<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:
A. the heterozygote advantage
Explanation:
Heterozygote advantage is the condition where the heterozygous individual has higher relative fitness than both homozygous dominant and homozygous recessive individual. This means that the heterozygote individual has higher chances of surviving than both the homozygous counterparts. Sickle cell anemia is a recessive inherited disorder in which oxygen carrying hemoglobin has an abnormal structure. Hence, the resultant RBCs are not spherical but have crescent sickle shape. The oxygen carrying capacity of such RBCs is drastically reduced but they are unaffected by malarial parasite due to their abnormal structure.
- A person with both the recessive genes for sickle cell would not be able to survive due to insufficient oxygen transport in body.
- A person with both the dominant genes would be free of sickle cell anemia but in case of malaria would not be able to survive as the normal RBCs would be hijacked by the parasite.
- A hetrerozygote would survive both in malaria and sickle cell condition since he has enough normal RBCs for oxygen transport but also has sickle cell RBCs which are unaffected by malarial parasite.
Answer:
The answer to the enunciated: your employer lets you know that the safety data sheets are located on a computer in his office. Does this comply with employer responsibilities? is:- This act doesn't comply with the responsibilities of the employer.
Explanation:
The responsibilities of the employer are to guide the employed about the things in the company, of the sentence you can deduct two sceneries:
- The employed is in training in the company, the reason why the employer is saying to him where are the safety data sheets, but the correct would be to show the sheets and how function them.
- The safety data sheets are reserved for people with a high rank in the company, the reason why the employer must not say it to the employed.
I believe the answer you are looking for is Silicon
