<span>C dinoflagellates

</span><span><span>A flagella (or flagellum plural) is a long strand like structure that is located in the front end part (more like a tail in front). It flips to the left and right in order for the organism to move. It is connected to the reservoir, which contains the storage of food for the organism.<span>

</span></span>These unicellular organisms are responsible for breaking down materials in the earth. They assist with the decomposition of the dead and decaying matter that can be found on the earth's surface. This break down also makes up natural fertiliser for the plants which then grow up fertilised. These unicellular organisms are also an essential part of the nitrogen cycle. They change the nitrogen from the environment and turn them into absorbable nitrates for the plants, which is an essential part of the plants' food.

Please help!!
Nikitich [7]

Answer:

1. d.water comes "out of" or "exits" the reaction

2. a.energy goes "into" or "enters" the reaction

3. Path A

Explanation:

1) Peptide bond synthesis is dehydration reaction which means water is "dehydrated" meaning released when the reaction occurs.

2) Anytime we want to join things together we gotta use energy, these processes are anabolic reactions such as making sugars, proteins, lipids, in our cell. Since we are making protein here, we need to put energy into the reaction.

3) Path A is hydrophobic b/c they directly diffuse thru cell membrane to attach to intracellular receptor.

My best attempt, hope its right.
