Flatworms (apart from the turbellarians, (planarians are in the class turbellaria)) are parasitic and don't need complex nervous systems. A parasitic animal devotes much of itself to reproduction and doesn't worry about other tasks. Cestodes don't even have a gut, they absorb food via diffusion through their skin. Annelids are free-living animals, and they need to move around more. They don't spend their adult life hooked to the inside of an animal, they move around, and need a more complex nervous system to give them a better view of their world.

Write a scientific explanation to describe the impact of the infected papaya trees on the toucan population.
seraphim [82]

The infected papaya trees will produce less carbohydrates or chemical energy for the toucan. If there were fewer carbohydrates within each papaya, the toucan's muscle cells would not be able to obtain as much chemical energy as they normally do. This chemical energy will be converted into mechanical energy or heat flow, which the toucan uses to fly.

Therefore, the lower amount of mechanical energy and heat flow from the muscle contractions, it would result into a reduced amount of kinetic energy of motion when the toucan is flying.

What manages muscles and prevents injury by monitoring the rate of muscle contraction?
IgorLugansk [536]

Golgi tendon organ manages muscles and prevents injury by monitoring the rate of muscle contraction.

What is the Golgi tendon organ? What is its primary function?

Sensory organs called Golgi tendon organs (GTOs) are found in the tendon next to the myotendinous junction. The Golgi tendon organ, which is located close to the point where a tendon joins a muscle, is a sensory ending that resembles a tree and is encased in a spindle-shaped connective tissue capsule.

The Golgi tendon organ is the sensory organ that determines how much tension the muscle is exerting when someone lifts weights. The Golgi tendon organ will prevent the muscle from producing any force (by a reflex arc) if there is excessive muscle tension, preventing you from harming yourself. Together, these monitor muscle length via the muscle spindles.
