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.
- Multiple Choice 2 points During which stage of meiosis does crossing-over occur? anaphase l of meiosis II telophase I of meiosis I prophase II of meiosis II prophase I of meiosis I
- Which is a key component of the energy molecule ATP? sodium phosphorus chlorine sulfur
- Billy and Johnny are brothers,but they do not look alike. Which one of the following pairs variation? crowing over and independent assortment menul reproduction and the cell cycle enchiness and cloning
- A snake does not have legs. Nevertheless, it has tiny hip-like bones in its midsection where legs could reasonably attach. The bones have no function. How do the hip bones of a snake provide evidence for the evolution of snakes? A. The hip bones are vestigial structures that show evolutionary descent from an ancestor that had legs. B. The hip bones are analogous structures with the leg bones of other animals, and show how they all evolved from a common ancestor. C. The hip bones are vestigial structures that show that snakes, worms and other legless animals evolved by adaptive radiation. D. The hip bones are homologous structures with the vertebrae and other bones of the snake, and show the sequence in which the vertebrate skeleton evolved.
