Ionic bond 4. Hydrogen bond Which of the following is the best explanation for why vegetable oils are liquid at room temperature? A. Vegetable oils have saturated fatty acid tails that do not pack together efficiently and therefore have a low melting point. B. Vegetable oils have saturated fatty acid tails that pack together very efficiently and therefore have a low melting point. C.

Explain why ‘life’ is an emergent property. New properties that arise with each step upward in the hierarchy of life, the complexity increases At which biological level can it ‘emerge?’ It can emerge at a single celled organism A) Atom B) Organelle C) Biomolecule D) Cell E) Organism 1) Can you speculate why more mosquitoes were found near pregnant women than near non-pregnant women? The vector mosquitoes are more likely to take a blood meal from pregnant women than non pregnant 2) At which level of biological organization does malaria spread? Organism 3) At which level of biological organization do malarial symptoms occur? At the organism level

· How do water molecules interact? o Hydrogen bonds · How do water molecules interact with ionic compounds o When a solute dissolves in an aqueous solution (water), the bonds are broken between the ions and the differing charged particles attract different parts of the water molecule § i.e. the positively charged Na molecule attracts the negative oxygen atom in the water molecules · How do water molecules interact with non-polar molecules?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
