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.

A _________ is an organic compound that must be obtained from the diet and is needed to sustain life.

Answers

A Carbohydrate is an organic compound that must be obtained from a balanced diet

Carbohydrates are food nutrients which are also organic compounds which are required for the sustenance of life because they are a very vital source of energy which the body requires for it to function properly and efficiently.

Other organic compounds are Proteins, lipids and Vitamins because they all contain elements of carbon in them. But for the Human body to be active it requires energy and the most important source of energy to the body is Carbohydrate

Hence we can conclude that Carbohydrate is an organic compound that must be obtained from a balanced diet.

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 :)

go keilani

Answers

A protein that speeds up a biological and chemical reaction to build and split any molecule is called an enzyme. They are produced naturally in the body.

The correct answer is:

Option C. have a complementary shape to the substrate.

This can be explained as:

If the active site on the enzyme is occupied by an inhibitor then the substrate will not be able to bind and the reaction will not occur.

Activation energy is the minimum amount of energy needed for the reaction.

If the enzyme is destroyed then no reaction will occur as the active site is present on the enzyme surfaces.

Therefore, the active site should have a complementary shape to the substrate.
