Answer:
True statement regarding phytoplankton is :
<u>They are the primary photosynthetic plants in the ocean</u>
<u></u>
Explanation:
Phytoplankton : It is made of two words :
"Phyto" means plants
"plankton" means drift .
Hence Phytoplankton are plants that live in water .They are also known as microalgae and are similar to terrestrial plants because they also contain chlorophyll .
Most phytoplanktons are found on the surface of water so that they can get enough sunlight to prepare their food .
There are two kinds of phytoplankton
a) dinoflagellates (they have tail or flagella)
b) diatoms (they are shell like)
<u>They provide food to many organism living in water . example : jelly fish , shrimps etc</u>
<u>Hence they balance the ecosystem</u>
<u>In this way they are primary producers in water -food chain</u>

0 K in Celsius scale is -273 degree Celsius and in Fahrenheit scale 459 degree F.
The degree of a body's heat or cold is referred to as the gas's temperature. It is stated in temperature units such as, degree Celsius, Fahrenheit and Kelvin these temperature units are interchangeable. To convert Celsius to Fahrenheit ° F = 9/5 ( ° C) + 32, kelvin to Fahrenheit= ° F = 9/5 (K - 273) + 32, Celsius to kelvin K = ° C + 273. to convert Fahrenheit to Celsius ° C = 5/9 (° F - 32) In this question, to convert Fahrenheit to Celsius ° C = 5/9 (° F - 32) = 0-273 K (5/9 - F-32) =459 degree F. and kelvin to Celsius K - 273 = C = -273 degree Celsius
At 8^0C K= 8 + 273 =281 degree Celsius and at 8F , 8= 9/5(k-273) +32 =453 F

To answer this question, you need to know the molecular weight of zinc so you can determine how many mol zinc you have. Zinc molecular weight is 65.38gram/mol. Then the calculation would be: 48.3gram/(<span>65.38gram/mol)= 0.74 mol
Since you are asked the amount of atom, you need to multiply the unit in mole with Avogadro number. The calculation should be: 0.74 * 6.02 * 10^23= 4.45* 10^23 molecules</span>
