What change could a student measure to collect data about the rate of photosynthesis in a certain type of algae when it
is exposed to different colors of light?
the temperature of the water surrounding the algae
the number of ribosomes in the green algae cells
the color of algae
the number of gas bubbles given off by the algae

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.

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.
