When the head is tilted, what are the structures the signal passes through on its way to becoming a fully processed neural signa
Ann [662]

Answer:

The fluid within the semicircular ducts of the inner ear, that is, endolymph moves when the head is tilted. The precise position of the stimulated cells relies upon the plane of movement with each vertical or horizontal plane being signified by distinct parts of its composition. The hair cells that transduce the signal into an electrical signal get stimulated due to the movement of fluid. The conduction of this signal takes place via the auditory nerve to the cochlear nucleus of the brainstem.

Within the inner ear cochlea, the stimulation of the hair cells or stereocilia takes place by endolymph, it is a fluid present in semicircular ducts. After stimulation, the hair cells mediate electric signals to the brain via the auditory nerve, these are the nerve bundles that carry signals of sound. The initial central auditory composition found in the brainstem is the Cochlea nucleus.

Talja [164]

Answer:

1) IV: The quantity of salt added

DV: The resultant density of the salinated water

Hypothesis: The egg will float when the  mass of the volume of the salinated solution displaced by the egg is equal to or larger than the mass of the egg

2) IV: The extension of the rubber band above original length in centimetres

DV: The distance flown by the rubber band

Hypothesis: The potential energy stored in the rubber band by pulling will be transformed into kinetic energy and the larger the extension, the larger the stored potential energy, and the larger the resultant kinetic energy, the higher the velocity and the further the distance flown

3) IV: The wing span of a paper airplane

DV: The distance flown by the plane

Hypothesis; The glide of the airplane is a factor of the wings span increased wingspan increased glide and increased travel distance

4) IV: Presence of more light

DV: Height to which plant grows

Hypothesis: Photosynthesis, which is the conversion of carbon dioxide and water into glucose and oxygen in the presence of Sunlight is essential for plant growth and the more the presence on light is increases the higher plant will tend to grow

5) IV: Amount of vinegar in the canister

DV: The height a rocket will launch

Hypothesis: With a given amount of baking soda, in the canister a little amount of vinegar causes a delayed launch but an increased build up of carbon dioxide resulting in higher height reached than when more vinegar is used in which case the lift off will be more rapid but the power will be lesser and the height reached reduced

6: IV: Surface area of the coin

DV: The number of drops held

Hypothesis: Due to surface tension and cohesion which are properties that increase with surface area and as such a coin with a larger surface area holds more water drops

7. IV: Number of hours of study

DV: Science score

Hypothesis: A student science scores is directly related to the amount of science topics thought the student is able to respond to in a test and it is directly proportional to the amount of study the student has done  related to the science topics
