Answer:
<u>Biofilms are</u> defined as complex communities of microorganisms that grow embedded in a self-produced polymeric organic matrix and adhered to a living or inert surface, and that can present a single microbial species or a range of different species
Explanation:
The bacteria that form the biofilm are in what is called sessile form, exhibiting a phenotype different from those of the same cells in unicellular or free form (planktonic form) with respect to the growth rate and gene transcription (Donlan, 2002 ).
<u>
The formation</u> of biofilms is an adaptive strategy of microorganisms, since growth in biofilm offers four important advantages: (I) protects microorganisms from the action of adverse agents, (II) increases the availability of nutrients for their growth, (III) facilitates the use of water, reducing the possibility of dehydration and (IV) enables the transfer of genetic material (DNA). All of these circumstances can increase your survival capabilities. As a consequence, <u>the usual methods of disinfection or the use of antibiotics are often ineffective against biofilm bacteria</u>.
In addition to the risk of contamination, the development of biofilms can interfere with different processes and cause damage to the equipment. In drinking water systems the formation of biofilms can obstruct the pipes reducing their speed and transport capacity causing an increase in energy consumption. The formation of biofilm in heat exchangers and cooling towers can reduce heat transfer and as a consequence its efficiency in the process. The formation of persistent biofilms on metal surfaces can cause corrosion due to acid production by bacteria.
Answer:
Chlorophyll
Explanation:
The chloroplasts is the organelle that process sunlight energy. Chlorophyll is the pigmentation within plants that absorbs sunlight

Thats all I have
Answer:
two sets of magnifying lenses
Explanation:
This is because a compound microscope is a high magnifying microscope that have multiple lenses or two magnifying lenses which help to see or observe or magnify image very well compare to single lense. It is a high power microscope and it has high level of magnification because of the
two magnifying lenses. It produces two dimensional image. The eyepieces and the objective lenses give a very high magnification, a condenser that is below the stage focus the light into the specimen to be viewed.
Answer:
D
Explanation:
When a population is genetically diverse there is a higher probability for some individuals in that population to survive during harsh conditions such as drought due to their highly resistant genes.
