This article aims to highlight Moroccan students' alternative conceptions, regarding animal and to elicit their ability to classify some animals. Data was collected using the Animal Classification Test (ACT) distributed at the Moroccan secondary school at the Tangier-Tetouan regional Academy of Education And Training. The results obtained showed that students have real obstacles to classify even most known animals (goose, butterfly, crocodile, etc.). These obstacles are often misconceptions and were poorly treated and reformulated by the teaching-learning process. In fact, many students used “non-taxonomic” criteria, such as habitat and locomotion to classify animals even after learning the categories of the biological taxonomy. In addition, this article finds that high school students have almost the same alternative conceptions about animal classification as the intermediate second...

Our distance learning platform based on Moodle, is an effective alternative to continuous training in face-to-face mode. Indeed, conventional training is limited in time and space. The proposed solution allows overcoming the conventional training problems, while taking into consideration the real needs of physics teachers. The training is in agreement with collaborative learning features: Teachers are invited to build their knowledge in simulation software to solve student learning problems by cooperating with other teachers.

Acetate and butyrate kinase activities were higher in cells growing in the presence of pyruvate than glucose, whereas the level of the acetoacetate decarboxylase, an enzyme involved in solvent formation, was lower. Similar activities of glyceraldehyde-3-phosphate dehydrogenase were found in cells grown in pyruvate and glucose mediums. The transfer of C. acetobutylicum from pyruvate to glucose medium suggested that pyruvate represses the "solventogenesis."Key words: Clostridium acetobutylicum, pyruvic acid, kinase, acetoacetate decarboxylase.
