Answer:
Vesicles
Explanation:
Serotonin is a neurotransmitter that transports signals or messages between neurons.
Most neuronal cells have vesicles in their interior, which are organelles that store neurotransmitters for exportation -by exocytosis- or from recycling -by endocytosis-. These vesicles also protect the neurotransmitter from the enzymatic action.
Vesicles form in the cellular soma, from where they are transported to nervous terminals. Once the vesicle releases the neurotransmitter to the intercellular space, their membrane remains available in the plasmatic membrane to be reused.
The neurotransmitter concentration in the vesicle interior is related to the storage system and the <u>transport system</u>. There are <u>specialized transporter proteins in the vesicle membrane</u> that are involved with the introduction of the molecule to the organelle.
In the exposed example, transporter Trans B might be located in the vesicle membranes, and hence could be found in the cytosol of the cells.
Answer:
The gene that encodes ampicillin resistance.
Explanation:
The plasmid would contain the ampicillin resistance gene which gets expressed in the presence of ampicillin.
All types of Active transport require ATP:
-Active transport
-Endocytosis
-Exocytosis
Answer:
The correct answer to this question would be 196.9 million miles squared.
Explanation:
The Earth's surface area is equal to 196.9 million mi^2. That is A LOT. I hope this helps :)
I would say the answer is A. moistens and filters incoming air.
