Question

1. when leaving a party, alisha notices that the sidewalk is now wet. if alisha assumes that someone spilled a bucket of water while they were inside, she is making... (al salir de una fiesta, alisha se da cuenta de que la acera está mojada. si alisha supone que alguien derramó un cubo de agua mientras estaban dentro, está haciendo...) a an observation. (una observación.) b. a prediction (una predicción) c. a hypothesis. (una hipótesis.) d. an inference. (una inferencia.) for questions 4 - 5, refer to the following description of an experiment. (para las preguntas 5 - 7, consulte la siguiente descripción de un experimento.) malik, ivan, and dhaymon decide to test what factors influence water absorption by an egg. they remove the shell from 3 eggs by dissolving them in vinegar. they create three different water solutions. one is pure, 100% distilled water, a second is 50% water/50% corn syrup, and the third is 100% corn syrup. the mass of each egg is measured before they are put into a single solution for 24 hours. the mass of the eggs is then measured, and the data recorded below: (malik, ivan, y dhaymon deciden probar qué factores influyen en la absorción de agua por un huevo. quitan la cáscara a 3 huevos disolviéndolos en vinagre. crean tres soluciones de agua diferentes. una es pura, 100% agua destilada, la segunda es 50% agua/50% jarabe de maíz, y la tercera es 100% jarabe de maíz. se mide la masa de cada huevo antes de introducirlos en una única solución durante 24 horas. a continuación se mide la masa de los huevos y se anotan los datos:) 4. this group also recorded an independent variable, which is represented by... (este grupo también registró una variable dependiente, que está representada por...) a. the change in mass of the eggs (el cambio de masa de los huevos) b. the amount of time they were in the solution (el tiempo de permanencia en la solución) c. the ending mass of the eggs (la masa final de los huevos) d. the type of solution the egg is place in (el tipo de solución en la que se coloca el huevo) n this experiment, the dependent variable they are testing is... (en este experimento, la variable dependiente que están probando es...) a. the ending mass of the eggs (la masa final de los huevos) b. the type of solution the egg is place in (el tipo de solución en la que se coloca el huevo) c. the change in mass of the eggs (el cambio de masa de los huevos) d. the amount of time they were in the solution (el tiempo de permanencia en la solución)

Explanation:

• Independent Variable: In an experiment, the independent variable is the one that is changed or controlled to test its effects on the dependent variable. Here, the type of solution (distilled water, 50/50 mixture, 100% corn syrup) is what the experimenters are varying. So for the question about the independent variable, we look for the option that represents what is being changed - the type of solution.
• Dependent Variable: The dependent variable is the variable that is measured and affected by the independent variable. The change in mass of the eggs is what is being measured as a result of the different solutions (the independent variable).

Answer:

• For the independent variable question: D. the type of solution the egg is place in (el tipo de solución en la que se coloca el huevo)
• For the dependent variable question: C. the change in mass of the eggs (el cambio de masa de los huevos)
