<h2>THE DIGESTIVE SYSTEM</h2>

Title:
<h2>A SUGAR MOLECULES LIFE </h2>
1st entry
- Hello, there! I'm a sugar molecule who lives in a miniature chocolate Debbie Cake! I've just lived a brief life, and today is the day I delve into the unknown, the human body's interior. I'm quite apprehensive! As the ravenous teenager rips the plastic wrapper from my body, I experience a mixture of thrill and dread as I'm brought to his mouth, readied for mechanical digestion, and immediately transfixed by the boy's keen teeth. As a thick substance called saliva tears me apart into minute molecules, I begin to feel the incredible amount of anguish coursing through my body. This must be the "chemical digestion" I'd heard about! I degrade when the boy swallows me.
2nd entry
- I can feel the heart sphincter loosen as I pass through it. I'm waiting...and then the stomach secretes hydrochloric acid into the esophagus, creating the teenager's acid reflux! Now I'm in a muddle with hydrochloric acid, pepsin, and mucus generated by the stomach wall glands.
3rd entry
- I'm now slipping through the body at a breakneck speed! The small intestine appears to be visible! It's like a gigantic slide, with such a small opening, yet I'll slide right in!
4th entry
- Simply floating here and riding through the water and other fluids released by the stomach, such as hydrochloric acid, pepsin, and mucus, or chyme, which is soupy food that used to be solids.
5th entry
- I'm absorbed into the lining of the small intestine by the capillaries, and I know I've accomplished my goal! I can see the light now.
6th entry
- In the small intestine, the coolness is still present. I'm not sure I'll go to the big intestine; it appears that it's only for water and water-soluble vitamins. Whoa! I'm glad to see all of my sugar molecule pals here! We've all started clumping together and forming a solid!
7th entry
- Isn't it possible that we're about to leave? There isn't much water or drink in this place! But we're being pushed! We're on our way down! I notice an opening and believe we're about to leave the body!
Answer:
1.25 µm
Explanation:
The cell will have a length dimension that is 1/40000 times the length of the image:
(50·10^-3 m)/(40·10^3) = 1.25·10^-6 m = 1.25 µm
I think the first one is right !.... but the for the other one it's B .
The statement is true. Atelectasis is the collapse or closure of a lung resulting in reduced or absent gas exchange. It may effect part or all of a lung. An airway blockage also can cause Atelectasis. A blockage may be due to a foreign object, a mucus plug, lung cancer, or a poorly placed breathing tube from a ventilator. When a blockage occurs, the air that's already in the air sacs is absorbed into the bloodstream.
Because atoms are conserved in a reaction and atoms are the building blocks of matter thus is it said that matter is conserved.
for your own knowledge .... a few other things are conserved
mass
momentum
energy
charge
