A worm starts wiggling faster because it is more hot

• Phototaxis

• Thermotaxis

• Thermokinesis

• Positive thermotaxis

A pigeon uses its ___________ to sense the Earth's magnetic field.

• Thermoreceptor

• Photoreceptor

• Chemoreceptor

• Magnetoreceptor

A pigeon senses the magnetic field of the Earth and flies towards the North magnetic pole.

• Negative magnetotaxis

• Positive magnetotaxis

• Magnetokinesis

• Positive magnetokinesis

A maggot senses the scent of its food and starts increasing its rate of turning until it ends up at the food by chance.

• Positive chemotaxis

• Negative chemotaxis

• Chemokinesis

• Chemokinesis AND klinokinesis

A weta shuffles deeper into a tunnel until it senses that it is surrounded on all sides by the tunnel.

• Thigmokinesis

• Positive thigmotaxis

• Negative thigmotaxis

• Orthokinesis

A slater senses that it is getting hotter so it starts moving faster in random directions.

• Thermotaxis

• Negative thermotaxis

• Thermokinesis

• Thermokinesis AND orthokinesis

A salmon swims upstream against the direction of current flow to find a mate.

• Negative rheotaxis

• Positive rheotaxis

• Rheokinesis

• Positive chemokinesis

Taxis are movements that are:

• Random/non directional

• Directional

Kinesis are movements that are:

• Directional

• Non directional/random

Orthokinesis is when:

• Animals increase their rate of turning in the hopes they escape bad conditions by chance.

• Animals increase their rate of movement (speed) in the hopes they escape bad conditions by chance.

• Animals increase their rate of turning in a certain direction.

• Animals increase their rate of movement in a certain direction.
