How the inner ear is responsible for feeling dizzy?
Sonja [21]

Answer:

In turn, the brain tells your body how to stay balanced. If you're on a rollercoaster or a boat that's moving up and down, the fluid in your inner ears might take a while to stop moving. This is why you may feel dizzy for a little while even when you stop moving or are on solid ground. Dizziness caused by the inner ear may feel like a whirling or spinning sensation (vertigo), unsteadiness or lightheadedness and it may be constant or intermittent. It may be aggravated by certain head motions or sudden positional changes.

Explanation:

How do you fix dizziness in the inner ear?

1) Sit on the edge of your bed. Turn your head 45 degrees to the right.

2)Quickly lie down on your left side. Stay there for 30 seconds.

3)Quickly move to lie down on the opposite end of your bed. ...

4) Return slowly to sitting and wait a few minutes.

5) Reverse these moves for the right ear.

which of the following individuals is most likely to allow a recessive lethal gene to be kept in a population over several gener
IRINA_888 [86]
The birth and reproduction of Carrier(Heterozygous) organisms, (i.e) heterozygous individuals that have a dominant allele masking the effects of the recessive 'lethal gene.' However even though the gene is masked, it is still there. Therefore, if the heterozygous individual is to reproduce with another heterozygous (carrier) organism there is a higher chance that their offspring will have the active form of the 'lethal gene' causing the death of the offspring.
