a. A science experiment is conducted to investigate the effect of light intensity on the growth of plants. The researcher hypothesizes that increasing the light intensity will lead to increased plant growth. To ensure accurate and reliable results, the researcher sets up the experiment with the following design:

Type 1: Plants exposed to high light intensity (12 hours of direct sunlight per day).

Type 2: Plants exposed to normal light intensity (6 hours of direct sunlight per day). Both types of plants are given the same amount of water and nutrients, and the temperature is kept constant. The height of the plants is measured after two weeks.

What is the objective of including type 1 plants in this experiment?

a)

i) To control for the influence of varying light intensities on plant growth.

b)

ii) To ensure uniform water and nutrient supply to all plants.

c)

iii) To assess the hypothesis that elevated light intensity results in enhanced plant growth.

d)

iv) To maintain a consistent temperature throughout the experiment.
