Answer:
The correct answer is: Cerebellum
Explanation:
Cerebellum is a part of the hindbrain and is found in the posterior cranial fossa in the cranial cavity.
This part of the brain receives inputs from the spinal cord and the brain and thus plays a crucial role in <u>motor control</u>. It is associated with <u>timing, coordination, and precision.</u>
It is also involved in the regulation of fear and pleasure responses, attention and language.
<u>Since in the given example, after the accident Tracey is experiencing difficulty in coordination. Therefore, she has most likely damaged the </u><u>Cerebellum</u><u>.</u>
Answer:
The research cannot be classified as a true experiment because the researcher didn't control the participants of each group.
Explanation:
To have more control over the variables, the researcher must also control the assignment of the participants that will be in each group. The intention is that both the experimental and the control group have very similar conditions in order to observe the relationship between the dependent and the independent variable.
Answer:
The correct answer is B: The phosphorus-starved plant was unable to synthesize both the required nucleic acids and lipids, limiting growth.
Explanation:
Phosphorus is a vital component in plants because it is present in the RNA and DNA of plants, elements that helps in the storage of information on how certain functions should be performed by plants. These functions include protein synthesis, sugar metabolism, and lipids and nucleic acid synthesis. Thus in the absence of phosphorus, growth will be limited because lipids and nucleic acid would not be synthesized.
ANSWER: RELATED TO TASK DIFFICULTY.
EXPLANATION:
Psychologically, OPTIMAL AROUSAL refers to the level of mental stimulation which results to full maximization of learning process, physical performance (such as seen in athletes) or proper wellbeing.
However, research has established that different levels of arousal is generated for different tasks to get optimal performance. It was also established by researchers of this context that lower or optimal level of arousal is generated for difficult tasks to ensue better concentration. In the other hand, tasks with less intellectual demands generates higher levels of arousal in other to increase motivation.
We can say that the most important contribution of Edward Thorndike is the formulation of the so-called law of effect, from the studies he did with cats in problem boxes from which they had to escape. The law of effect will explain Skinner's theory of operant conditioning.
According to Thorndike, learning is made up of a series of connections between a stimulus and a response, which are strengthened each time they generate a satisfactory state of affairs for the organism. This theory provided the basis upon which Burrhus Frederic Skinner then built his entire building on operant conditioning.
