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!

What happens when the chemical bond that holds the third phosphate is broken?

Answers

The chemical bond between the second and third phosphate groups is a high energy bond. When that bond is broken, energy is released, producing ADP (adenosine diphosphate).

The second and third phosphate groups' chemical connection is a high energy bond. ADP is created when that link is disrupted and energy is released (adenosine diphosphate).

What is phosphate bond?

The structural structure of nucleic acids, including DNA and RNA, is composed of the sugar-phosphate backbone.

This molecule's directionality is determined by this backbone, which is made up of alternating sugar and phosphate groups.

Nucleotides make up DNA and RNA, and they are connected to one another in a chain via chemical interactions between their neighboring nucleotides' phosphate groups and sugar bases.

Therefore, The second and third phosphate groups' chemical connection is a high energy bond. ADP is created when that link is disrupted and energy is released (adenosine diphosphate).

Respiration taking place in presence and absence of oxygen has different end products. Aerobic respiration has the end products as carbon dioxide and water, alcohol is the end product of anaerobic respiration.

What is respiration ?

It is the process in which the complex substituents are broken into simpler products in the presence of oxygen and absence of oxygen in  order to produce energy.

In the aerobic respiration processes like glycolysis takes place where the glucose breaks down into 4  molecules of ATP with the consumption of 2 ATP molecules. 1 glyceraldehyde molecule is produced from the glucose that is 2 glyceraldehyde molecules are produced. Total of 4 ATP are produced.

Alcoholic fermentation is the anaerobic respiration that says the anaerobic respiration where the glucose is broken down into alcohol and water. In the anaerobic respiration, excess of alcohol gets broken  down into lactate.

Answers

Not sure what you mean by understanding reflection but i'll do my best.

World War II was one of / if not the biggest tragedy to happen in modern history. It taught the world important lessons about society; that we need to work together and not let our differences enable another global conflict to the degree of WW2. However, history never completely repeats itself and while WW2 was a terrible and unimaginable tragedy, it provided us with information that can help us all in avoiding a future conflict similar in nature. However, how is the author so certain that history doesn't repeat itself? Have we not seen history do such thing. For example, there were vaccination protests all throughout history just like how there is vaccination protest today. So, I am interested in how the author came to his conclusion that WW2 will not inevitably repeat itself.
