The water hyacinth is an invasive species that can spread extremely fast, blanketing a water surface in a very short period of t
miss Akunina [59]

Answer:

how changes in biodiversity impact an ecosystem

Explanation:

Water hyacinth is a free-floating perennial aquatic plant. This plant is native to tropical and sub-tropical South America. As an invasive species, when it grows in the new environment causes severe ecological or economic harm. By growing where it not native, it can spread extremely fast, blanketing a water surface in a very short period of time. It can limit boat traffic, swimming, and fishing, and it can deprive native plants and animals of sunlight and oxygen, thus reducing the local biodiversity.

This is how an ecosystem effects biodiversity impact. When a biological species grows in the new environment, It can affect the biodiversity or environment that can affect the biological species.

How do the diffuse modulatory and point-to-point synaptic communication systems in the brain differ? list four ways?
Vesna [10]

Diffuse modulatory synapses or neuromodulation function different than simple point-to point synapses.

1. Number of postsynaptic neurons

In neuromodulation neuron uses one or more neurotransmitter to regulate several neurons. In Synaptic point-to-point transmission only one particular neuron receives signal from the presynaptic neuron.

2. Neurotransmitter sin neuromodulation (neuromodulators) are not reabsorbed broken down by the pre-synaptic neuron like those in classic synapse. Neuromodulators stay in cerebrospinal fluid.

3. Receptors are also different: the receptors for the neuromodulators are typically G-protein coupled receptors while in classical chemical neurotransmission, they are ligand-gated ion channels.

4. Neuromodulation is a slow process, while classic synaptic transmission occurs fast.
