Imagine yourself in a dark classroom reading PowerPoint slides. If an audience member were to check the internet using her cell

phone and causing her screen to light up, chances are that many people would notice the change in illumination in the classroom. However, if the same thing happened in a brightly lit classroom during a discussion, very few people would notice. The cell phone brightness does not change, but its ability to be detected as a change in illumination varies dramatically between the two contexts. This is an example of ________.

The answer is Weber's law

Answer:

Weber's Law

Explanation:

Weber-Fechner's Law relates the physical magnitude of a stimulus to the subjective intensity of a person's sensation. It goes for any sensory perception, be it auditory, visual, thermal, tactile, taste or olfactory. Generally speaking, the Weber-Fechner Law can be stated as follows: the increase in stimulus necessary to produce the minimum increase in sensation is proportional to the pre-existing stimulus. Cell phone light is a stimulus, which is increased in low light situations, so this light is more noticeable in a dark and quiet room than in a room with lots of people talking.

Question 12 of 20 :
daser333 [38]
A; Carbon’s atomic number is 6, atomic number indicates the amount of protons in an atom. The number of protons (positively charged particles) is equal to the number of electrons (negatively charged particles). Because atoms have a neutral charge. The average atomic mass of carbon is 12.011; this is the amount of protons plus the amount of neutrons because electrons are so small they weigh almost nothing compared to protons and neutrons. To find the number of neutrons you subtract the number of protons from the average atomic mass. 12.011-6=6.011 (which can just be rounded to 6). So a carbon atom has 6 neutrons. Answer A is correct because it correctly states that an atom of carbon has 6 protons 6 neutrons and 6 electrons

Imagine taking a bite of a pizza. Briefly discuss the role that each part of the brain takes in this simple act. Medulla, Pons,
Anon25 [30]

Answer:

- Medulla: transmits signals between the spinal cord and higher brain levels

- Pons: transmits impulses related to the voluntary skeletal movements from the cerebrum to the cerebellum

- Cerebellum: coordinates skeletal muscle contraction, conscious/subconscious movements, maintains muscle posture, and balance

- Thalamus: regulation of the human nervous system

- Hypothalamus: maintains the overall homeostasis of the body

- Amygdala: processes fearful and threatening stimuli  

- Hippocampus: regulates learning, memory encoding and consolidation, and spatial navigation

- Parietal Lobe: processes information from the outside world (e.g., touch, taste, temperature)

- Occipital Lobe: interprets information from the eyes

- Temporal Lobes:  process sensory information (i.e., pain and auditory stimuli)

- Frontal Lobe:  higher cognitive functions (e.g., memory, problem-solving, emotions, impulse control, etc)

Explanation:

The medulla (medulla oblongata) is the lowest portion of the brainstem, which is linked by the pons to the midbrain and continues with the spinal cord. The medulla is known to transmit signals between the spinal cord and higher brain levels, thereby controlling autonomic activities (e.g., heartbeat and respiration). The pons is a mass of transverse nerve fibers that links the medulla with the cerebellum, it transmits signals from the forebrain to the cerebellum. The pons is involved in different functions, e.g., sleep, respiration, hearing, equilibrium, taste, eye movement, swallowing, bladder regulation, facial expression, etc. The cerebellum is a small part of the brain involved in physical movements (e.g., posture, balance, coordination), which receives sensory information from sensory systems, the spinal cord, and different parts of the brain. The cerebrum is the largest part of the brain, it is involved in speech, thinking, reasoning, problem-solving, emotions, initiating/coordinating movements, regulating temperature, learning, etc. The thalamus is a mass of gray matter located in the forebrain which is involved in diverse functions (i.e., relay of sensory signals, regulation of consciousness, sleep, alertness, etc). The hypothalamus is a small, central, area of the brain that connects the nervous to the endocrine system that acts to maintain the overall homeostasis of the body. The amygdala is a structure located in each hemisphere of the brain that processes fearful and threatening stimuli. The hippocampus is a structure located in the depths of the temporal lobe that regulates learning, memory encoding and consolidation, and spatial navigation. The parietal lobe is located at the upper back area in the skull, it is involved in processing sensory information from the surrounding world (e.g., touch, taste, temperature). The occipital lobes are responsible for transmitting visual information to the temporal lobes, and they are also associated with memory skills. The frontal lobe is the most anterior part of the brain, which is involved in higher cognitive functions (e.g., social interaction, motor function, memory, emotions, impulse control, problem-solving, etc).
