Answer: A . Has its collagen fibers randomly orientated.
Explanation:
In the microscopic anatomy of the bone, an osteon (basic microscope unit of the bone) can be arranged into two categories; woven bone or lamellar bone.
As the name suggests woven bone is characterized by the random orientation of the collagen fibers . These collagen fibers haphazardly form to give the visual appearance of an intertwined (woven) network of collagen fibers.
Due to the randomness of the collagen fibers orientation woven bone is thus mechanically weaker than lamellar bone. Woven bone is formed/produced when osteoblasts produce osteoids rapidly within the bone matrix thus woven bone has the ability to form quickly as needed.
Woven bone is thus immature bone or pathologic bone with no stress orientation, it has a high percentage of osteocytes per unit volume and a high rate of turnover.
Answer:
Embryonic stem cells could be used to make more specialized tissues that have been lost to disease and injury. For tissues that are constantly replaced, like blood and skin, stem cells would probably be replaced directly.
Explanation:
The main function of the flower stock is transporting food in the form of water and nutrients to different parts of the plant with the help of xylem and phloem. Xylem helps in transporting cells that help in carrying water and minerals from the roots while phloem transports food in the form of sugar to all parts of the plant. The stock also helps in keeping the the flower steady above the plant folliage. This directly helps in the process of pollination of the plant. The flower that is held steady above the folliage attracts bees and other insects through which it continues the process of pollination.
Since it is a organism, we know its a living thing.
Ex: Rock=not living=not organism
Plant=Living=Organism
If you studied it under a microsope, you would expect to see cells as every living thing has. A microscope is a tool used by scientist and are made to see very little things that our regular eyes and a magnifying glass cannot see. So you would see cells because cells are very very tiny
