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.

Which of the following characteristics can distinguish bacterial cells from cells in the other domains of life

SVETLANKA909090 [29]

The characteristic that can distinguish bacterial cells from cells in the other domains of life is that only bacterial cells have peptidoglycan cell wells.

What is the major difference between a bacterial cell and the cells of other organisms?

Animal and plant cells are different from bacterial cells in a number of ways. One key distinction is that, unlike plant and animal cells, bacterial cells lack internal organelles including mitochondria, chloroplasts, and a nucleus.

Bacteria can be categorised according to their morphology, such as bacilli (rod-shaped), cocci (sphere-shaped), and spirilli (spirals). In that they have cytoplasm, ribosomes, and a plasma membrane, bacteria resemble eukaryotic cells. A bacterial cell can be distinguished from a eukaryotic cell by its circular nucleoid DNA, absence of membrane-bound organelles, peptidoglycan cell wall, and flagella.

vaieri [72.5K]

Answer:

Neuroscientists conducted research with taxicab drivers in London and found that taxicab drivers, who are required to have a tremendous amount of spatial and geographic knowledge, had a larger hippocampus than other drivers.

Option D.hippocampus

Explanation:

Hippocampus is concerned with following important functions:

Storage of new information in the memory (converting short memories into long memories)
Comparing sensory information with what the brain expects about the world

Enabling us to form spatial memories for investigating the environment

As the geographic knowledge and spatial knowledge is being stored in the hippocampus, the taxi driver surely have greater hippocampus than other drivers.
