A subduction zone is where one tectonic plate is sliding under another one. It is not usually a continuous smooth motion, but an intermittent cycle of building pressure of one plate against the other and then a "slip" or movement that relieves the pressure by moving the plates. This movement is called an earthquake.<span />
Answer: Option D."Kyoto Protocol"
Explanation:
The Kyoto Protocol is the first international agreement on climate change that was originated in Kyoto (Japan) on December 11, 1997 and entered into force on February 16, 2005.
Kyoto Protocol was linked to the United Nations Framework Convention on Climate Change, that allows the commitment of parties to reduce gas emission.
In the first commitment period, the community was binded to reduce green house gas emissions to an average of five percent in comparison to 1990 levels. In the second commitment period, parties binded to reduce green house gas emissions to an average of 18 percent below 1990 levels in the eight-year period from 2013 to 2020.
Hence, the correct option is D.
The cell membrane in humans and animals behaves most like the second option. A police officer who allows select people to enter and leave a crime scene. The cell membrane allows particles through to the cell that are vital for the cell to function, while keeping out unwanted substances.

Answer/Explanation:
If a protein has a quaternary structure it is formed when many subunits get together.
- true. The quaternary structure of a protein is the final stage in its assembly, when structures from multiple polypeptides come together, forming a multi-subunit protein (e.g. a dimer if 2, a trimer if 3 and so on)
Monomers form the secondary structure of proteins.
- false, they form the tertiary structure
The charges on the functions groups of the amino acids creates the beta pleated sheets and alpha helix structures that are the secondary level of structure in proteins.
- false, it is mostly the peptide backbone that causes the alpha helices and beta sheets to form
The order of the amino acids is the primary structure of proteins. - true. The amino acid sequence linked together by peptide bonds is the polypeptide sequence, which then forms increasingly complex structures when folded.
The tertiary structure of proteins is formed when the B sheets and alpha helices organize themselves into a more complex shape. - true. These complex structures can further interact with one another to form increasingly organized domains. The amino acid side chains possess different properties that form different bonds with one another.
The primary structure of proteins is formed from the amino groups on the proteins. - false, the primary structure is formed by the sequence of amino acids in the chain, determined by the mRNA sequence from which the protein is synthesised.
