(PLEASE HELP ASAP) (WILL GIVE BRAINLIEST AND THANKS) As an airplane rises through the atmosphere, machines cause the pressure in

side the cabin to decrease. As the airplane descends toward Earth, machines cause the pressure inside the cabin to increase. Based on your observations from the Can Crush Lab, explain why these changes in pressure are necessary.

Well, from what I know..
In high elevations, there are fewer air molecules above a given surface than a similar surface at lower levels. Most of the atmospheres molecules are held close to the earth's surface by the force of gravity and hence air pressure decreases rapidly at first, then more slowly at higher levels.
Sooooo if the pressure in an airplane cabin isn't changed, it can cause injury or harm to passengers and oxygen equipment is required above 8,000 altitude.

In ________ conditioning, an established conditioned stimulus is paired with a new neutral stimulus.
irina [24]

An established conditioned stimulus is paired with a new neutral stimulus in: higher-order conditioning.

Classical conditioning refer to a learning process that involves the repeated pairing of two (2) stimuli:

  • Conditioned stimulus.
  • Unconditioned stimulus.

Basically, classical conditioning is a learning procedure which helps psychologists in understanding when a neutral stimulus is paired with a conditioned response or a neutral stimulus and an unconditional stimulus.

Similarly, a higher-order conditioning involves pairing an established conditioned stimulus with a new neutral (the second-order) stimulus, in order to make the new stimulus elicit (bring forth) the conditioned response, without presenting the initial conditioned stimulus.

Answer:

<em>The correct option would be option 3) organism 1 and 3 will be more closely related than organisms 2 and 4.</em>

Explanation:

Depending on the physical characteristics only, we can see that the organisms shown in number 1 and in number 3 are similar o one another but not purely identical. This means that these organism are closely related to one another.

The organisms shown in option 2 and 4 are not very similar to one another depending on the physical characteristics. Hence, we can say that organisms shown in number 1 and number 3 are more closely related to one another s compared to the organism shown in option 2 and 4.
