A solution is a chemical reaction?

Biology
1 answer:
MaRussiya [10]3 years ago
4 0

Answer:

False

Explanation:

A solution does not have to be a chemical reaction.  Salt and water is a perfect example.  Even though salt will dissolve in water, there is no chemical reaction going on.  Salt remains salt and water remains water.  The salt can easily be recovered by evaporating off the water.

Some solutions can be a chemical reactions but not all have to be.

kherson [118]

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.

Plz help due now As children age, how do their psychological and physical abilities change?
ArbitrLikvidat [17]

Answer:

The various stages of development in children are reached at a unique time and rate for every child. But there are a number of common key categories to consider when looking at your child’s early health and development. Explanation:

In infancy, toddlerhood, and early childhood, the body’s physical development is rapid (Figure 1). On average, newborns weigh between 5 and 10 pounds, and a newborn’s weight typically doubles in six months and triples in one year. By 2 years old the weight will have quadrupled, so we can expect that a 2 year old should weigh between 20 and 40 pounds.

HOPE THIS HELPS :)
