No, molecules come in various sizes. The size of a molecule is determined by the number and arrangement of its atoms. Small molecules like oxygen and water are much simpler and smaller than complex molecules like proteins and DNA.
The size of the membrane pores depend on the proteins constituting the pore, thus different proteins may cause different pore sizes. So in most cases, yes, the "pores" will most likely be of different sizes.
These terms refer to different sizes of telecommunication groups that are used to categorize the number of channels within a system. Group typically refers to a small number of channels, Super group is a larger grouping of groups, Master group is an even larger grouping of super groups, and Jumbo group is the largest, encompassing multiple master groups.
They are more metabolically acitve then larger cells because they have a smaller surface area to volume ratio then the larger cells which means the enzymes and proteins can move around faster and this makes the cell metabolically active.
The factors affecting London forces are the size of the atoms or molecules involved (larger sizes result in stronger forces), the shape of the atoms or molecules (more surface area allows for stronger forces), and the polarizability of the atoms or molecules (more easily distorted electron clouds lead to stronger forces).
because of molecules
A molecule is a group of atoms that are chemically bound together. There are many different atoms such as "H" for Hydrogen or "He" for Helium or "Na" for Sodium. Scientists represent these atoms in different sizes and colours.
Only if it is of the same material. In other cases, it may, or may not, have less molecules. Molecules come in many different sizes (or masses).
molecules in water are all different sizes and don't really have a arrange meant
BCI group size ( 65 )
They selectively allow certain size molecules to enter, or not to enter, the cell.
Lack of active transport. Diffusion rates sets size limits.
Products offered by Arcadia Group are fashion items. Arcadia Group offers a wide range of clothing in many styles, sizes, and colors. Arcadia Group has stores worldwide.
stratified sample
Reduce portion sizes, and eat few carbohydrates. Not to mention get active!
Polar molecules such as glucose, salts, and amino acids interact well with water molecules due to their ability to form hydrogen bonds. Additionally, some nonpolar molecules with small sizes, like ethanol and acetone, can also interact with water through weak van der Waals forces.
No, molecules come in various sizes. The size of a molecule is determined by the number and arrangement of its atoms. Small molecules like oxygen and water are much simpler and smaller than complex molecules like proteins and DNA.
