Chemical change. Compounds and molecules in the milk are reacting with the air and breaking down and forming new molecules.
The addition of heat energy to a
system always causes the temperature of that system to increase. This is always
true because you are adding heat of a substance to increase its temperature. For example, you are going
to drink a cup of coffee. And you wanted it hot to boost your attention. So you
have to use hot water. In order for your water to become hot or warm, you need
boil it in a kettle. Note that you are going to use an electric stove. The
electric stove gets it energy from the source giving it a hotter temperature to
the water in the kettle. You are applying heat energy to warm the water. So,
the statement is true.
Amino acids.
Amino acids group together to form proteins. Enzymes are protein in nature. Thus the substrate is an amino acid.

Not all DNA codes for proteins
Explanation:
- DNA (Deoxy Ribonucleic acid) is the genetic material present in all the eukaryotes.
- An experiment conducted in the 1960s proved that most parts of DNA are composed of long strings of repeated sequence which does not code for proteins.
- The process involves in coding for a protein are the transcription of DNA to RNA, then translation followed by protein synthesis. There are enzymes involved in these processes.
- As per the latest study, it states that only 1 per cent of genes code for proteins rest 99 per cent is called the non-coding DNA.
