PLEASE HELP ASAP!!Adding earthworms to a compost pile typically increases the rate at which the organic matter in the pile decomposes. A learner wonders whether adding other organisms to the compost pile will have a similar effect on the rate of decomposition. She decides to answer this question by performing an experiment.

• Formulate a valid hypothesis that the learner could test in her experiment.

• Based on this hypothesis, identify the independent variable and dependent
variables for the learner's experiment.

What are the genotypic and phenotypic ratios

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
