    of squirrels‚ S. beecheyi and S. variegatus‚ in order to evaluate if SSA can be deemed as a species specific type of behavior. My hypothesis was that squirrels applied the snake skin scent to specific parts of their body in an organized manner. The null hypothesis is that squirrels apply the snake skin scent randomly to parts of their body. My prediction of my hypothesis was that squirrels apply the snake skin scent to body parts that they find prove to be advantageous when trying to escape their

    ppm. After that point‚ the number of fish declines slightly. • Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. When the dissolved oxygen levels increase‚ the number of fish that I observed will also increase until you reach 12 ppm. • What would your experimental approach be to test this hypothesis? A few of the ways that I approached this question. Some options

    Adjusted Concentration of Hydrogen Peroxide on the change in reaction rate of liver catalase. Hypothesis: Null Hypothesis: If the concentration of the Hydrogen Peroxide is changed then there would be no change in the reaction rate. Alternate Hypothesis 1:  I there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction rate of the liver catalase will increase. Alternate Hypothesis 2: If there is an increase in concentration in concentration of Hydrogen Peroxide then the

Chemical signals are picked up by antennae. II. Hypothesis: When given a choice between two identical shelters‚ sowbugs will display necrophobic behavior by aggregating in the shelter that does not contain oleic acid. III.

    et al. 2012). With this information‚ an experimental hypothesis can be formed that the presence of light will cause the redox activity of the spinach chloroplasts to increase‚ while the absence of light will cause this activity to decrease. One possible null hypothesis could be that there will be no significant difference in redox activity between spinach chloroplasts that are under light and in the dark. Therefore‚ the alternative hypothesis must be that there will be a difference in this activity
