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.
- 14. In which way is meiosis different from mitosis? A Meiosis produces cells without nuclei. B. Meiosis produces egg and sperm cells C. Chromosomes divide during milosis but not during meiosis. D. Mitosis results in cells with on half the number of chromosomes. Directions: Explain how Meiosis & Crossing Over each increase genetic variation. square square 17. Read the passage below and answer the question. Half of Wendy's chromosomes came from her mother and half from her father. Few of her chromosomes are identical to those of either parent because most of the genes on them have been exchanged with genes on other homologous chromosomes. What process accounts for this? A. Meiosis B. Crossing Over C. Nondisjunction D. Mitosis 18. Read the passage below and answer the question. Reproduction is very significant in the life of any organism. Scientists have observed that single-celled organisms favor asexual reproduction while multicellular organisms tend to favor sexual reproduction. What can be inferred from the observations made by the scientists? A. Multicellular organisms have fewer mutations in their genetic material. B. Multicellular organisms produce large numbers of offspring in very little time. C. Multicellular organisms produce genetically diverse offspring to survive changing environments. D. Multicellular organisms produce genetically identical offspring to survive changing environments
- A student argues that viruses are nonliving and bacteria are living. Which statement best supports the student's argument? A. Viruses replicate their own genetic material while bacteria can replicate bacterial and viral genetic information. B. Viruses replicate a host cell's genetic material, while bacteria can replicate their own genetic material. C. Viruses must take over a host cell to reproduce, while bacteria are able to reproduce on their own. D. Viruses must produce their own ATP to replicate, while bacteria must use viral ATP to replicate.
- How would genetic drift affect a population?
- a During melosis, an organelle breaks down to allow chromosomes to separate. This part then redevelops during the last phase of the cycle. Which part of the cell should be added to Figure 2 to make the diagram more accurate? A vacuole B mitochondrion C cell membrane D nucleus
- During pasteurization, food I is heated to a high temperature for a specified period of time and immediately cooled. What is a benefit of having foods pasteurized? C A. Reducing the transmission of diseases by pathogenic bacteria o B. Making milk proteins and fats more digestible during digestion C. Increasing the nutritional value of milk and other daily products D. Introducing beneficial bacteria and vitamins into food products
