Yes it is completely adaptable to many changes it is put through whether it be cold temperatures or hot temperatures. If you’ll notice, algae grows where there is water, no matter what the water is like. This proves the adaptability.

Have a wonderful evening!

Algae have a variety of adaptations that help them survive including body structures, defense mechanisms, as well as reproductive strategies. Some algae have hold fasts that attach to the sea floor and anchor them down much like roots of a plant. Many algae, such as Sargasso, have gas-filled structures called floats.

A student needs to prepare a stock solution for the lab - 500.0 ml of 0.750 m nitric acid. The student is provided with concentr
dlinn [17]

Molarity of concentrated nitric acid = 15.9 M

Volume of the stock solution to be prepared = 500.0 mL

Concentration of the stock that is to be prepared = 0.750 M

Calculating moles from molarity and volume of stock:

500.0mL*\frac{1L}{1000mL}*0.750\frac{mol}{L}  =0.375 mol HNO_{3}

Calculating volume of concentrated nitric acid to be taken for the preparation of stock solution:

0.375mol*\frac{1L}{15.9mol} =0.0236 L

Converting L to mL:

0.0236L*\frac{1000mL}{1L} = 23.6 mL

Volume of distilled water to be added to 23.6 mL of 15.9 M nitric acid to get the given concentration = 5000.0mL-23.6mL=976.4 mL

Therefore, 976.4 mL distilled water is to be added to 23.6 mL of 15.9 M nitric acid solution to prepare 500.0 mL of 0.750M nitric acid.
