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.

Explanation:Mantle convection currents cause plate movement
Bacteria, archaea, plants, protists, animals, and fungi, can use cellular respiration.
And the main ones that use celluar respiration are autotrophs and heterotrophs.

Answer:
4
Explanation:
According to the question, one box of jello has a mass of 250grams.
The question wants us to find how many boxes of jello would collectively weigh 1kg.
Since the units of weight here are in grams (g) and kilograms (kg), we need to convert to the same unit
1kilogram (kg) is equal to 100 grams (g).
Hence, if 1 box of jello weighs 250g
1000g of jello box will be 1000/250 in number
1000 ÷ 250 = 4.
Hence, 4 boxes of jello will weigh 1000g or 1kg.
