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.
- student conducted an experiment to whether talking to plants would help them to grow faster. He set up the following two groups: Group 1: spoken to and hand watered Group 2: not spoken to and watered with sprinklers After three weeks, the plants in Group 1 showed much more growth than those in Group 2. Based on the results of this experiment, which is the best conclusion? I because the student ran a controlled experiment They are not valid because the student did not control all the variables that can affect plant growth. They are valid because the dependent variable caused a change in the independent variable. They are not valid because the time frame to grow a plant is too short.
- Fill in the Blank Question The type of population I growth pattern that slows as the carrying capacity is approached, and makes an S-shaped curve on a graph, is square growth.
- The classification system for organisms has changed from seven levels to eight.This happened because scientific consensus changed as scientists learned more about organisms. scientists did not test the seven-level system often enough to lead to consensus. the eight-level system of classification is an emerging idea that needs more testing the seven-level system of clas classification was not supported by scientists.
- 1. What are stem cells? Where are they found?
- Lakesha was culturing bacteria She used aseptic technique to make sure there was no contamination. When she was finished, she used water to clean the surface of her table. She then put the sample in the incubator, removed her gloves, and washed her hands with soap and water Which error did Lakesha make in her process? A student should not culture bacteria in the lab Aseptic technique is used for chemical spills She does not need to wash her hands after culturing bacteria She should be using a disinfectant on her table not just water
