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.
- Which of the following statements correctly compares the two types of ecological succession? In primary succession, the pioneer species reaches intermediate species much faster because species experience less competition from the disturbance. In primary succession reaching climax community is much shorter than in secondary succession because the ecological disturbance is minimal. In secondary succession, the pioneer species become established quicker because the soil maintains its nutrients. In secondary succession, the intermediate species are more diverse because the community has fewer niches.
- A strong storm destroyed a lot of mature species in a community.but left the soil intact. This caused an ecological succession event. After several years what would most likely be seen after the pioneer species if this area remained undisturbed? Grasses and plants Small bushes and trees Lichen and moss Bare rock
- (b) Scientists are interested in researching how carbon dioxide in the oceans is affecting its pH.They design a laboratory experiment in which they inject different concentrations of carbon dioxide into saltwater tanks containing calcium carbonate shells. The tanks were kept at the same,constant temperature. After several days, the scientists measured the pH of the saltwater tanks and observed its effects on the calcium carbonate shells. (i) Identify the independent variable in this experiment. (ii) Describe a control group that could be used in this experiment. (iii) Explain the effect of carbon dioxide on the pH of the oceans. (iv) Describe the effect of water temperature on the amount of dissolved gases in water. (v) Describe how the results of the experiment would change if the temperature of the tanks was decreased. (vi) Describe how a decrease in ocean pH can affect marine organisms.
- Which of the following accurately describes the function of coronary arteries? Providing oxygenated blood to tissues of the heart Draining deoxygenated blood from the heart Providing oxygenated blood to blood vessel tissues Draining deoxygenated blood from blood vessels
- An animal specis has lived inland for thousands of years. Due to a wildfore, the survivors of the population had to migrate and form a community near the coastline. Their crisinal food source was limited in this new areas however, some members found a new, nutritious food source in the waters Which of the following most likely describes the survival potential of this species? the species will unfortunately not survive because having lived inland for so long, it will not be able to catch the food source The species will unfortunately not survive because having lived inland for so long, it had not adapted to be able to enter the water. The species will most likely survive by building a new ecosystem that will draw in their food source from coastal land The species will most likely survive by adapting to the conditions of the water to be able obtain their food source from the water.
