The poison placed by natives of the Amazon rainforest on the tips of darts affect the muscle cells of the prey. Therefore, the correct statement is option A.
What are the functions of muscle cells?The poison placed by natives of the Amazon rainforest on the tips of darts affect the muscle cells of the prey. Muscle cells are responsible for the movement, i.e., contracting and relaxing. The poison also paralyze muscle cells of the prey, which causes them to be unable to move.
Poison can interfere with the muscle cells of prey. The poison can bind to the receptors on the surface of the muscle cells, thereby, blocking the neurotransmitters responsible for sending signals to the muscles to contract.
The poison can also interfere with the cellular processes responsible for generating the energy without which, the muscle cells are not be able to contract. Poison have a direct impact on the ability to move, making the prey easier to capture.
Therefore, the poison affect the muscle cells of prey.
