Bacteria with the ability to break down certain types of plastic are placed with a colony of e. coli bacteria that lack this ability. plasmid transfer occurs between the two colonies of bacteria and some of the e. coli gain the ability to break down plastic as well. what does this information demonstrate? a. plasmids are proteins which build tissues. b. plasmids are lipids which provide energy for the cell. c. plasmids are nucleic acids which can pass on traits. d. plasmids are carbohydrates which provide structural support

The answer is; C

Plasmids are conferred through horizontal gene transfer in bacteria.  The ‘male’ bacteria develops a structure called pili that then attaches to the ‘female’ bacteria. It then transfers it’s replicated plasmid to the ‘female’ bacteria in a process called conjugation. This bacteria will hence have desirable traits that are coded for by the transferred genetic material ,such as antibiotic resistance, after a process called recombination.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
