Sean enjoys studying the stars. He used a photometry tool to calculate several stars' apparent magnitudes (how bright a star loo

ks in the sky). He then researched the stars' distances from Earth. He recorded his results in the table below.

If you increase the number of water molecules in the extracellular fluid, will the membrane move to the right or the left in the
Igoryamba

Answer:

The membrane will move to the left in view of the applied pressure.

Explanation:

The scenario described can be perfectly illustrated through understanding the concept of osmosis.

Osmosis can be defined as the movement of particules or molecules in a solvent from a region of lower concentration to a region of higher concentration, through a semi permeable membrane.

To put differently, the movement of water molecules is from a region of lower osmotic pressure to a higher one. And for osmosis to be achieved and water molecules evenly distributed, pressure built must be slow and steady to a state of high or equilibrium.

This often results to movement of membrane to the left as a response to the osmosis phenomenon. Increasing the number of water molecules in the extra cellular fluid will thus accelerate this process, increase the pressure built up, and thus generate ripples from a lower area to a higher one. Osmosis is thus gradual and steady.

Organic molecules are sometimes found within meteorites that crash into Earth. Which meteorite condition in space is similar to
nevsk [136]

The presence of inorganic molecules is the meteorite condition in space similar to what was likely present in Earth's early atmosphere.  

The earth initial atmosphere in its early form was too reducing and it was made up entirely of gases such as carbon monoxide, ammonia, methane, nitrogen and other gases.

This atmosphere did not have free oxygen, since it was the result of the mixture of metals, hydrogen and other chemical elements.

The high temperatures, ultraviolet rays and electrical discharges in the early atmosphere would have caused chemical reactions of the elements to form primitive organic molecules.

Meteorites are fragments of solid matter that contain a record of the chemical substances that existed in the early Solar System.

The most predominant gases still found in the space are hydrogen and helium.

Therefore, we can conclude that hydrogen and the presence of inorganic molecules are the initial elements that make up the Earth's early atmosphere and that they are conditions that are present in the space and so in the formation of meteorites.
