Answer- FALSE
Fetal benzodiazepine syndrome is a condition of infants
which is caused by the use of benzodiazepine by the mother during pregnancy. Children
with this syndrome often present with malformed face, delayed mental
development and learning disabilities, poor coordination, poor muscle tone, and
tremors.
I believe the answer is 1) Obtain Energy
You can classify them according to the way they get their food because if they eat plants, then they are herbivores. If animals eat herbivores, then they are consumers. Etc.
Answer:
hemoglobin will bind more oxygen when the partial pressure is low than when the partial pressure is high.
Explanation:
Binding of hemoglobin to oxygen is regulated by several factors. However, the partial pressure of oxygen is the most important factor that determines how much oxygen will bind to hemoglobin. When the partial pressure of O2 is high, hemoglobin binds with large amounts of O2. On the other hand, when the partial pressure of O2 is low, hemoglobin is only partially saturated.
Therefore, the greater the partial pressure of oxygen, the more O2 will bind to hemoglobin until saturation is reached. This is why a lot of O2 binds to hemoglobin in pulmonary capillaries where the partial pressure of oxygen is high.
<h2>CNS </h2>
Explanation:
An example of a myelin producing cell in the CNS is oligodendrocyte
- The major function of oligodendrocytes is the formation of myelin
- Myelin acts as an insulator of axonal segments and is a prerequisite for the high velocity of nerve conduction
- Larger axons form thicker myelin
- During development, oligodendrocytes arise from precursors located in the sub-ventricular zone such as the sub-ventricular zone of the lateral ventricles for the cerebrum or the fourth ventricle for the cerebellum
- In the spinal cord, oligodendrocytes originate from the ventral regions of the neural tube and in the optic nerve they migrate into the nerve from the third ventricle
- It is the oligodendrocyte precursor cells which migrate to their destination where they then differentiate into the more mature oligodendrocytes
- The proliferation of the oligodendrocyte progenitor cells is controlled by a number of growth factors released predominantly from neurons but also from astrocytes such as platelet derived growth factor (PDGF) or fibroblast growth factor (FGF)
