Question
Which vessels in our circulatory system allow molecules to diffuse across their to tissues? A. arteries B. Veins C. capillaries D. arterioles E. Both A and B The correct order of classification from most general to most specific is which of the following: A. Domain-Kingdom-Phylum-class-order-Family-Genus-Species B. Kingdom-Domain-Class-Phylum-order-Family-Genus-Species C. Kingdom-Domain-Class-Phylum-order-Genus-Species-Family D. Kingdom-Class Phylum-Domain-Genus-Order-Family-Species E. Kingdom-Class-Phylum-Domain-Genus-Order-Family-Species A dehydration reaction can also be called: A. synthesis B. hydrolysis. C. endergonic D. energy-releasing E. both A and C The plant cell's central vacuole: A. provides the plant cell with support B. stores nutrients and cellular waste products C. can be a reservoir for water D. all of the above What establishes the electrochemical gradient across a membrane to provide energy production? A. The chloroplast's stroma provides the ions B. Hydrogen ions naturally collect on the outside of the organelle membrane C. Hydrogen ions are pumped across the membrane by carrier proteins D. All of the choices establish the electrochemical gradient Diabetes mellitus is associated with: A, too much insulin in the blood B. too much glucose in the blood C. blood that is too dilute D, all of these are correct which statement is NOT true about olfactory receptors? A. they are chemoreceptors nasal cavity in humans B. they are located in the roof of the bulb C. they send information to the brain by way of the olfactory changes D. they are capable of responding to pressure as well as chemical changesExplanation / Answer
(61) D. Capilaries.
Capilaries are microvessels which connect arterioles and venules, and help to enable the exchange of water, oxygen, carbon dioxide, nutrients and waste substances between the blood and the tissues.
(62) A. Domain-Kingdom-Phylum-Class-Order-Family-Genus-Species.
Biological classification uses taxonomic ranks, including among others (in order from most inclusive to least inclusive): Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
(63) B. Hydrolysis.
Hydrolysis is a chemical process in which a molecule of water is consumed in the reactions. This is similar to hydorlysis
(64) D. All of the above.
The plant cell's central vacuole provides the plant cell with support, stores nutrients and cellular waste products, and is a reservoir for water. All of the choices are correct.
(65) C. Hydrogen ions are pumped across the membrane by carrier proteins.
Carrier proteins are driven by hydrogen ion gradients. These proteins play an important role in the transport of small metabolites across the membranes.
(66) B. too much glucose in the blood
Diabetes mellitus is a diseases in which there are high blood sugar levels over a prolonged period. DM results from the pancreas's failure to produce enough insulin.
(67) D. they are capable of responding to pressure as well as chemical changes
Activated olfactory receptors transmit information about odor to the brain. In humans, these chemoreceptors are located in the olfactory epithelium - a patch of tissue a located high in the nasal cavity.
