Biological Organisms: Living things that are capable of reacting to stimuli, reproduction, growth, and homeostasis. Organisms are classified by taxonomy into specified groups such as the multicellular animals, plants, and fungi; or unicellular microorganisms such as a protists, bacteria, and archaea.
The choices can be found elsewhere and as follows:
1.are soluble and can easily pass through cell membranes
<span>2.contain long chains of amino acids and fatty acids </span>
<span>3.contain atoms of carbon, hydrogen, oxygen and nitrogen </span>
<span>4.are a direct result of dehydration synthesis
</span>
I believe the correct answer is option 1. When most proteins, fats, and carbohydrates are digested completely, they are converted to end products that are soluble and can easily pass through cell membranes. So as to distribute the nutrients needed in different parts of the body.
The answer is wave erosion
