| The "Blackawton Bees" article was eye-opening primarily because: | it was conducted by a class of 8-10 year old children |
| Which of the following was demonstrated in the "Blackawton Bees" article: | none of the above were demonstrated |
| Prostaglandin and fatty acids are examples of the bimolecular class: | lipids |

| Within cells, the ____ is the site of protein synthesis and the ____ is the site of lipid synthesis: | rough endoplasmic reticulum, smooth endoplasmic reticulum |
| This individual is known for co-developing Cell Theory: | Schwann |
| In physiological systems, enzymes are proteins that decrease chemical reaction rates so that cells have the necessary time to make use of the products of the reaction: | false |
| Which of the following are functions of proteins at the cellular level: | all of the above |
| When blood glucose gets too low, glucagon from the pancreas is released into the bloodstream causing increased glucose release into the blood. Once blood glucose levels increase to a certain point, glucagon release is stopped. This is an example of: | negative feedback |

| A scientific ____ is a testable, explanatory statement whereas a scientific _____ is a principle that incorporates many facts into a single, coherent explanation: | hypothesis, theory |
| Independently derived phylogenies: | occur when data from sources (e.g., genetics, morphology) are used to construct evolutionary histories |
| Regarding mutation and natural selection: | natural selection results in evolution because of heritable genetic variation, in part generated by mutations |

| A chemical binds to a receptor and prevents a biological response; this is an example of: | a receptor antagonist |
| Pheromones are examples of this catergory of chemical messenger: | ectocrine |
| A particular chemical messenger is known to bind to g protein-coupled receptors to cause a change in cell metabolism.It is also known that this chemical messenger does not have the capacity to directly interact with any receptors inside the cell.Giveninfo | the chemical messenger most likely is made of amino acids |
