Hope this helps!

I accidentally gave the guy on top of me a bad rating but it's actually correct. Sorry dude :[
Ans.
Lipid bilayer is made up of two layers of phospholipids, which show polar, hydrophilic (polar) phosphate groups on surface of cell membrane and non-polar, hydrophobic (non-polar) tails on inner sides. The hydrophobic nature of cell membrane allows transport of small, hydrophobic molecules more quickly than larger, hydrophilic molecules.
Thus, 'the non-polar, uncharged or small molecules, such as water, oxygen and other gases, will diffuse across the lipid membrane most quickly, while the polar, charged or large molecules, such as ions, proteins, and salts, will diffuse most slowly.'
Electricity is caused by moving particles that have either a negative or postivite charge
Explanation:
no statements, an exosystem can thrive on its own with animals and plants that keep it going animals die and go into the ground plants absorb them and grow, fish keep drinking water clean and animals also eat them, carnivores eat the animals and thrive, the sun feeds the plants. herbivores eat the plants and omnivores eat bugs
