Your answer is burning gasoline. if you think about it, none of the rest of the answers really involve chemicals. ice isnt known as a chemical, and so isnt glass. and if your dent a bumper, it doesnt make sense to add it as a chemical change. so your answer is burning gasoline. hope this helps.
Sedimentary rocks form when new sediments are deposited on top of older rock
answer is the first1 off spring to parants
Explanation:
Lipids are composed of fatty acids which form the hydrobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which id water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backbone) with up to 36 carbons.
Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.
Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers or at as doorways for other molecules to pass through. Cholesterol, which is comparatively rigid, anchors other molecules attached to the membrane, maintain membrane stability or structural integrity and aid in separating some lipids, helping with membrane fluidity at low environmental temperatures.
Remember, essential features:
- lipid bilayer
- cholesterols
- proteins (cell markers and doorways)

They use mutualism, echo-location to communicate.
It is a unique social interactions that are used by spinner dolphins and pilot whales. They spin as a social interaction, they start to hunt.
It is the mutualism, because create a bait ball of the fish they want to eat.
The spinner Dolphins ( Stenella longirostris ) commonly use inshore island and atoll habitats for daytime rest and social interactions and forage over deep waters at night. In Hawaii, they occur throughout the archipelago.
The pilot whales are in fact one of the largest members of the dolphin family, but they are treated as whales for the Marine Mammals Protection Regulations 1992. Although they are named pilot whales because it was thought that each pod followed a 'pilot' in the group.
