Figure 1 Eye Flower Antenna Tongue 0 1 . 1 Why do bees feed on sugar solution? [1 mark] Tick () one box. For gaseous exchange To obtain energy To provide proteins 3 (03) G/Jun23/8465/2F Do not write outside the box Turn over 8 Bees have a simple nervous system. The bee nervous system has many similar features to the human nervous system. 0 1 . 2 The antenna is a sense organ. The antenna contains specialised cells that detect stimuli. What are cells that detect stimuli called? [1 mark] Tick () one box. Coordinators Effectors Receptors 0 1 . 3 When an antenna of a bee touches sugar solution the bee automatically sticks out its tongue. What type of action is automatic? [1 mark] Tick () one box. A conscious action A delayed action A reflex action Question 1 continues on the next page 4 (04) G/Jun23/8465/2F Do not write outside the box Figure 2 shows the nervous pathway taken when a bee antenna touches sugar solution. Figure 2 X Muscle in tongue Y Antenna Sugar solution 0 1 . 4 What is the gap labelled X? [1 mark] Tick () one box. A gland A synapse An impulse 5 (05) G/Jun23/8465/2F Do not write outside the box Turn over 8 0 1 . 5 What type of neurone is Y? [1 mark] Tick () one box. Motor neurone Relay neurone Sensory neurone Eyes are sense organs that can detect electromagnetic radiation. A bee’s eye can detect ultraviolet radiation. 0 1 . 6 Detecting ultraviolet radiation allows the bee to see the parts of the flower that produce sugar solution. Why is it an advantage for bees to see the parts of the flower that produce sugar solution?
