Answer: Neurotransmitter
Explanation:
Neurotransmitter are refers to as chemical messengers, which are secreted by the nerves cells, to stimulate neighbouring neuron, thereby allowing impulses to be passed from one cell to next, throughout the entire nervous system. Neurotransmitter are released by the axon terminal, after an action potential has reached the synapse, which the is the neuron transmit signal. Neurotransmitter are often released when, electric signal gets to neuron, it triggers the vesicles that contains neurotransmitters, which will split neurotransmitters into the synapse.

Answer:
Nile crocodile
Explanation:
The Egyptian plover is a small bird with a very unusual friend in the animal kingdom. This bird actually has a symbiotic relationship with the Nile crocodile. It may seem very odd relationship, but it is one that works excellently for both sides. The crocodiles have sharp set of teeth, but they have spaces between them and can not move their jaws sideways. Because of this, very often there's meat stuck between the teeth of the crocodiles, and this is when the Egyptian plover comes on the scene. This little bird actually gets into the open mouth of the crocodiles, picking up the pieces of meat that have stuck between their teeth, and then continuing with its mission. The crocodiles do not try to eat this bird, but instead they stand still while it does its job. The relationship is beneficial for both sides, as the crocodiles have their own personal ''dentist'', while the plover gets free food.
Answer:
A mitochondrion is a double-membrane-bound organelle found in most eukaryotic organisms. Mitochondria generate most of the cell's supply of adenosine triphosphate, used as a source of chemical energy. They were first discovered by Albert von Kölliker in 1880 in the voluntary muscles of insects.
