The correct answer is burning of paper. Therefore, burning of a paper is an example of chemical change.

The concept of chemical changes can be explained as changes that take place on the molecular level as the result of a chemical reaction, and as such, a new substance is produced.

<h2>Further Explanation</h2>

Examples of Chemical changes are given below:

  1. Combustion: this involves the burning of a substance or more
  2. The mixture of acid and base
  3. Food Digestion  

The burning of paper is typically an example of combustion, since it involves the burning of a substance. The burning of paper subtly represents a chemical reaction whereby the carbon compounds in the paper are oxidized into different chemicals like carbon dioxide and water vapor.

Some notable examples of chemical change include burning of the gasoline, and iron rusting

However, chemical changes differs from physical changes because, physical changes occur as a result of a change in the physical state of a particular substance. Physical changes could be in the form of evaporation, boiling, or melting.  

A typical example is ice melting into liquid water, and then the liquid is transformed into steam through boiling. Chemical change could result in the formation of new chemical substances unlike physical change where molecules are restructured or rearranged but their internal structures are not affected in any way or form.

The right answer is grilling a burger.

The other answers are physical changes (strumming a guitar , converting matter into energy , melting of copper).

The Maillard reaction is a set of chemical reactions that occur during cooking and that unfold the aromas of food. Maillard (1878-1936) worked on the reactions between amino acids and sugars in the 1910s and recorded his observations and results in his book Genesis of Proteins and Humic Matters. Action of glycerine and sugars on amino acids published in 1912.

The Maillard reaction occurs during cooking. It is partly responsible for the browning and unfolding of aromas. New molecules are formed from amino acids and some simple sugars. They combine in chains and the sets they form reflect the light in such a way that we perceive the surface of the food as brown.

How are chromosomes analyzed within a karyotype
Brrunno [24]
The number and appearance of chromosomes in a cell is called a karyotype. A karyotype can only be seen and studied with a microscope. ... Karyotype analysis can reveal abnormalities, such as missing chromosomes, extra chromosomes, deletions, duplications, and translocations.

The codon AUG specifies the amino acid methionine. What would the tRNA anitcodon be that recognizes this codon?
NemiM [27]

Answer:

UAC

Explanation:

This example portrays that translation, which is the second process of protein synthesis, is about to occur. Translation cannot occur without a special type of RNA called tRNA or transfer RNA.

A tRNA contains a set of three nucleotides called ANTICODON. The tRNA matches an mRNA codon with the amino acid it encodes. The tRNA initially binds to the mRNA and reads the mRNA codon using its anticodon (which is complementary to the mRNA's codon). The actual reading is done by matching the base pairs through hydrogen bonding following the base pairing rule i.e. A-U, G-C. After reading the mRNA codon using its anticodon, it then carries the specific amino acid encoded by that codon it binds to, in order to add to the growing polypeptide chain.

For example, a codon AUG (start codon that signals beginning of translation) will be read by tRNA anticodon, UAC. Since the codon AUG codes for amino acid, Methionine. The tRNA then carries Methionine via its amino acid attachment site and adds to the polypeptide chain (future protein).
