Hi there!
In the experiment we can identify the variables to determine if the result of the experiment is sound.
Dependent variable - Growth of plants
Independent variable(s) - Medium of watering, being talked to and not talked to
In an experiment you want to have 1 independent variable to determine if that 1 variable is influencing the dependent variable. Because there are two independent variables in this experiment, it is impossible to tell which one caused the plants that were talked to to grow more. As a result, the correct answer would be...
B. Talking to plants may or may not help plants grow faster because the amount of water given was likely different for each group.

Answer:
The scream-y howl is most often heard during the breeding season, in the springtime. It is...horrible. A shrill, hoarse scream of anguish, it sounds more than anything like a human baby undergoing some kind of physical torture. It's thought that this call is used by vixens (female foxes) to lure male foxes to them for mating, though males have been found to make this sound occasionally as well.

Answer:
50%
Explanation:
La información que tenemos es:
Un hombre homocigoto (ee) que carece la posibilidad de enrollar su lengua.
Una mujer heterocigota (Ee). Al tener dos copias distintas de este gen, la mujer puede enrollar su lengua ya que este es un gen dominante (E) sobre el gen recesivo (e) que impide este movimiento.
Si hacemos un Cuadro de Punnett veremos que la capacidad de enrollar la lengua en los descendientes de esta pareja tiene una probabilidad fenotípica del 50% ya que hay un 50% de probabilidades de que su descendencia tenga un genotipo Ee y otro 50% de que sea ee, lo cual se expresa en una probabilidad fenotípica, es decir lo que se puede apreciar visiblemente como resultado de la interacción del genotipo y el ambiente, de con un 50% de poder enrollar la lengua.
