1-. CONTESTE FALSO (F) O VERDADERO

Biology
1 answer:

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.

Gene expression might be altered at the level of post-transcriptional processing in eukaryotes rather than prokaryotes because o
Iteru [2.4K]

Answer:

<h2>As transcription and translation occurs in different location in eukaryotes, while in prokaryotes, both the processes occurs at same location,  post-transcriptional processing in eukaryotes. </h2>

Explanation:

The transcription and translation occurs in different location in eukaryotes, while in prokaryotes, both the processes occurs at same location and can be co-translation.

As, in eukaryotes, the transcription occurs in the nucleus and then this transcript have to move in the cytoplasm to translation, so before reaching in the cytoplasm, various modifications occur in this transcript known as post transcriptional modification or processing ( include 5' capping, 3' poly-adenylation and RNA splicing).

As, in prokaryotes, both transcription and translation occur at same place so there is no time for modification for transcript because translation starts as the transcription is still going on.

How can we predict which elements are reactive under normal conditions and which are unreactive?​
mr_godi [17]

Answer:

We can predict or comment about reactivity of elements by taking into consideration their electronic configuration that imparts stability or un-stability to an atom.

Explanation:

Reactivity : It refers to the affinity of a substance to combine with other substance .

Elements are mainly of two types :

  • Metals and Non metals

In terms of metals or non metals it can be defined as tendency to loose or gain electrons .

  • On the basis of it ,we can easily make out or comment about the reactivity of element (metal or non metal ) .Like ,if an element has completely filled outermost shell or we can say have stable electronic configuration then it is already stable .Therefore , it won't react with any other element .
  • But, if its outer shell isn't complete then in order to attain stability it will combine or react with other .Hence , we can say it will be quite reactive .
