Answer:
Diffraction
Explanation:
Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible.
Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.
hope this helps :)

The organs represented in the image are the Brain, nerve, and spinal cords that monitor and react to changes in the body and its environment.
<h3>What are Organs?</h3>
Organs may be defined as an assemblage of tissues that structurally construct an operational unit specialized to accomplish a distinct operation and functions in the body of a living organism.
The nerves function in sending and receiving signals to the brain from external stimuli. They give the perception of feeling pain, relaxation, stress, etc to the brain according to the situations.
The complete question is as follows:
The picture shows an organ system in the human body.
Brain, Nerve, and spinal cord.
What do these organs do in the human body?
- They filter pathogens and dead cells out of lymph before it returns to the blood.
- They monitor and react to changes in the body and its environment.
- They release hormones that control the activities of cells and organs.
- They identify and destroy things that are foreign or harmful to the body.
Therefore, the correct option for this question is B, i.e. They monitor and react to changes in the body and its environment.
