Studying evolutionary relationship among organisms
Just take out the fluff.
Plants that are fertilized with fish meal will be healthier for plants than the plants that receive artificial fertilizer.
Or make one of those If, Then, Because statements.
If a plant is fertilized with fish meal rather than artificial fertilizer, then the plants will be overall healthier because fish meal is natural compared to the artificial fertilizer.
In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell.——————Neurotransmitters are endogenous chemicals that enable neurotransmission. It is a type of chemical messenger which transmits signals across a chemical synapse, such as a neuromuscular junction, from one neuron (nerve cell) to another "target" neuron, muscle cell, or gland cell.
A direct observation is usually something that you see with your own eyes
Urm,Is that a question or what,I'm confused.
