Exitatory neurotrasmitter excite the postsynaptic memebrane by increasing the action potential effects. They <u>allow</u> the messages passage from one cell to the other.
<h3>
What do excitatory neurotransmitters cause?</h3>
Neurotransmitters might be either excitatory or inhibitory.
As the term suggests, excitatory neurotransmitters are in charge of exciting the postsynaptic cell.
Once the neurotransmitter is released from the presynaptic membrane, it travels through the synaptic space until it reaches the postsynaptic membrane.
When the molecule meets its receptor, it triggers a series of events that excite the receiving neuron increasing the action potential effects and <u>allowing </u>messages to be passed from one cell to the other.

Macroevolution can cause significant changes in the frequencies of alleles, that can ultimately result in speciation (forming of new species).
Various large-scale events like climate change and continental drift can greatly influence the distribution of species and adaptive radiation of different groups that can fill vacant ecological niches.
The changes in gene regulation and genetic mutations can also contribute to macroevolution by producing novel traits and adaptations.
Answer:
This is false. They alter their generations by giving birth to newborn plants. they do not alter their generations by switching between phases.
Explanation:
Answer:
Plant cells are eukaryotic cells, that are found in green plants, photosynthetic eukaryotes of the kingdom Plantae which means they have a membrane-bound nucleus. They have a variety of membrane-bound cell organelles that perform various specific functions to maintain the normal functioning of the plant cell.
Answer:
(look at explanation)
Explanation:
The central nervous system CNS is responsible for integrating sensory information and responding accordingly. It consists of two main components: The spinal cord serves as a conduit for signals between the brain and the rest of the body. It also controls simple musculoskeletal reflexes without input from the brain.
