The correct answer is "neurons".
Neurons are nerve cells which connect to each other using synapses and form neural networks. They exhibit high levels of specialization and are the primary components of the central nervous system.

Myofibrils are contractile fibers which form the striated muscle cells. Sarcomeres are the structural unit of the myofibrils.

How large may an air mass be?
denis23 [38]
Everything has mass. The mass of something never changes. 

Mass is measured using grams.

Air is not that heavy, but it certainly has mass because it takes up space.

For every one liter of air, their is 1.19 grams.

A newly discovered solar system is found 300 billion kilometers from the sun. How many AU does this represent? Show your work.
Aleksandr-060686 [28]

1 kilometer = 6.68 × 10^{-9} (<<<AU is in scientific notation here)

To convert 300 billion kilometer (3,000,000,000 km)  into AU you must multiply the kilometer by the equivalent of 1 km in AU (6.68 × 10^{-9})

3,000,000,000 × (6.68 × 10^{-9}) =  20.04 AU

Hope this helped!

Explain how the release of sodium and chlorine would lead to a loss of water in the intestines
frosja888 [35]

Answer:

Please find the explanation below

Explanation:

Sodium (Na) and Chlorine (Cl) are two electrolytes that play important role in the absorption of water and nutrients in the small intestine. However, as mentioned in the question, the release of sodium and chlorine would lead to a loss of water in the intestines. This is because of the OSMOTIC phenomenon.

Osmosis is the movement of water molecules from a region of high concentration of water/low concentration of solute to a region of low concentration of water/high concentration of solute via a semipermeable membrane. In this case, the Na+ and Cl- ions serve as the solutes, which when released out of the intestine causes the solution in the intestines to be HYPOTONIC compared to the intestinal environment. This causes an OSMOTIC GRADIENT.

This osmotic gradient i.e. difference in concentration provokes osmotic flow of water from the intestines, which has a low solute/high water concentration, to the outside of the intestines, which has a high solute/low water concentration. Hence, water is lost from the intestine because the solute concentration becomes low when sodium and chlorine ions are released.
