1-. CONTESTE FALSO (F) O VERDADERO
jeka57 [31]

Answer:

A) Falso, cuando un resorte se estira, este comienza a acumular energía potencial. Al soltar el resorte, este tratara de volver a su forma natural, consumiendo la energía potencial y transformándola en energía cinética.

B) Falso. Potencia esta definido como la cantidad de trabajo efectuado por unidad de tiempo, a mayor potencia, mas rápido se completa un trabajo.

C) Verdadero, el trabajo es escalar, pues resulta de un producto punto entre dos vectores, la fuerza y el desplazamiento.

D) Falso, el cambio en la energía cinética de un cuerpo es igual al trabajo neto aplicado sobre ese cuerpo. Es decir, si le aplico trabajo a un cuerpo, estoy cambiando su energía cinética.

E) Falso, la fuerza del vagón sobre los pasajeros NO es constate, ya que esta fuerza esta relacionada con la velocidad a la que se mueve el vagón, y sabemos que la velocidad del vagón va cambiado durante el trayecto (podemos experimentar esta fuerza al pasar de una horizontal a una pendiente muy pronunciada, ya que hay un gran cambio de velocidad, y si hay cambio de velocidad, hay aceleración, y por la tercera ley de Newton, si hay aceleración, hay fuerza), pero si es verdad que esta fuerza es un factor importante al diseñar una montaña rusa.

Explain why the hormones attach to the target cell and not to other cells
Aleonysh [2.5K]
Because the target cells have the correct attachment for the hormone cells. For example, when you have a remote control you place the battery in the correct position to operate. Same way with hormones, they're wired to work with a certain type of cell because of how they work.

The alga Powellsia pikocensis is typically a unicellar species. Occasionally it is multicellular; clusters of cells have been fo
marin [14]

Answer:

The correct answers are statements a and b.

Explanation:

The clusters of cells can exhibit the capability of evolution if it fits into three conditions, that is, possessing the tendency of reproducing, variation in clusters and that variation need to be hereditary, and the clusters shall pass fitness, that is, clusters must be abundant in comparison to the single cells.  

The given first statement indicates that clusters possess the tendency to reproduce by the process of fragmentation. Thus, it supports the hypothesis that the clusters possess the tendency to evolve. The second statement indicates that clusters are more fit, therefore, it also supports the hypothesis.  

The third statement is contrary to the hypothesis. Therefore, it does not support the hypothesis. The fourth statement is in contrast to fitness, more abundancy shows more fitness. Therefore, it also does not support the hypothesis. Hence, the correct statements are a and b.
