Answer:
The size up of a motor unit varies from<u> just a few fibers</u> in the precise muscles to over a <u>thousand</u> fibers in the powerful muscles
Explanation:
A motor unit can be defined as a single motor neuron comprising all the muscle fibers that are stimulated by that neuron. Hence, when a motor neuron fires an electrical impulse, all the muscle fibers attached to that unit are contracted simultaneously. This motor unit can be smaller in size such as few neuron fibers to eyes for producing precise eye movement. On the other hand, these neurons can be delivering strong impulses to thousands of neuron fibers such as to leg muscles for producing powerful contractions.

Explanation:
Answer:
- Constituyen un alimento mas rico en vitaminas y minerales.
- Cosechas que soportan sequias y condiciones extremas.
- Menor costo de produccion.
- Caracteristicas deseables en las plantas.
- Menor uso de pesticidas.
Explanation:
Los transgenicos, o GMO, son alimentos geneticamente modificados con la finalidad de crear un producto de mayor calidad utilizando genes de otro organismo.
Los alimentos transgenicos suelen ser criticados constantemente por la poblacion ya que muchas personas creen que son dañinos para la salud. Sin embargo, estudios cientificos señalan que son sumamente beneficos en diferentes maneras. Por ejemplo:
- Constituyen un alimento mas rico en vitaminas y minerales que beneficia significativamente a poblaciones que se encuentran en pobreza.
- Cosechas que soportan sequias y condiciones extremas que una planta no transgenica no podria soportar.
- Menor costo de produccion.
- Caracteristicas deseables en las plantas. Por ejemplo, mayor tamaño o fruta mas jugosa.
- Menor uso de pesticidas. Hoy en dia, se sabe que el sobreuso de pesticidas ha ocasionado consecuencias irreparables en el medio ambiente y en la salud humana.
