Answer:
C) substitutions that reduce the affinity of hemoglobin for oxygen
Explanation:
Heinz bodies are inclusions in the eritrocite, filled by denaturalized globin (protein part of the hemoglobin). Hemoglobin is formed by 4 globin subunits (2 alpha chains and 2 beta chains) plus a heme group. The latter, is responsible for oxygen binding.
The denaturalization of the globin is caused by substitutions that do not allow the protein to fold properly and bind the heme group accordingly. This is the cause of the Heinz bodies in the eritrocite. Therefore, this is a structural problem that impedes the protein to fold into a functional protein and has nothing to do with hemoglobin having less affinity for oxygen. In the last mentioned case, the protein is still functional but poorly binds oxygen, hence, does not for Heinz bodies.
This ratio is approximately a one to one ratio, meaning that a person's arm span is about equal to their height. There are many more human body ratios; some are independent of age, and others change as we grow from a baby to an adult I hope this is correct
Answer:
Rickets disease.
Explanation:
Rickets disease occurs when there is a mineralization deficit of the extracellular bone matrix; as a result, the bones are soft, and they deform easily. The X-rays show thick epiphyseal plates because it is hyaline cartilage that should be calcified to become a bone. As there is a deficit of vitamin D, the mineralization of the plate can not be done, making bone is flexible and deformable.
The main cause for Rickets disease is a diet with low intakes of calcium and vitamin D, and poor exposition to the sun, which is the best way to produce vitamin D. These two components are crucial for the mineralization of the bones.
Cerebrospinal Fluid (CSF) flows through the four ventricles and then flows between the meninges in an area called the subarachnoid space. CSF cushions the brain and spinal cord against forceful blows distributes important substances and carries away waste products.
