Answer:

Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Which best blocks X-ray particles and can therefore be observed more closely through the use of this technology?
Vedmedyk [2.9K]

Answer:

The correct answer would be bones.

X-rays are high energy electromagnetic waves which have an ability to penetrate most of the biological tissues.

In the X-ray machine, a beam of high energy X-rays is passed through the filters and subject and then fall on the detector or photographic film to produce X-ray.

Dense tissues like bone, teeth, tumors et cetera blocks or stops most of the X-ray particles from reaching the detector or photographic film.

It forms glowing pictures on the X-ray film or photographic film.

The denser the material the brighter the image will be formed on the photographic film.

When egg white is heated, it hardens and is opaque. This cooking process cannot be reversed, but hard-boiled egg white can be di
marshall27 [118]

Answer:

Generally proteins are denatured at high temperature.Therefore when  the egg is hard boiled they are denatured since eggs are protein,  the 3-dimensional  structure of protein is lost, and it is replaces with tangled meshwork of polypeptide chains .This is because the  orderly arrangements of  disulphide bonds in proteins  are disrupted , which  results in the formation of inter chains bonds among   disulphide bonds, making the protein molecules to link together.This explains the reason for the 3-D structure disruption  and formation of  a macro molecule.

However,   the  addition of reducing agent ,  breaks the covalent disulphide bonds.   While detergent breaks the interchain bonds among the disulphide bonds.  (The noncovalent bonds),These combined effects untangled the  mesh networks of polypeptides formed, and reduces the hardened nature,

3.Why is the surface of the Earth in constant motion?
tekilochka [14]
3. It's because of the heat underneath the crust of the Earth. Because heat rises, the molten rock and such underneath the crust rises to the top and then the movement underneath causes things on top to move. 

4. Plates are the different sections that the lithosphere has been cracked into. These plates once all fit together as a giant plate called Pangaea. 

5.  An earthquake is a sudden, sometimes violent shaking of the ground, as a result of the shifting of tectonic plates, or volcanic eruption. 

6. On the magnitude scale, earthquakes range from 2.5 or less (usually never felt but strong enough to be detected by seismograph) to 8.0 or higher. Causes extreme damage; enough to destroy whole cities at once if close enough to the epicenter. 

7. Depends on what kind you're looking for. I'd look it up for your specific topic.

8. To apply a forces to something, usually resulting in a stretch.

9.  The action of compressing something, to flatten or squeeze by pressure

10. A strain on the layers of something because of pressure, resulting in the shifting of those layers.

11. In areas undergoing extension or stretching. It's when the crust is extended. 

12.  The hanging wall drops relative to the footwall. 

13. This is what happens when the hanging wall <u>rises</u> relative to the footwall. (The opposite of a normal fault)
