Sonja [21]

A fertilized egg developing is called an embryo. You can rule out unfertilized because it implies that the egg contains no developing life form. You can also rule out the fertilized egg as it is mentioned in the question previously.

If there is dissolved carbon dioxide in the water, are underwater plants able to perform photosynthesis? Explain why or why not.

Alenkasestr [34]

Answer:

Plants undergo photosynthesis, which is the process where carbon dioxide, water, and sunlight are transformed into sugar and oxygen. Even though they look different than terrestrial (land) plants, aquatic plants, or plants that live on the water's surface or submerged underwater, also undergo photosynthesis.

if you were to watch an individual neurotransmitter molecule just after it was released what would happen to it

Olenka [21]

Neurotransmitter leaves the presynaptic cell by exocytosis. It is released in the synaptic space, and moves to the postsynaptic membrane to meet its receptor. When binding occurs, it triggers a response in the new cell.

-----------------------------------------

Every neuron forms connections with another cell.

When a presynaptic cell sends information, a neurotransmitter is released.

After the exocytosis event, this chemical substance travels through the synaptic space forward to the other cell. Once there, it binds to its receptors in the postsynaptic membrane.

When the joining occurs, the receptor acquires a channel shape. This change allows the ion transference that will make possible the modification of the action potential.

This binding produces the excitatory postsynaptic potential -depolarization-.

A new action potential initiates in the postsynaptic cell and spreads to the rest of the membrane, depolarizing it.

If the communication between cells needs to stop, the neurotransmitter will be taken out from the synaptic space <em>instead of binding to its receptor. </em>

There are two mechanisms by which the neurotransmitter can be eliminated: by deactivation or reuptake.
