Suppose that a botanist is interested in the effect of light on plants. In an experiment she conducts, 50 individual plants of a single species of flowering plant are grown for 60 days under different lengths of artificial daylight in a greenhouse. The plant species has flowers that can be either white or pink, depending on the genetics of the parent plants. The amount of water and fertilizer provided to each plant is constant. At the end of the experiment, the size of each leaf of every plant is measured. The independent variable in this experiment is the Group of answer choices leaf's size. duration of artificial daylight. flower's color. duration of the experiment.

Duration of artificial daylight.

Explanation:

A variable used in an experiment that is not affected by other variables and at the same time determines the value of other variables is termed as the independent variable. In a particular experiment the independent variable is the one that can only be controlled or manipulated by the person who is carrying out the experiment. In the given situation, the amount of water and fertiliser is constant and not changed by the experimenter however, it is the length of the artificial daylight that is being changed by the experimenter and the size of the leaf of the plant is being measured in response to the duration of the artificial daylight.Hence, the duration of the artificial daylight is the independent variable used in the experiment.

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.

Female luna moths (actias luna) attract males by emitting chemical signals that spread through the air. a male hundreds of meters away can detect these molecules and fly toward their source. the sensory organs responsible for this behavior are the comblike antennae visible in the photograph shown here. each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. what predictions does your hypothesis make? design an experiment to test one of these predictions.
