Answer:
Coral reefs protect coastlines from storms and erosion..
GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants. The seeds produced by these plants will inherit the new DNA
Viruses are at the heart of this century-old debate. Viruses<span> are parasites that infect plants, animals, fungi and bacteria. They consist of genetic material surrounded by a protein coat and are unable to grow or reproduce without a host. The classification of viruses has confused scientists for nearly 100 years. Originally they were viewed as poisons. In fact, the word ''virus'' is Latin for ''poison.'' They have since been viewed as living creatures, then mere bio-chemical compounds, and, most recently, somewhere in between chemical compounds and lifeforms.</span>Non-cellular life<span> refers to organisms, such as viruses, that exist without any cells, and it is a very controversial topic. The cell theory, which is one of the fundamental tenets of biology, states that all living things are composed of cells and that cells are the basic units of life. So the idea that something can be considered alive without having cells is an issue that is up for debate.

The type of molecules made from amino acids are:
<u>Proteins </u>
Explanation:
- Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues
- Amino acids are the building blocks of proteins. The beads (amino acids) are connected together by a string (bond), which forms a long chain (protein).
- Therefore, a protein is "intact" or "whole." Proteins are connected together; free amino acids are not.
- Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.
- Proteins are made up of smaller building blocks called amino acids, joined together in chains.
- There are 20 different amino acids. Some proteins are just a few amino acids long, while others are made up of several thousands. These chains of amino acids fold up in complex ways, giving each protein a unique 3D shape
- They also assist with the formation of new molecules by reading the genetic information stored in DNA
