breathing involves the movement of diaphragm and Rib cage



true or false​

Answers

Answer:

True

Explanation:

It's a true statement as,

When we inhale the diaphragm moves downwards and the rib cage moves upwards and outwards to let enter the outside air containing oxygen come in.While we exhale the diaphragm comes to its position and the rib cage move downwards and inwards to let out the inside carbon-dioxide and other games out.

Hence, we can conclude that breathing involves the movement of diaphragm and Rib cage.

Yes,very true! This is very true because out lungs are around our rib cage,and our lungs is where we breath. For example,right now take a breath in.....Hold.... and out. And one more time. Your lungs are moving in your rib has you do that!

Hope this explains better :)

Answer:

The P waves undergoes compression and dilation during motion in its direction of propagation. This waves reaches the station first because the P waves travels at a speed, that is much faster in comparison to the S waves. The S waves are the secondary waves and are commonly known as the shear waves.

The P waves have the ability to travel in both solid as well as in liquid, whereas the S waves can propagate only in solid region because they are absorbed at the core-mantle boundary.

Thus, the P waves will arrive the station first and the difference between the arrival of P and S waves are plotted in the graph that helps in depicting the epicenter and the amount of energy released during an earthquake.

Some jellyfish are transparent, how will this affect their ability to survive?

Answers

So predators cannot see it as well

Explanation:

It will affect their ability to survive because...since Jellyfish bodies are transparent, that means they are less visible to predators or threats. Which will affect their way to survive because since they are less visible to predators, it gives them a better chance for survival since their predators can't see them very well. It also gives them a better chance for survival because hunters won't be able to see them well enough to catch them because they blend in with the water, which is called transparent.
