Tay-Sachs destroys nerve cells in the brain & spinal cord. Pku is a birth defect that causes amino acids to build up in the body. They are similar because you can get seizures from both & in both there is also slow growth.
Answer: B.
Explanation: Cytokinesis is the last stage of mitosis. In cytokinesis, the cytoplasm and the membranes divide to create two separate cells.
You can remember this because both cytokinesis and cytoplasm start with "cyto".
Answer:
Both have two circuits for circulation.
Explanation:
- The two circuits of circulations are known as the systemic circuit and the pulmonary circuit.
- In the<u> systemic circuit</u> oxygenated blood from the heart is pumped to all parts of the body through the blood vessels and then the blood is pumped back to he heart.
- In the<u> pulmonary circuit</u> deoxygenated blood from all parts of the body is pumped from the heart to the lungs to be oxygenated and after it is oxygenated it is pumped back to the heart.
Answer: Insulin Growth factor 1 (IGF-1)or Somatomedin C.
This is a <u>peptide hormone produced in the liver with a profound effects on growth at childhood stage. </u> Its secretion begins <u>slowly at infancy</u>, reaches<u> peak at puberty,</u> where it <u>influences growth sprout and remains at the plateau at old old age</u>. This secretion is stimulated by the <u>Growth hormone</u>.GH
However, its secretion is inhibited, by malnutrition, absence of Growth hormones receptors, non-response to Growth hormones stimulation; and blood concentration levels varies with insulin levels, types of nutrition, exercise and age.
Elevated Levels
Growth hormones is release into the blood stream from the pituitary gland.This is followed by its stimulation of synthesis of IGF-1 by the liver. <u>This hormone in-turn promotes the growth of the body systems which occurred by promoting the growth of cells of the body of certain organs especially; of the skeletal muscles, bones kidney, liver etc. </u>
The elevation of blood levels of GH, leads to corresponding over-stimulation of the liver to produce IGF-1. This leads to increase in system growth of body cells through rapid growth of general body cells.and thereforeT growth sprout.
