Question 7 of 402.5/ 2.5 PointsAn organism has 36 chromosomes. At the end of meiosis I, each gamete containsA. 18 chromosomes, 18 chromatids B. 18 chromosomes, 36 chromatids C. 26 chromosomes, 36 chromatids D. 36 chromosomes, 72 chromtids
Feedback:CorrectQuestion 8 of 400.0/ 2.5 PointsWhen a ligand binds to a G protein-linked receptor, the G protein
Feedback:Incorrect:Learning Objective Text: Compare internal receptors with cell-surface receptorsQuestion 9 of 402.5/ 2.5 PointsWhich environment would tend to have plants with the broadest leaves?
Feedback:CorrectQuestion 10 of 400.5/ 2.5 PointsCancer is caused by unregulated cell growth. One way to attack cancer cells is to harness the power of signaling pathways. For each type of drug, match it to the component of the pathway it would bind to.
D. G proteinE. ribosome1. A drug that mimics an extracellular growth signal ________2. A drug that blocks GTPase activity ________3. A specific kinase inhibitor ________4. A drug that interferes with transcription of certain genes ________5. A drug that blocks translation completely ________Feedback:IncorrectLearning Objective Text: Analyze intercellular and intracellular communicationQuestion 11 of 400.0/ 2.5 PointsWhat vitamin acts as a coenzyme in cell respiration and is important in alcohol fermentation?A. thiamine B. riboflavin C. niacin D. pantothenic acid
Feedback:Learning Objective: Describe the type of fermentation that readily occurs in animal cells and the conditions that initiate that fermentationQuestion 12 of 400.0/ 2.5 PointsSome cell processes are influenced by multiple signaling pathways that converge on the same molecular targets.Does this provide a selective advantage to the organism?
Feedback:Learning Objective: Analyze intercellular and intracellular communication
