Ayuda con la tarea de biología
La parte más complicada de aprender biología es cómo hacer que los estudiantes comprendan el mundo microscópico de la biología, cómo entrar en las células y explorar genes y moléculas. Sin embargo, con el desarrollo de la tecnología de la información, la ayuda con la tarea de biología puede desempeñar un papel importante cuando ni las palabras ni las imágenes pueden explicar completamente los puntos de biología.
QuestionAI es un software de aprendizaje de biología en línea que le ayuda a aprender y dominar el conocimiento de la biología, incluida una variedad de experimentos y ejercicios correspondientes, que es fundamentalmente diferente del ayudante común de preguntas de biología. Aquí, puede simular experimentos para reproducir los escenarios experimentales, de superficial a profundo, capa por capa, para aprender y comprender los puntos de conocimiento.

- Many scientists have believed that giraffes are solitary creatures preferring to spend their time alone instead of with others. But observations of giraffes and their behavior in recent years has suggested that these animals may be more social than we once thought.For example, scientists Zoe Muller and Stephen Harris claim that giraffes may even help each other care for one another's newborns. Which finding, if true would most directly support Muller and Harris's conclusion? Choose 1 answer: A Giraffes are able to make sounds but are rarely observed communicating with others. B Some female giraffes have been observed sniffing and licking their newborn offspring C Confrontations between a younger and an older male giraffe are frequently observed. D Female giraffes have been observed feeding young giraffes that aren't their direct offspring
- TEXTUAL EVIDENCE: EXAMPLE Jan Gimsa, Robert Sleigh and Ulrike Gimsa have hypothesized that the sail. like structure running down the back of the dinosaur Spinosaurus aegyptiacus improved the animal's success in underwater pursuits of prey species capable of making quick, evasive movements. To evaluate their hypothesis, a second team of researchers constructed two battery-powered mechanical models of S. aegyptiacus, one with a sail and one without, and subjected the models to a series of identical tests in a water-filled tank. Which finding from the model tests, if true would most strongly support Gimsa and colleagues' hypothesis? Choose 1 answer: A The model with a sail took significantly longer to travel a specified distance while submerged than the model without a sail did. B The model with a sail displaced significantly more water while submerged than the model without a sail did. C The model with a sail had significantly less battery power remaining after completing the tests than the model without a sail did. D The model with a sail took significantly less time to complete a sharp turn while submenged than the model without a.suitdid
