What is the difference between a saturated and an unsaturated fatty acid? Which would you find in olive oil?
Which would you find in butter? 7. What are the parts of one triglyceride? 8. What happens to protein structure
when proteins are denatured? nucleotide?
Explain the difference between a nonpolar covalent bond and a polar covalent bond. 15. Make an electron distribution diagram of water. Which element is most electronegative? Why is water considered a polar molecule? Label the regions that are more positive or more negative.
The alteration of an atom for the Share of a covalent bond For 14. Explain the difference between a nonpolar covalent bond and a polar covalent bond. 15. Make an electron distribution diagram of water. Which element is most electronegative? Why is water considered a polar molecule? Label the regions that are more positive or more negative. (This is a very important concept. Spend some time with this one!) 16. What bonds connect the atoms of hydrogen and oxygen in a molecule of water? 17. What bonds enable a gecko to climb a wall?

The purpose of the aseptic technique is to control the conditions of the work environment so that sterile media remain that way until inoculated deliberately by the lab worker (you). The two tubes represent the "before" and “after" results when this is accomplished — a sterile medium is inoculated and grows to produce a pure culture of the unknown organism. List three precautions taken in the wet lab to reduce accidental and unwanted inoculation (also known as “contamination") of sterile media.
Explain the differences between an ion pump and a channel protein (e.g. aquaporin). Specifically, what are their functions and what type of transport do they use? Answers longer than four sentences will automatically only receive half credit.
The primary mechanism of action of organophosphate pesticides is the inhibition of carboxyl ester hydrolases, particularly acetylcholinesterase (AChE). AChE is an enzyme that degrades the neurotransmitter acetylcholine (ACh) into choline and acetic acid.
Different types of chlorophyll are found in plants. Provide 2 to 3 sentences on what you found. What would happen to a plant if they were to be placed under a light that emitted a wavelength of 525 nm? Would that plant survive?
What happens to molecules in a chemical reaction? Making and breaking of chemical bonds 21. Draw the
photosynthesis reaction from your book (refer to Concept 2.4, page 41). Label the reactants and the products.
Briefly outline the cycle by which energy is stored in and released from ATP. Discuss how ATP is critically important to cellular chemical processes. Describe the specific mechanisms of enzyme function. Pick a specific enzyme and describe its function and the importance of that function to life. Discuss how the loss of that enzyme would disrupt living processes.
Which of these statements describes the cause of ocean acidification mentioned in the video? Group of answer choices. The increase in wealth generated by industrialists and entrepreneurs since the Industrial Revolution caused an increase in carbon dioxide production.
