We are going to use the ideal gas law. First, convert 475 kPa to Pa because the ideal gas law uses SI units. This will be 475,000 Pa. 
Rearranging the ideal gas law, we get P1V1/T1 = P2V2/T2. Now plug everything in and solve for P2: (475,000)(4)/(290) = (P2)(6.5)/(277)

Name and describe the 5 characteristics of Neuroplasticity
Basile [38]

Answer:

In the word neuroplasticity, the prefix, neuro-, refers to the brain. The suffix, plasticity, refers to malleability or the ability to change. Thus, neuroplasticity refers to the ability of the brain to change. It's important to note that until the mid-20th century it was believed that after childhood the human brain was unchangeable and couldn't respond to external circumstances. However, it's now known that the brain continues to change throughout life.
