Answer:

they grow, reproduce and die.

Explanation:

Microorganisms are a way of life that cannot be visualized without the aid of a microscope. These tiny beings can be found in the air, on the ground, and even in man. These tiny beings are not all the same, they can be very different in size and way of life. However, they all have in common a very simple structure and the impossibility of being seen without the use of a microscope. In addition, microorganisms can represent some characteristics of life, since as well as living beings in gereal they grow, reproduce and die.

How many pounds in a 3.00 l bottle of drinking water?
slava [35]

Answer:

             6.61 Pounds

Solution:

Step 1: Calculate Mass of Water as;

                        Density  =  Mass  ÷  Volume

Solving for Mass,

                        Mass  =  Density  ×  Volume   ------ (1)

As,

                        Density of Water  =  1 g.cm⁻³

And,

                        3 L of Water  =  3000 cm³

Putting values in equation 1,

                        Mass  =  1 g.cm⁻³  × 3000 cm³

                        Mass  =  3000 g

Step 2: Convert Grams into Pounds;

As,

                        1 Gram  =  0.002204 Pounds

So,

                        3000 Grams  =  X Pounds

Solving for X,

                      X =  (3000 Grams  ×  0.002204 Pounds)  ÷  1 Gram

                      X =  6.61 Pounds
