1.
True or false?: a theory serves three important functions.
Correct Answer
B. False
Explanation
The statement "a theory serves three important functions" is false. The question is asking whether a theory serves three important functions, which implies that there are three specific functions that a theory is expected to fulfill. However, without any further information or context provided, it is not possible to determine what those three functions are. Therefore, the correct answer is false because the statement is incomplete and lacks specificity.
2.
________ theory is scientific because it is testable and can be rejected if the predictions are not confirmed.
Correct Answer
Falsifiable
Explanation
Falsifiable theory is considered scientific because it can be tested and potentially proven false if the predictions it makes are not supported by evidence. This means that the theory is open to being challenged and revised based on empirical observations. It allows for the possibility of new information or data that may contradict the theory, promoting the advancement of scientific knowledge.
3.
What are ONE, of the two groups of the experimental method?
Correct Answer
B. Correlation
Explanation
Correlation is one of the two groups of the experimental method. In experimental research, correlation refers to the statistical relationship between two variables. It is used to determine if there is a relationship between variables and if changes in one variable are associated with changes in another variable. Correlation does not imply causation, but it helps researchers understand the strength and direction of the relationship between variables.
4.
What are ONE, of the three parts of a neuron?
Correct Answer
D. Axon
Explanation
The axon is one of the three main parts of a neuron, along with the dendrites and the cell body. It is a long, slender projection that carries electrical signals away from the cell body to other neurons, muscles, or glands. The axon plays a crucial role in transmitting information throughout the nervous system, allowing for communication between different cells and facilitating the coordination of various bodily functions.
5.
The ________ acts as a relay station for information flowing into or out of the higher brain centres.
Correct Answer
thalamus
Explanation
The thalamus acts as a relay station for information flowing into or out of the higher brain centers. It receives sensory information from various parts of the body and relays it to the appropriate areas of the cerebral cortex for further processing. Additionally, the thalamus also receives motor signals from the cortex and relays them to the spinal cord, enabling voluntary movements. Overall, the thalamus plays a crucial role in regulating sensory and motor functions by facilitating the flow of information between different brain regions.
6.
Which gland produces sex hormones?
Correct Answer
D. Gonads
Explanation
The gonads, which include the ovaries in females and testes in males, are responsible for producing sex hormones. These hormones, such as estrogen and progesterone in females and testosterone in males, play a crucial role in the development and regulation of sexual characteristics and reproductive functions. The pituitary gland, thyroid gland, adrenal glands, and pancreas also produce hormones, but they are not primarily responsible for sex hormone production.
7.
Sensation is the process by which the sensory information is actively organized and interpreted by the brain.
Correct Answer
B. False
Explanation
Sensation is the process by which sensory information is received and transmitted to the brain, not organized and interpreted by the brain. The brain is responsible for the process of perception, which involves interpreting and making sense of sensory information. Therefore, the statement is false.
8.
________ motivates us to tend to injuries, to restrict activity, and to seek medical help.
Correct Answer
Pain
Explanation
Pain serves as a motivator for us to tend to injuries, restrict activity, and seek medical help. When we experience pain, it signals that something is wrong in our body and needs attention. It prompts us to take action to alleviate the discomfort and prevent further damage. Pain acts as a protective mechanism, guiding us to take care of ourselves and seek the necessary medical assistance for proper treatment and recovery.
