Answer:
Spongy bone is well adapted to accept stress in many directions, which makes it good for shock absorption
Explanation:
Spongy bone tissue is less compact and always present towards the interior of the bone and is covered by compact bone. Spongy bone tissue has lamellae that are arranged in an irregular pattern. The thin irregular columns of lamellae are called trabeculae.
The trabeculae of spongy bone tissues are precisely arranged along the line of stress. This feature of spongy bones allows them to resist the stress applied from many directions and to transfer the force making them a good shock absorber. The final arrangement of trabeculae is achieved only after the person learns the locomotory movements completely.
Answer:D. Water has a neutral pH.
Explanation:
The answer is 4Fe+3O2→2Fe2O3
Answer: C. The red blood cells released water through osmosis. The release of water helped the blood cells keep a similar concentration of solutes as the outside solution.
Explanation:
Osmosis is a process whereby water molecules move from an area where they are in higher concentration than a solute to an area where they are in lower concentration. They do this by moving through a selectively-permeable membrane.
With sugar added to the solution, the water in the red blood cells will have a higher concentration of water in the cells than the solution so water molecules will move from the cell - through the cell membrane - to the solution. They will keep doing so till the concentration of solutes are more or less similar in both the cells and the solution.
