Answer:
The correct order of events in sound transmission is 1, 4, 2,3 5
Explanation:
1. Tympanic membrane vibrates.
4. Ossicles of the ear vibrate.
2. Internal ear fluids are set in motion.
3. Hearing receptors are stimulated.
5. Auditory cortex is stimulated.
Sound is received by external ear or pinna that travels into the ear canal and causes the eardrum or tympanic membrane to move. The tympanic membrane vibrates with sound waves. Sound vibrations move through the ear bones or ossicles to the cochlea and cochlea moves due to sound vibration. Fluid movement causes the hair cells to move. As hair cells move up and down, electrical signals is generated. The auditory nerve sends electrical signal to the brain, which turns it into a sound.
Answer 1: The skin and the Liver are easy to repair using stem cells.
Explanation:
Method of stem cells to heal liver disorders has been demonstrated useful in most of the situations. Scientific research shows the use of stem cells in the therapy and remedy of several disorders like Liver Cirrhosis, End Stage Liver Failure, hereditary liver disorder and including the Liver tumor. The stem cells hold the capacity to regenerate and reproduce by them or stem cells hold particular properties of renewing themselves. Because of their expertise stem cells can modify into any tissue sort, they have enormous potential in several infection treatments and traumatic damages.
Answer 2: Apical meristem and the lateral.The heart, brain, bone marrow and the Lungs in adults are difficult to repair using stem cells.
Explanation:
There are two kinds of stem cells: embryonic stem cells and adult stem cells. Adults also have stem cells in the heart, brain, bone marrow, lungs, and other organs. They are our built-in replacement tools, restoring cells infected by infection, trauma and everyday erosion, and cut. Adult stem cells are extremely difficult for specialists to operate because they are extra challenging to derive and culture than their immature complements.
