Answers

Answer 1
1. The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane.
2. The sound waves move through each of these mediums by vibrating the molecules in the matter.
Answer 2

Explanation:

1. The middle ear is an air-filled cavity that turns sound waves into vibrations and delivers them to the inner ear. Sounds hit the eardrum, making it move. This movement leads to vibrations of three very small bones in the middle ear known as the ossicles

2. Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly. Liquids are not packed as tightly.

how is it when your heart stops beatting

Answers

When your heart stops beating you might die or pass out

Answer:

death occurs if it stops for too long

Explanation:

Cardiac arrest is the sudden loss of cardiac function, when the heart abruptly stops beating. Unless resuscitative efforts are begun immediately, cardiac arrest leads to death within a few minutes. This is often referred to by doctors as "sudden death" or "sudden cardiac death (SCD)."

According to Dr. Sam Parnia, death is defined as the time when the heart has stopped beating. The blood from the heart then fails to reach the brain to sustain it. This means all the reflexes of the base of the brain including “gag reflex” or “pupil reflex in the eyes” are all lost almost instantaneously.

what part of the brain controls your movement and balance

Answers

Answer:

The cerebrum

Explanation:

Deep down in your brain, there's an area called the substantia nigra, which is in the basal ganglia. Some of its cells make dopamine, a chemical that carries messages around your brain. When you need to scratch an itch or kick a ball, dopamine quickly carries a message to the nerve cell that controls that movement.

The cerebrum controls voluntary movement, speech, intelligence, memory, emotion, and sensory processing. At the base of the brain, the brain stem connects to the spinal cord and is made up of the midbrain, pons, and medulla oblongata.
