PLEASE HELP WITH MY EARTH SPACE SCIENCE QUESTION

Acetylcholine is a chemical that is found between the nerve synapses, or gaps, between nerve cells. When activated, it causes the contraction of skeletal muscles and activates glandular functions in the endocrine system. Think of acetylcholine as a mailperson; residents cannot receive their mail until he or she comes and delivers it to the mailbox. Like mailpersons who deliver the mail and move on to the next house, acetylcholine acts quickly and does not hang around. As a result, acetylcholine is rapidly broken down by another chemical substance called cholinesterase.
Acetylcholine was the first neurotransmitter scientists discovered, as well as the most abundant neurotransmitter in the body. A neurotransmitter is a chemical that is released by a neuron, or nerve cell, that sends a signal to another neuron across a synapse. The neurotransmitter binds to receptors to affect how the signal is received. The purpose of the neurotransmitter is to either amplify or inhibit the signals sent between the neurons.
Acetylcholine plays an important role in the signal of muscle movement, sensation of pain, learning and memory formation, the regulation of the endocrine system and rapid eye movement (REM) sleep cycles.

Vascular plants help maintain the water cycle. Which property of these plants enables them to carry out this function?

Neporo4naja [7]

A.)Well–developed vascular system
Vascular plants help maintain the water cycle. The property of these plants enables them to carry out this function is their well-developed vascular system. These type of plants are more evolved and developed than nonvascular plants because of its specialized characteristics like xylem, which is a tissue that is responsible for its framework and not only that, it is also has a greater mechanism for water transference. Another is phloem, which is responsible for food conduction.
