The complete question is as follows:
What is the independent variable in this strawberry experiment?
O the type of pots
O the number and weight of strawberries produced
the potting soil
O the water schedule
O size and age of plants
Answer:
The correct answer is - the watering schedule.
Explanation:
Independent variable is the variable or the factor which is changed or manipulated during a study or experiment to find the effect on the dependent variable.
The variable that is manipulated in this experiment is the watering schedule and the aim of the experiment is also finding the role of the effect of the watering schedule on fruit production.

Answer:
Potential and kinetic energy
Explanation:
Hydropower use to potential energy and kinetic energy to produce electricity. It uses the potential energy of the water store in dam and this potential energy is the energy posses by an object at rest. The potential energy is now converted to kinetic energy when the water begin to flow through it pipes and began to turn the turbines which then convert it to mechanical rotation of the turbine.
Answer:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
