Answer:
Is composed of trabeculae that are oriented along lines of stress. (Ans. D)
Explanation:
Spongy bones are also known as trabecular and cancellous bones. It is covered by compact bones and present in the long bones. They are known as spongy because they are highly vascular and porous tissues.
Osteoblast thin area creating the turbeculae space between the tissues. Spongy bones are also known for home of hematopoietic stem cells and bone marrow, which are helping to differentiate white blood cells, red blood cells, and platelets.
Some difference between spongy bone and compact bone are:
1) Spongy bones are light weight and compact bones are heavy.
2) Spongy bones are composed of trabeculae and compact bones are composed of osteons.
3) Spongy bones are known as cancellous and compact bones are known as cortical bones.

Answer:
B. The trypsin produced by the reaction is capable of splitting and activating additional trypsinogen molecules.
Explanation:
Positive feedback mechanisms trigger a chain of events to intensify change from an original condition. Trypsin is secreted in an inactive form called trypsinogen. As trypsinogen reaches the lumen of the small intestine, enterokinase serves as an activating brush-border enzyme. Enterokinase splits off trypsinogen molecule to form trypsin. The activated trypsin protein molecules further activate additional trypsinogen into trypsin. Therefore, it represents how a positive feedback mechanism intensifies the original stimulus.
