PADI OPEN WATER Final Exam A with 100% Correct Answers 2024 Pdf 1. If an object is neutrally buoyant (does not sink or float) in fresh water; the same object placed into salt water would Answer sink. 2. Imagine you blow up a balloon, tie it off, and take it to the bottom of the swimming pool. What will happen to the balloon and the air inside it Answer The balloon will get smaller and the air inside the balloon will be more dense (molecules move closer together). 3. Imagine you turn a glass...

transport proteins - are responsible for controlling passage across the membrane fluid mosaic model - The membrane is a mosaic of protein molecules bobbing in a fluid bilayer of phospholipids fatty acid tails - nonpolar, hydrophobic fatty acid heads - hydrophilic, polar periphial proteins - bound to the surface of the membrane integral proteins - penetrate the hydrophobic core (ones that span the membrane are transmembrane protiens How do cells recognize each other? - by binding to molec...

1) If an object is neutrally buoyant (does not sink or float) in fresh water, the same object placed into salt water would A sink. B either sink or float. C do nothing. D float. - D 2) I blow up a balloon, tie it off, and take it to the bottom of the swimming pool. What will happen to the balloon and the air inside it? A The balloon will get bigger and the air inside the balloon will be less dense (molecules move further apart). B The balloon will get smaller and the air inside the balloon wi...

1) If an object is neutrally buoyant (does not sink or float) in fresh water, the same object placed into salt water would A sink. B either sink or float. C do nothing. D float. D float. Salt water is heavier than fresh water because it has dissolved minerals in it. This means it causes more upward force (buoyancy) on an object. An object that is neutrally buoyant in fresh water would float in salt water because there is greater upward force. See Being a Diver I - Buoyancy and Control...

why are membranes called phospholipid bilayers? - Answer-phospholipids have hydrophilic head and hydrophobic tail, hydrophobic face inside of cell making 2 layers what is meant by fluid mosaic? - Answer-Mosaic of proteins drifting laterally in fluid bilayer of phospholipids how are membranes adjusted for different temperatures? - Answer-membrane fluidity adjusted by changing the ratio of unsaturated to saturated fatty acids how do the relative amounts of saturated and unsaturated fats chan...
