What type of reaction happens when amino acids combine to form proteins and water is released?

When two amino acids form dipeptide through peptide pond, this type of reaction is called condensation reaction.

The reaction produce two amino acids and a molecular of water.

The resulting amino acids are joined by polypeptide chain.

The amide bond is synthesized when the carboxyl group of one amino acid molecule reacts with the amino group of the other amino acid molecule, causing the release of a molecule of water (H2O), hence the process is a dehydration synthesis reaction.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
