The student can measure the number of gas bubbles given off by the algae.
Explanation:
Photosynthesis is a process in which plants make its food (glucose) by absorbing the sunlight, carbon dioxide from air and water from the soil, and release oxygen into the atmosphere. A green pigment in plants called chlorophyll absorbs light and perform photosynthesis.
The rate of photosynthesis increases as a result of increase in the light intensity. Certain types of algae contains different pigments like carotenoids, phycobiliproteins etc in addition to chlorophyll for absorbing light of different wavelength or colors. By using all these pigments, more light energy is converted into chemical energy in the algae by photosynthesis. Thus as the rate of photosynthesis increases, more oxygen bubbles are produced by the algae.
Half of the Moon's surface is always illuminated by direct sunlight, except during lunar eclipses when Earth casts its shadow on the Moon. Just how much of that light we can see from Earth varies every day, and we refer to this as a Moon phase.
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.
