The correct answer is - c. Coral reefs provide resources for aquatic organisms and derive resources from other organisms as well.
The corals are essential part of the marine ecosystems. They are feeding upon zooplankton, but also their polyps get sugar that is produced by the algae living on them. Also, the corals provide much needed shelter for lots of marine animals, but also are on the menu of some, like the starfish for example.
Answer:
The first law of thermodynamics states that energy is always conserved. The second law states that within a closed system (where only energy can enter or leave the system, while matter cannot), the amount of randomness or disorder, known as entropy, must increase to some maximum value and remain constant
I believe the answers are

- can be prevented with immunization
- can be treated with antibiotics
Answer:
Explanation:
There are differences between Eukaryotic and Prokaryotic cells. A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multicelled organism. Both plant and animal cells are eukaryotic cells, but there are differences between the two. A plant cell has a cell wall while an animal cell does not have a cell wall. A plant cell is a regular shape and an animal cell is an irregular shape. Both plant and animal cells have a nucleus. There are just a few examples of the differences between Eukaryotic and Prokaryotic cells.
Answer: Amino acids; peptide
Explanation:
20 different AMINO ACIDS link together to form chains. A protein is composed of one or more of these PEPTIDE chains which are twisted and folded into a particular shape.
There exists 20 amino acids capable of forming protein in the Human body. At least two amino acids are joined together by a peptide bond to form polypeptide chains that are then held together by hydrogen bonds in twisted alpha helical structures to form proteins.
Answer:Amino acid, polypeptide/polynucleotide chains
Explanation: Amino acids are usually the building blocks of protein hence,every protein is made up of one or more amino acids.
A protein consist of one or more polypeptide chain that is folded into a helix shape. This shape is to prevent the easy degradation of the components that makes up the polypeptide because it is water loving and can easy degrade.
