Which cells in the immune system produce antibodies?
Answer: B lymphocytes (plasma cells)
B lymphocytes differentiate into plasma cells, which are specialized for producing and secreting antibodies.
What is the function of the epiglottis in vertebrates?
Answer: Preventing food from entering the trachea
The epiglottis is a flap of cartilage that covers the trachea during swallowing to prevent food from entering the airway.
In the vertebrate nervous system, which type of neuron carries signals FROM sensory receptors TO the central nervous system?
Answer: Afferent (sensory) neurons
Afferent neurons transmit sensory information from peripheral receptors to the spinal cord and brain.
Which hormone lowers blood glucose by promoting cellular uptake of glucose?
Answer: Insulin
Insulin, secreted by beta cells of the pancreatic islets, facilitates glucose uptake by cells, lowering blood sugar.
What is the primary role of the lymphatic system?
Answer: Returning interstitial fluid to the bloodstream and supporting immunity
The lymphatic system drains excess interstitial fluid back into the blood and is central to immune surveillance and response.
Which structure connects a muscle to a bone in the vertebrate musculoskeletal system?
Answer: Tendon
Tendons are tough bands of fibrous connective tissue that attach skeletal muscles to bones.
In the vertebrate eye, where are photoreceptors (rods and cones) located?
Answer: Retina
Rods and cones are photoreceptor cells found in the retina, the light-sensitive layer at the back of the eye.
