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!
D. Heterotrophs EXPLANATION: Heterotrophs cannot produce its own food so it kills and eats other organisms for energy. Plants are autotrophs which means they can make their own foods.
1. what clue to the presence of certain genetic disorders can be seen in karyotype? 2. why might a lab worker attempting to diagnose a genetic disorder prefer to work with photographs of chromosomes rather than the chromosome themselves? 3.why would it be much difficult to construct a karyotype of unstained chromosomes?
