The correct answer is - C and D.
The principle of original horizontality means that the rock layers have been order by age, with the layers at the top being the youngest, while the layers at the bottom being the oldest.
In this picture it is little hard to tell which rocks belong to the same layer from first look because there are multiple twists and turns, an uneven surface, caused by pressure on the crust.
By carefully examining the image though, we can trace the layers more properly and see which ones are younger, which older, and which have the same relative age. In this case, we can see that the markings C and D are actually on the same layer of rocks, thus being a good indication that they have the same relative age.
Un mol de un gas monoatómico cuyo calor absorbido es 40.0 J y cuyo trabajo recibido es 200.0 J experimenta un cambio de energía interna de 240.0 J.
Tenemos un mol de un gas monoatómico en un recipiente con un pistón y suceden las siguientes transferencias de energía:
- El gas absorbe 40.0 J de calor, ya que Q > 0.
- El gas recibe 200.0 J de trabajo, ya que Q > 0.
Podemos calcular el cambio de energía interna del gas (ΔU) usando la siguiente fórmula.

<em>7. Considere un sistema que contiene un mol de un gas monoatómico retenidito por un pistón. ¿Cuál es el cambio de energía interna del gas, Q: 40.0 J y W: 200.0J?</em>
I think the correct answer from the choices listed above is the second option. Lysosomes can be compared to the recycling and garbage centers of a city. This can be justified since they <span>digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.</span>
It's hard to explain but it would like, be less wild than the seasons we have today.
