Answer: Control group is first one, as it is being used to compare. One constant are the math problems, as they are the same. The other one would be the time allowed to solve the questions.
Answer/Explanation:
When cell absorbs light energy it begins <em>photosynthesis </em>(process by which sunlight is transformed into food for the plant). The light energy is absorbed by the <em>chloroplast. </em>Photosynthesis happens and oxygen, water, and glucose are produced. These are transported to the mitochondria where <em>ATP</em> (chemical energy) is released. All that is left is Carbon dioxide and water which are moved back to the chloroplast. This process between the mitochondrion and the chloroplast is cellular respiration.
It is believed that insects are so successful because they have a protective shell or exoskeleton, they are small, and they can fly. Their small size and ability to fly permits escape from enemies and dispersal to new environments. ... In addition, insects can produce large numbers of offspring relatively quickly.
