Answer: High Frequency waves by method of compression bone conduction
Explanation: in this, vibration of the bones of the skull and sometimes, arguably soft tissues leads to the production of sounds. The outer and middle ear is bypassed in this method of sound production. Sound reaches the inner ear directly and its a process largely involved in designing hearing aids.
Answer:
b. brings the postsynaptic cell to the chloride equilibrium potential
Explanation:
Gamma-aminobutyric acid (GABA) is one of the most important neurotransmitters, chemicals that brain cells use to communicate with each other. In fact, it is the most frequent inhibitory neurotransmitter. Inhibiting neurotransmitters decrease the chances that a nerve impulse will be triggered.
The main function of GABA as an inhibitory neurotransmitter is to slow down brain activity. It is also involved in vision, sleep, muscle tone and motor control.
It is widely distributed both inside and outside the central nervous system. It is found in the intestines, stomach, bladder, lungs, liver, skin, spleen, muscles, kidneys, pancreas and reproductive organs.
In vertebrates, GABA leads the postsynaptic cell to the chloride equilibrium potential. Through it, chloride ions flow out of the cell to achieve equilibrium.
The planet is neptune wind currents operate in much wider bands around the planet allowing storm like great dark spots to slowly drift across latitudes.
Answer:
Lung
Explanation:
Lungs expand to pull oxygen into the body and contract to push it back out. The larynx is known as the voice box which is an air way passage to the lungs and a pharanx is membrane lined cavity behind the nose and mouth. Neither of these really expand or contact during inhalation so the answer is Lungs.
Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water.
