How do hollow bones improve the survival of birds? (1 point )

Chemistry
1 answer:
OLEGan [10]2 years ago

Answer:

Hollow bones allow the birds to fly. They're quite dense, and that density allows for flight! Because we humans do not have hollow bones, our bodies are much too heavy to fly on our own. If we did, we'd probably be able to fly.

Consider this initial-rate data at a certain temperature for the reaction described by N2O3(

We can have the relationship:

However,

Also, we assume m=1 which is the order of the reaction.

Thus, the relationship is simplified to,

r(t)/r0(t) = 2

r<span>(t)</span>=k<span>[<span>N2</span><span>O3</span>]</span>

Which of the following is an accurate example of how the water cycle can influence local weather? A. An increase in evaporation
irina1246 [14]

The answer is; A

During a hot day, the land heats up faster than the waters. The air on land becomes warm and less dense fast and begin to rise in the atmosphere. The air on the ocean with is still cooler and denser moves in to replace the rising on land air. This causes a sea breeze. The sea breeze carries with it, moisture. The hotter the day the higher the humidity. When the air goes inland, it causes precipitation when it rises,  cool, and condenses.
