Tresset [2298]

The term that correctly describes the transfer of organic molecules, inorganic ions, vitamins, and water from the digestive tract's lining into the surrounding fluid is absorption. This process is crucial in digestion because the absorbed materials are subsequently delivered to the body's cells through the circulatory system.

Convert enzyme concentrations of 2.5%, 5.0%, and 10% to ppt units.

lana [2441]

Answer:

2.5 x 10¹⁰ ppt

5.0 x 10¹⁰ ppt

1.0 x 10¹¹ ppt

Explanation:

The term ppt denotes parts per trillion, meaning how many parts of the enzyme are present in 1 trillion parts. Percentage denotes the number of parts per 100 units. To convert the provided values from percentage to ppt:

$\frac{2.5}{100}=\frac{a}{1,000,000,000,000}\\a=2.5 *10^{10}\ ppt\\\\\frac{5.0}{100}=\frac{b}{1,000,000,000,000}\\b=5.0 *10^{10}\ ppt\\\\\frac{10}{100}=\frac{c}{1,000,000,000,000}\\c=1*10^{11}\ ppt$

The concentrations in ppt are:

2.5 x 10¹⁰ ppt

5.0 x 10¹⁰ ppt

1.0 x 10¹¹ ppt
