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.
- 4 Farmers spray pesticides on their plants to protect the plants from being eaten by insects. Some individual insects have a genetic mutation that makes them resistant to the toxins in the pesticides. Which statement best describes how only a few resistant individuals resulted in the pesticide becoming ineffective? F The resistant insects change the toxin on the plants, making it safe for others. G The resistant insects grow larger and eat less of the plants. H The resistant insects eat the contaminated surface and leave the rest for others. J The resistant insects are able to survive to reproduce and create a population that is also resistant.
- 49 Most animals avoid eating monarch butterflies due to their bad taste. Viceroy butterflies look very similar to the monarchs. Which of these best explains how the viceroy butterfly benefits from looking like the monarch butterfly? A Viceroy butterflies are able to reproduce with the monarch butterflies. B Viceroy butterflies are able to deter predators in the same way as the monarch butterflies. C Viceroy butterflies are able to follow the migratory patterns of the monarch butterflies. D Viceroy butterflies are able to find additional sources of food used by the monarch butterflies. square
- -RISPE Upon studying these palindrome DNA sequences scientists found they matched perfectly with __ DNA, particularly __ which are viruses that invade bacteria. "CRISPR-Cas" provides sequence-specific adaptive immunity in bacteria by snipping viral DNA and integrating short virus DNA sequences in the bacteria's CRISPR locus of its genome, 11 __ refers to a special protein that is required for this allowing the cell to __ and __ viral infections. specific type of __ Essentially, the CRISPR system can __ and __ DNA.This made scientists think what if we could cure genetic diseases by cutting out mutations and adding healthy DNA sequences?
- 13 Multiple Choice 3 points Using the same horse cards on the Horse evolution Sheet, which of the following statements describes how the feet changed over time? All of the the statements correctly describe how the feet changed over time. The size of the feet got bigger over time. The number of toes on the feet decreased over time. The density of the bones increased to support a larger organism over time.
- The ancient megatherium, or giant ground sloth, had claws that were more than seven inches long and large powerful teeth, and some scientists have theorized that the presence of these features indicates that megatherium was a carnivore that hunted other Pleistocene animals for food However, megatherium fossils do not show a high ratio of proteins to carbohydrates when carbon isotopes are analyzed unlike other large carnivores from the Pleistocene epoch.such as dire wolves and ancient lions, or common carnivores of today, suggesting that __ Which choice most logically completes the text? A the evidence for megatherium's carnivorous diet must be contained in other fossils. B megatherium did not hunt other Pleistocene animals as part of a B carnivorous diet. C protein levels were higher in megatherium fossils than in dire wolf fossils. D megatherium would not have gone extinct if more protein sources had been available.
