What is the acceleration of a marble in that has a mass of 90kg and a force applied of 60N
miskamm [114]

Answer:

0.6... or 3/5

Explanation:

To find the acceleration, we need to use the acceleration formula:

  • a=F/m

So all we have to do now is plug in the numbers:

  • a = 60/90

Once we divide 60 by 90, we will get the acceleration of the marble.

  • 60/90 = 0.6... (repeating)

Our final answer should be:

0.6... or 3/5

Explain how organisms changes within an environment affect their survival. Specifically discuss the effects of a gene mutation f
maw [93]
<span>Animals gradually adapt to changes within their environment over time. This gives them a better chance of surviving rather than going extinct because of the change. Say there is a gene mutation affecting color within a population of beetles in a rain-forest. All of the beetles used to be red, but now a few of them have experienced a gene mutation and are green. Because they live in a rain-forest, it is likely that the green beetles would blend in with their surroundings far better than the original red beetles, and those red beetles would be wiped out by predators because they are easier to spot. The green beetles would live on and flourish, and their population would increase. Soon there would be few or none red beetles, and many green beetles.</span>

Los riñones son ​​dos órganos ubicados en la cavidad abdominal detrás del peritoneo, a la izquierda y derecha de la columna. Los riñones tienen la función de mantener constante la composición de la sangre, eliminando así las sustancias no deseadas disueltas, como los productos de desecho del metabolismo y los venenos y medicamentos absorbidos a través de los alimentos. El riñón también mantiene el equilibrio ácido del cuerpo a largo plazo, mediante el transporte de carbonato de hidrógeno e iones de hidrógeno. El producto que producen los riñones, una solución de sustancias que el cuerpo ya no puede usar, se llama orina.
