Answer:
Hyperpolarization means that the membrane potential becomes more negative than the resting potential.
Explanation:
The voltage across the membrane of a neuron that is at rest and not sending out signals is called the resting membrane potential, or just the resting potential. The concentration gradients of ions across the membrane and the amount of each type of ion that can pass through the membrane determine the resting potential. When a neuron is at rest, there are different levels of sodium and potassium on both sides of the cell membrane. Ions move down their gradients through channels. This creates a difference in charge, which gives rise to the resting potential.
When the membrane potential at a particular location on the neuron's membrane gets more negative, this phenomenon is known as hyperpolarization. Depolarization, on the other hand, occurs when the membrane potential becomes less negative (more positive). Both depolarization and hyperpolarization can take place as a result of the opening and closing of ion channels in the membrane, which changes the rate at which certain types of ions can enter or leave the cell.

<h3><u>Answer;</u></h3>
Compressions
Rarefactions
<h3><u>Explanations;</u></h3>
- A wave is a transmission of a disturbance from one point to another, and involve the transfer of energy from the source to another point.
- Waves may be classified as longitudinal waves or transverse wave depending on the vibration of particles relative to the wave motion or mechanical and electromagnetic waves based on the material medium of transmission.
- <em><u>Sound waves are examples of longitudinal waves that are mechanical waves since they require material medium for transmission. Longitudinal waves involves transmission of waves such that the vibration of particles is parallel to the wave motion , creating compressions and rarefactions.</u></em>
Pericardium in the Medical report from Ms. K means fibrous tissue surrounding the heart. The pericardium is the membrane that is enclosing the heart, consisting of an outer fibrous layer and an inner double layer of serous membrane. It is a membrane that surrounds and protects the human heart. It is also a double-walled sac containing the heart and the roots of the vessels. The Pericardial sac has a serious layer and a fibrous layer, total of two layers. This pericardial sac encloses the pericardial cavity which contains pericardial fluid. Pericardium also has a disorders namely Pericarditis, Pericardial effusion, and Cardiac Tamponade.
A hypothesis is a testable possible explanation, while a theory is an explanation that has been tested extensively.
