sites in the body and there they may form biofilms. Which statement below is NOT a reason to explain why such bacteria living in biofilms are so difficult to eliminate? layers of biofilm prevent phagocytes from killing bacteria layers of biofilm acts a a diffusion barrier against antibiotics biofilm stimulates bacteria to grow continually in the log/exponential phase of growth O layers of biofilm acts a a diffusion barrier against antibodies/immunoglobulins bacteria often in stationary phase of growth

Terrestrial Ecosystem

An ecosystem is a collection of interconnected communities. It includes both living and non-living elements of specific strata. The terrestrial ecosystem is solely related to the ecosystem present on the land and covers 25 to 30% of the total earth’s surface area.
