∙ 9y agoIn a condensation reaction two molecules are covalently bound and water (H2O) is generated. As a rule, one molecule releases an -OH and one gives up a -H in the reaction.

∙ 9y agoYes, removing the -H and -OH ends can allow the molecules to fit together more easily by reducing steric hindrance and promoting favorable intermolecular interactions. This can lead to closer packing and better alignment of the molecules in the solid state.
Molecular solids are soft and easily compressible because the molecules in these solids are held together by weak intermolecular forces. These forces allow the molecules to move past each other easily when pressure is applied, leading to compression. The lack of strong bonds between the molecules also contributes to the softness of the solid.
A fine mesh strainer or a slotted spoon would be useful for removing peas from the canning liquid, as they allow you to separate the peas from the liquid easily while keeping the peas intact.
The plasma membrane is provided with very small passages to allow the molecules of water and ions of other elements. It is made up of lipo-proteins and has semipermeability.
Solids have a fixed shape and volume due to their tightly packed arrangement of atoms or molecules. When a force is applied to stretch a solid, the intermolecular forces opposing the deformation are too strong to allow the atoms or molecules to move apart easily, preventing the solid from being stretched.
In a liquid, molecules are relatively close together but still have the freedom to move past one another. The intermolecular forces between molecules are strong enough to keep them together but not rigidly fixed in place like in a solid. These properties allow liquids to flow and take the shape of their container.
Hydrophobic molecules are permeable to the cell membrane. Anything that is samll and hydrophobic will pass easily. Larger, hydrophilic molecules require a transport protein to allow permeability.
The lipid bilayer is made up of nonpolar hydrophobic tails that repel polar molecules, making it difficult for them to pass through. Polar molecules are also unable to dissolve in the hydrophobic environment of the lipid bilayer, further hindering their diffusion across the membrane. This selective barrier allows the cell to control the movement of polar molecules in and out of the cell.
Nuclear pores are large protein complexes that regulate the passage of molecules into and out of the cell's nucleus. They control the movement of molecules such as proteins, RNA, and other signaling molecules based on their size and specific signals.
catabolic molecules
it is a semi-permeable membrane that will allow small molecules to pass through it. its function is to control what passes through and also to hold the cells together

Ammonia gas liquefies when it is exposed to high pressure and low temperature. By increasing the pressure and decreasing the temperature, the ammonia gas molecules come closer together, reducing their kinetic energy and causing them to form a liquid state.
