[{"id":1972,"question":"Quel est le rôle principal des mitochondries dans une cellule ?","option_a":"Produire de l'énergie (ATP)","option_b":"Stocker les protéines","option_c":"Synthétiser l'ADN","option_d":"Assurer la photosynthèse","option_e":"","option_f":"","bonne_reponse":"a","explication":"Les mitochondries sont les centrales énergétiques de la cellule. Elles produisent de l'ATP (adénosine triphosphate), la molécule qui fournit l'énergie nécessaire aux réactions cellulaires.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Produire de l'énergie (ATP)\", \"b\": \"Stocker les protéines\", \"c\"","_debug_options_count":4},{"id":1973,"question":"Quelle est la formule de la vitesse moyenne d'un mobile ?","option_a":"v = d\/t","option_b":"v = t\/d","option_c":"v = d × t","option_d":"v = a × t","option_e":"","option_f":"","bonne_reponse":"a","explication":"La vitesse moyenne (v) est calculée en divisant la distance parcourue (d) par le temps écoulé (t). La formule est donc v = d\/t.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"v = d\/t\", \"b\": \"v = t\/d\", \"c\": \"v = d × t\", \"d\": \"v = a × t\"}}","_debug_options_count":4},{"id":1974,"question":"Quel est le pH d'une solution acide ?","option_a":"pH \u003C 7","option_b":"pH = 7","option_c":"pH \u003E 7","option_d":"pH = 0","option_e":"","option_f":"","bonne_reponse":"a","explication":"Une solution est considérée comme acide lorsque son pH est inférieur à 7. Plus le pH est bas, plus la solution est acide.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"pH \u003C 7\", \"b\": \"pH = 7\", \"c\": \"pH \u003E 7\", \"d\": \"pH = 0\"}}","_debug_options_count":4},{"id":1975,"question":"Quelle est l'unité de mesure de la force dans le système international (SI) ?","option_a":"Le newton (N)","option_b":"Le joule (J)","option_c":"Le watt (W)","option_d":"Le pascal (Pa)","option_e":"","option_f":"","bonne_reponse":"a","explication":"L'unité de mesure de la force dans le système international est le newton (N), en hommage à Isaac Newton.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Le newton (N)\", \"b\": \"Le joule (J)\", \"c\": \"Le watt (W)\", \"d\": \"Le","_debug_options_count":4},{"id":1976,"question":"Quel gaz est produit lors de la photosynthèse ?","option_a":"Oxygène (O2)","option_b":"Dioxyde de carbone (CO2)","option_c":"Azote (N2)","option_d":"Hydrogène (H2)","option_e":"","option_f":"","bonne_reponse":"a","explication":"Lors de la photosynthèse, les plantes produisent de l'oxygène (O2) en utilisant le dioxyde de carbone (CO2) et la lumière solaire.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Oxygène (O2)\", \"b\": \"Dioxyde de carbone (CO2)\", \"c\": \"Azote (N2)","_debug_options_count":4}]
