Answer:
The structure that is in physical contact with the auditory receptor stereocilia is the tectorial membrane.
Explanation:
The tectorial membrane is a structure or a thin layer of tissue that is floating in the endolymph on the stereocilia of the ciliated cells. Ciliated cells, which are sensory cells attached to the surface of the basilar membrane.
When the ciliated cells move up and down, microscopic projections similar to sows (known as stereocilia), which are located above the ciliated cells, cause the cilia to lean towards the side wall of the cochlea. This inclination makes that some channels that look like pores open, which are at the tips of the stereocilia. When this happens, certain chemicals enter the cells, thus generating an electrical signal. The inner ciliated cell is activated, probably by a direct contact of its stereocilia with the Hensen band of the tectorial membrane, the synapse between the ciliated cell and the auditory nerve fibers, send a message to the brain, which converts it into sounds that we can recognize and understand.
The labelled diagram is attached below & the correct sequence is shown below:
4. Sun Heat - The heat of sun causes water to evaporate.
2. Evaporation- vaporization of water
6. Condensation - The conversion of water vapours from gaseous to liquid state.
1. Precipitation - water falls from clouds in the form of rain, snow or sleet.
5. Run off - The surface water is a major part of the collected water, flows from top of any surface (form rain, snow etc)
3. Collection of water - The rain water is collected.
Answer:
<u>A common element among all the river valley civilizations was irrigation systems that moved water to crops and settlements</u>
Explanation:
- <u>River Valley civilizations where the civilizations that were found on the banks of the river like the Mesopotamia ,Indus valley civilization.</u>
- <u>These civilization where agriculture based civilization as they depended on river for drinking water and irrigational activities</u>
<span>Answer: Bone marrow stem cells have been shown to generate cartilage, bone, and muscle when injected directly into the injured site
Stem cells could differentiate into the various type of cells, makes them able to regenerate part of the body that doesn't have regeneration abilities. The cell that involved the </span><span>tear of the rotator cuff would be cartilage, bone, and muscle. Stem cells could replace the damaged cells so that the muscle and joint might work better. </span>
