There are two things that cause ocean water to become denser, and those are b) the salinity of water and low temperatures.
The more salt there is, the denser the water will be - take the lake Dead Sea in Israel, Jordan, and Palestine for example.
And the lower the temperature, again, the denser the water will be - the deeper you go into an ocean, it will be more difficult to move around due to density and other things.
Cell wall, chloroplasts, and central vacuole
Five cellular targets of antibiotics were exploited withinside the improvement of antimicrobial drugs: cell wall synthesis, protein , ribonucleic acid , (DNA) , and middleman metabolism.
<h3>How do antibiotics acts as resitance?</h3>
The principal mechanisms of resistance are: proscribing uptake of a drug, amendment of a drug target, inactivation of a drug, and lively efflux of a drug. These mechanisms can be local to the microorganisms, or received from different microorganisms.
In principal, there are 3 principal antibiotic objectives in bacteria: The cell wall or membranes that surrounds the bacterial mobileular. The machineries that make the nucleic acids DNA and RNA. The equipment that produce proteins (the ribosome and related proteins).

A/Cell membranes and cell walls are selectively permeable and aid in communication.
Explanation:
Cell Membranes or cell wall have phospholipid bi layer which functions
as a selectively permeable barrier that separates an internal
environment from an external one. They are selective permeable through
passive process (concentration gradient) allowing certain molecule
diffuse into cells
