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: diaphragm
Explanation:
The diaphragm separates the thoracic cavity from the abdominal and pelvic cavity.
The diaphragm is a sheet of internal skeletal muscle located below the thoracic cavity that houses the heart and lungs. Below the diaphragm is the abdominal cavity.
The diaphragm plays an essential function for respiration. When the diaphragm contracts, the volume of the thoracic cavity increases so that air is drawn into the lungs.
Answer:
C
Explanation:
Height in humans is influenced by numerous loci and has a relatively smooth distribution. It is thus a quantitative or continuous trait.
A quantitative trait locus (QTL) is a DNA territory correlated with a specific phenotypic trait that differs in extent and can be linked to polygenic effects, i.e. the product of two or more genes, and their habitat.
<span>This would require an MRI. By using the magnetic waves, the doctor can figure out which tissues in the brain sustained damage (if any). In addition, the MRI can produce images that would not be as easily shown by CT scans.</span>
The food web would be likely destroyed because one animal will not have nothing to eat out of the food we’d and then that’s how the food web will be messed up
