El paramecio es un organismo unicelular que vive en agua dulce. En el citoplasma el paramecio contiene mayor concentración de sales disueltas que el medio líquido en el que vive. Esto significa que el medio es hipotónico con respecto al de la célula, y por lo tanto, el agua tiende a entrar al paramecio, tratando de equilibrar la concentración de sales en ambos lados de la membrana. En los paramecios las vacuolas se encargan de expulsar el exceso de agua. a. ¿Qué le sucedería al paramecio en este medio si sus vacuolas no cumplen su función? b. Escribe tu hipótesis y realiza predicciones haciendo dibujos explicativos

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.
