Bones are made up of Calcium Phosphate given by the chemical formula, 
. When bones are kept in Hydrochloric acid, given by the chemical formula, HCl, they become soft because the calcium compound present in the bones changes its form. The following double displacement reaction takes place when the bones are kept in HCl,
---> 
Calcium chloride is water soluble, and gets washed away. This makes the bone thin and soft.
Eat foods that are high in fiber. Fiber helps stimulates the muscles in your small intestine that help you digest food better. Probiotic foods like yogurt as well as fresh fruits and vegetables also help carry beneficial bacteria to your small intestine to help prevent the accumulation and growth of harmful bacteria.
Answer:
The correct answer is B. Worms move through changes in body structure caused by contraction of muscles compressing their watery fluid.
Explanation:
The hydroskeleton consists of a fluid-filled cavity, surrounded by muscles. The fluid pressure and the action of the muscles that border it, serve to change the body's shape and produce a movement such as digging or swimming. The successive contraction of various metamers, which are provided with bundles of circular and longitudinal muscle fibers, stretching and thickening parts of the body, allow it to move horizontally. Hydrostatic skeletons have a role in the locomotion of annelids, nematodes and other invertebrates. The hydroskeleton has similarities with the hydrostatic muscles.
When the cell gains glucose, the process of glycolysis occurs and then the glucose is broken down into pyruvate.
Now, in pyruvate processing, Acetyl CoA is produced and used in the Krebs Cycle.
During that process, NADH and FADH2 are made and go into the electron transport chain. That is where water and ATP are made.
