Sound waves travel through gas liquid and solids A) True B) False

Novay_Z [31]

Answer:

True.

Explanation:

Sound is a form of Energy that produces a sensation of hearing in our ears.
Sound is produced as a result of vibration produced in a body.
Sound energy is transmitted from one place o other place by wave motion.
When a body vibrates, the particles of medium surrounding it starts vibrating about their mean position.
During vibration, they collide with the surrounding particle and transfer some energy to them.
They then start vibrating faster and transferring energy to the next surrounding particle. This process continues till the vibration reaches a person ear.
Thus, particles are an important factor in propagation of sound.
Sound cannot travel in vacuum.
It requires a medium to travel from one point to another.
A sound can travel in all medium, solids, liquids and gases as all of these have particles.
The speed of sound is highest in solids and lowest in gases as the inter molecular space is largest in gases and smallest in solids.

When comparing animal to plant cells, they are different in size, shape, and how they store energy. They have similarities, as w

fgiga [73]

Answer:

ribosome, cell membrane, nucleus

Explanation:

The organelles that perform similar functions in both plant and animal cells among the listed organelles would be the ribosome, the cell membrane, and the nucleus.

First of all, chloroplast and cell wall are limited to the plant cell only. Animal cells do not have these organelles.

The ribosome functions as the site of protein synthesis in both plant and animal cells. The cell membrane acts as a channel for the control of the movement of materials in and out of the cells and is found in both plant and animal cells. The nucleus is also present in both cells and serves as the control unit of the cell by housing the genetic materials and dictating how the cells will behave.
