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.
- 1x The law of segregation tells us that the rearrangement of chromosomes into gametes is __ A determined B random
- 4 __ Over time, the climate of an island became drier, which resulted in changes to the populations of various island finch species.Finch populations with a certain beak shape thrived , while those not having that beak shape decreased. Which of the following describes a necessary condition for these changes in the finch populations to occur? A. fewer mutations B. limited food resources C. limited beak variations D. overproduction of offspring
- Which of the following is NOT one of the three keys to keeping water clean? Encouraging algae growth Reduction of pollutants Proper sewage treatment Effective cleanup of oil and gasoline spills
- __ When nurse sharks find that brightly colored red crabs move more slowly and are easier to catch than other crabs , they will change their behaviors to catch these brightly colored crabs more often] What behavioral change would you expect to see in the brightly colored red crabs over time? A. The brightly colored red crabs will leave the area to look for a habitat that does not have any predators that like to eat them B. The brightly colored red crabs will learn to avoid the predators and will not be eaten anymore after subsequent generations. C. Faster bright red crabs will survive longer will reproduce more, and will have more offspring. Over time, the bright red crabs will become faster. D. There will be no change in the behavior of the brightly colored red crabs over time. They will just learn to exist with the predators the way they are.
- 2. __ Evolution is a change in the characteristics of a population from one generation to the next One mechanism of evolution is natural selection. Which of the following riatural selections condition examples can be classified as struggle to survive? A. A family of pigs has a mutation that makes them immune to flu. B. A family of dogs has a mutation that makes them immune to rabies. C. Male rams charge at each other's heads and fight to mate with a female. D.
