Answer:
1.878g
Explanation:
Volume = 30.0ml
Density = 0.626gcm−3
Mass = ?
Be careful in this kind of questions to check for the units. In this case one has to remember 1 mL equal 1 cm³ so density = 0.626g/ml
The relationship between all three parameters is given by the equationn below;
Mass = Density * Volume
Mass = 0.626g/ml * 30 = 1.878g
Explanation:
The basis for classifying changes in matter into physical and chemical change is to see if a material is altered after going through a process.
In a physical change only the state of matter is usually altered especially its form or shape.
Chemical change alters a substance by producing new kinds that are totally different from it.
- In a chemical change, new kinds of matter are usually formed.
- Such changes are usually irreversible.
- Change of state is a reversible process.

<u>Individual lipid molecules are free to diffuse laterally in the surface of the bilayer</u> is a general feature of the lipid bilayer in all biological membranes
Explanation:
The inside of the bilipid layer of the cell membrane of cells is made of fatty acid chains and cholesterol which are nonpolar molecules. they are sandwiched between the polar (glycerol) ends of the chains because they are hydrophobic and cannot interact with the ‘watery’ extracellular fluids. Non-polar molecules like lipids can easily diffuse laterally, within this lipid layers of the membrane because non-polar molecules interact well with other nonpolar molecules.
