Question 1: Does the regulation of blood glucose levels involve processes that amplify changes to restore balance?
A. Ano
B. Ne
Explanation: Negative feedback reverses changes to restore balance, and the regulation of blood glucose is given as an example of negative feedback.
Question 2: The primary functions of the nervous system include processing information and coordinating responses, but it does not detect stimuli.
A. Ano
B. Ne
Explanation: The nervous system functions by detecting stimuli, processing information, and coordinating responses. Therefore, it does detect stimuli, in addition to its other roles.
Question 3: Sensory neurons are the type of neurons that transport information directly to the Central Nervous System.
A. Ano
B. Ne
Explanation: Sensory neurons are defined as carrying information to the Central Nervous System according to the provided study materials.
Question 4: The primary function of a synapse is to allow neurons to directly transmit electrical signals to each other through physical contact.
A. Ano
B. Ne
Explanation: A synapse is the connection between neurons, but the study materials state that neurotransmitters carry signals across the synaptic gap, not through direct physical contact and electrical transmission at the gap itself. They allow communication between nerve cells via chemical messengers.
Question 5: Estrogen causes breast development during puberty.
A. Ano
B. Ne
Explanation: During puberty, estrogen in girls is responsible for breast development, wider hips, and the regulation of the menstrual cycle.
