A peptide bond is a chemical bondformed between two molecules whenthe carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
Answer:
Q1: C. salinity Q2: density Q3: B. densest, least dense Q4: C. closest to the surface
Explanation:
Q1: The term "salinity" refers to the concentrations of salts in water or soils. Q2: when the amount of salt in the water increase which usually gathers mostly at the shallow top of the ocean which is where the warm shallow water gathers, when the warm water has enough salt in it, it sinks to a deeper location causing its density to heighten and that's also what makes it cold. Q3: When layers form in the ocean, the water containing the most dissolved salt tends to form the bottom layer. The water having the least amount of salt is usually on top, because it is the least dense. As more solids are dissolved in water, the water becomes more dense. Q4: Cold water has a higher density than warm water. Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface. I really need brainliest please do so.
1. The bottle left in the sun is exposed to the thermal energy which causes it to heat up. Ice is cold and the bottle is in direct contact with the ice.
2. Its harder for cold winds to get through to you when theres 3 or even 4 layers of clothing on your body than one thick one.
3. Common Sense?... the rug is thick and the tile is... a tile
