Answer:
Option (D). 
Explanation:
ATP (adenotriphosphate) molecules are considered as energy currency of the cells as molecules provide energy for various cellular functions. 
The energy is stored in ATPs in two high-energy phosphate bonds, known as phosphoanhydride bonds. This stored energy is released in during hydrolysis of ATP, which involves removal of terminal phosphate groups bound the carbon backbone. 
Thus, the correct answer is option (D). 
 
        
                    
             
        
        
        
<u>Answer:</u>
Q: Which skeletal system <u>disorder</u> might she be suffering from? 
A: <u>Osteoporosis</u>
Q: What <u>techniques</u> could be used to diagnose her condition? 
A: <u>Bone mineral density (BMD) test</u> or <u>dual energy X-ray absorptiometry (DXA) scan</u>
Q: What treatments are available?
A: Medication, healthy food.
<u>Explanation:</u>
<u>The vertebral discs between vertebrae could shrink with age</u>. Therefore, a height loss up to 1-inch is normal. However, if the height loss is more then it is possibly due to <u>osteoporosis</u>.
A <u>bone mineral density test</u>, also known as <u>dual energy X-ray absorptiometry</u> scan, is a well-adapted test to measure the amount of calcium and other minerals in the bones. It uses <u>X-rays</u> to measure the content of calcium and thus strength of bones.
A person who is already suffering from osteoporosis should be treated with <u>medicine</u> right away so that it <u>stops</u> further <u>deterioration of the bones</u> and <u>avoid any future bone fractures</u>. Further, it can be handled by <u>eating a healthy diet</u> and <u>supplements</u> such as <u>vitamins D</u>. In case some of the bones/vertebrae are <u>already fractured</u>, <u>surgical approaches</u> might be necessary.
 
        
             
        
        
        
Answer:
The difference is:
a) Positive feedback increases a change while negative feedback reduces a change.
b) Positive feedback occurs specific situations while negative feedback occurs in the body.
c) Positive feedback break down the homeostasis while negative feedback maintain the conditions of homeostasis.
d) Positive feedback has less frequent mechanism while negative feedback has more frequent mechanism.
e) Positive feedback enhances change while negative feedback resists change.
f) Positive feedback has a wider range while negative feedback has a narrow range.
