Answer:

   v = 4.0 10⁴ Hz

Explanation:

The bat emits sound in the air, so we can use the speed of sound in air

          v = 344 m / s

also the expression that relates the wavelength and frequency with the speed of the wave

          v = λ f

          f = v / λ

let's calculate

          v = 344/0.0085

          v = 4.0 10⁴ Hz

Explain how the information from the stimuli is communicated to the brain.
irakobra [83]

Answer:

Answer:Neurons communicate through an electrochemical process. Sensory receptors interact with stimuli such as light, sound, temperature, and pain which is transformed into a code that is carried to the brain by a chain of neurons. Then systems of neurons in the brain interpret this information.

Rosalind Franklin, James Watson, and Francis Crick’s discovered the DNA's Double Helix.

<h3>What is DNA?</h3>

DNA is an abbreviation for deoxyribonucleic acid and it can be defined as the molecules that are found within cells, and they are saddled with the responsibility of storing genetic information in living organisms.

In 1953, James Watson and Francis Crick's used other scientists' work to create a model of DNA in that they used Rosalind Franklin's photo to help them determine that deoxyribonucleic acid (DNA) was a double helix.

Furthermore, the discovery of DNA's Double Helix by Rosalind Franklin, James Watson, and Francis Crick led to modern molecular biology, which has helped many scientists and researcher to understand how genes control the chemical processes in the body of a living organism.
