1. How do fossils form?
noname [10]

Explanation:

There is a LOOOONG process for this so here it is;  

First things first.The animal dies. Soft parts of the animal's body, including skin and muscles, start to rot away. Scavengers may come and eat some of the remains.  Before the body disappears completely, it is buried by sediment - usually mud, sand or silt. Often at this point only the bones and teeth remain.  Many more layers of sediment build up on top. This puts a lot of weight and pressure onto the layers below, squashing them. Eventually, they turn into sedimentary rock.  While this is happening, water seeps into the bones and teeth, turning them to stone as it leaves behind minerals.  This process can take thousands or even millions of years.

I hope this answer helped. Thank you!

A large gradient for sodium exists across a cell membrane. Channels are opened and sodium diffuses freely through the channels.
skelet666 [1.2K]

Answer:

Once the sodium channels opens and sodium is allowed to diffuse freely in and out of the cell, this will cause a large change in entropy and enthalpy. Values for both these quantities will increase significantly, however, the change in free energy will be small when we compare the open and closed state of the sodium channel. With regards to the stability of the system, it will reach equilibrium because the concentration of sodium ions is being allowed to diffuse without any regulation.

Hope that answers the question, have a great day!

What is the Hepatic Portal Vein?​
belka [17]

Answer: The hepatic portal vein is one of the most important vein that receives blood from the body and transports it into the liver for filtration and processing. This vein is part of the hepatic portal system that receives all of the blood draining from the abdominal digestive tract, as well as from the pancreas, gallbladder, and spleen.

‘Hepatic’ means of or relating to the liver, therefore the hepatic portal vein is a blood vessel that sends nutrient-rich blood from the gastrointestinal tract and spleen to the liver, but also delivers toxins to the liver that will be chemically modified in the proces of detoxication
