Answer:
I'm pretty sure it's A. yes they do
Blood cells carry oxygen to the rest of the cells in the body, and hemoglobin can help it do so. But in order for the hemoglobin to be effective enough, the blood cell has to be a certain kind of shape.
<span>Keep in mind that muscle cells don't carry oxygen and that they have different structure which helps in flexing and moving around only. </span>
<span>Human genetic disorders can be caused largely by the change of the DNA sequence from its normal sequence. This can also be caused by a monogenic disorder, a mutation in a gene. So the best answer to this question would be letter B since nondisjunction causes chromosomal abnormalities.</span>
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.
