Q: Answer the following question given this paragraph: http://www. chem. ufl. edu/~itl/2045/lectures/lec_d. html. Q: What happens to the temperature of matter as light is absorbed? A:

OPTIONS:
- it stays the same
- it triples
- it drops
- it increases

A: it increases

input: OPTIONS:
- pollen
- yeast
- mildew
- fungi Now, answer this question: Answer the following question given this paragraph: Do you see the organisms growing on the bread in the Figure below ? They belong to the Kingdom Fungi . Molds growing on foods are some of the most common fungi in our everyday lives. These organisms may seem useless, gross, and costly. But fungi play very important roles in almost every terrestrial ecosystem on Earth. Q: Molds growing on foods are a common type of what organisms that play very important roles in almost every terrestrial ecosystem on earth? A:
A:
output: fungi

Answer the following question given this paragraph: Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Prokaryotic cells have a single circular chromosome, no nucleus, and few other organelles. Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles. All of these cell parts must be duplicated and then separated when the cell divides. A chromosome is a molecule of DNA, and will be the focus of a subsequent concept. Q: What important organelle (that would otherwise be centrally located and crucial to the cell's survival) do prokaryotic cells lack? A:

OPTIONS:
- electrons
- molecules
- protons
- nucleus

Answer: nucleus

Problem: OPTIONS:
- water uptake
- food gathering
- protection
- gas exchange
Q: Answer the following question given this paragraph: Q: Terrestrial arthropods generally have internal surfaces specialized for what? A:
Answer: gas exchange

Problem:OPTIONS:
- natural
- gravitational
- particular
- intermolecular

Answer the following question given this paragraph: Chemical energy, the energy stored in molecules and atoms, is one type of potential energy. Certain reactions can cause this energy to be released as heat. Other reactions require an input of energy, in which case the products will store more potential energy than the reactants. When we studied phase changes, we saw a relationship between energy and the state of matter. To melt a solid or boil a liquid, energy needs to be added in order to break up the intermolecular forces holding particles together in more ordered states. The reverse processes, condensation and freezing, release energy, because more favorable intermolecular interactions are formed. Q: Which forces hold particles together in more ordered states? A:
****
A: intermolecular

Problem:OPTIONS:
- hydroceptive
- covalent
- hydroaversive
- hydrophilic

Answer the following question given this paragraph: Membrane boundaries and capturing energy In which we consider how the aqueous nature of biological systems drives the formation of lipidbased barrier membranes and how such membranes are used to capture and store energy from the environment and chemical reactions. We consider how coupled reactions are used to drive macromolecular synthesis and growth. Defining the cell's boundary A necessary step in the origin of life was the generation of a discrete barrier, a boundary layer, that serves to separate the living non-equilibrium reaction system from the rest of the universe. This boundary layer, the structural ancestor of the plasma membrane of modern cells, serves to maintain the integrity of the living system and mediates the movement of materials and energy into and out of the cell. Based on our current observations, the plasma membrane of all modern cells appears to be a homologous structure derived from a precursor present in the last common ancestor of life. So what is the structure of this barrier (plasma) membrane? How is it built and how does it work? When a new cell is formed its plasma membrane is derived from the plasma membrane of the progenitor cell. As the cell grows, new molecules must be added into the membrane to enable it to increase its surface area. Biological membranes are composed of two general classes of molecules, proteins (which we will discuss in much greater detail in the next section of the course) and lipids. It is worth noting explicitly here that, unlike a number of other types of molecules we will be considering, such as proteins, nucleic acids, and carbohydrates, lipids are not a structurally coherent group, that is they do not have one particular basic structure. Structurally diverse molecules, such as cholesterol and phospholipids, are both considered lipids. While there is a relatively small set of common lipid types, there are many different lipids found in biological systems and the characterization of their structure and function(s) has led to a new area of... Q: All lipids have two distinct domains, a hydrophobic and a what? A:
****
A:
hydrophilic
