Biology
1 answer:

6 0

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.

The muscle that originates on the sacrum and transverse process of each vertebra and inserts on the spinous process of the third
Irina-Kira [14]

Answer:

The muscle that originates on the sacrum and transverse process of each vertebra and inserts on the spinous process of the third or fourth more superior vertebra is the Longissimus muscle

Explanation:

The Longissimus is a group made of three muscles: longissimus capitis, longissimus cervicis and longissimus thoracis. It has the length of the vertebral column.

It is placed in the back, and as the statement says, it originates on the sacrum and transverse of each vertebra. Each of them originates at the transverse elements and insert in the costal ones.

GuDViN [60]

Answer:B convulsions due to constant muscle stimulation

Explanation:

            this is due to  Hyperpolarization at the  axonal cell membrane from continuous influx of sodium ions .

Normally acetylcholine is an exictatory  neurotranmitter, if an inhibitor is applied to block effects of acetylcholinesterase; the action potential will continue to generate , leading to continuous excitation, ( rapid contraction of muscles from increasing action potential, leading to convulsion.

So far  nothing to stop the excitatory neurotransmitter. (acetylcholine stimulation at the receptors of neuromuscular junction of post synaptic neuron.
