C. The combination of high winds and flood waters.
Hope this helps you! :)
<h2>(D) is the correct option </h2>
Explanation:
- Both the stapedius and tensor tympani are striated muscles
- The stapedius is about 6 mm in length, arises from the pyramidal process and the tendon attaches to the posterior neck of the stapes
- The stapedius is a muscle with a high oxidative capacity
- The tensor tympani is about 25 mm in length, the muscle is not as strong as the stapedius, and the tendon also contains more elastic tissue and fat
- The tensor tympani courses through a bony canal in the wall of the anterior middle ear, and attaches to the neck of the manubrium
- The tensor tympani and stapedius muscles are protective reflexes
- They reduce the amount of sound that gets into the inner ear
- They are somewhat similar to the blink reflex thus they can be triggered by loud noise, and when they go off, both ears can be involved
- If stapedius and tensor tympani muscles is not present then loud sounds would cause the ossicles to move too much, potentially causing damage to the inner ear
Answer:
Neutral, positive or negative
Explanation:
In the nucleus we have protons (with positive charge) and neutrons (without charge). In the outer shell are electrons (negative electrical charge). In the event that the number of protons and electrons are equal, that atom is electrically neutral.
Answer:
C) large cells containing many nuclei
Explanation:
Mitosis (it's a stage in the cell cycle) is seen when the cell DNA has undergo duplication, resulting in two sets of chromosomes in a cell which are separated with the formation of two identical nuclei imside the cell.
We know that normally cytokinesis is the final stage in mitosis resulting in division of the cell cytoplasm and nuclei over two separate, identical daughter cells. ***The aftermath of mitosis without cytokinesis yield a cell with more than one nucleus.***
This type of cell is termed a multinucleated cell. It may occur normally as seen in humans possessing particular multinucleated bone cells (osteoclasts) which are produced via this means. This process can also be seen at the early development of particular insects e.g. the fruit fly (Drosophila). It may be a sign of a altered cell cycle, indicating a pathological activity as observed in tumors.
