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.
- Relative to other primates prosimian adaptations include Larger brains. Reduced number of teeth. Tiny eye orbits. An enlarged olfactory bulb and enlarged scent glands.
- Glycogen synthetase kinase 3 beta is a protein kinase that has been implicated in many types of cancer. Depending on the cell type, the gene for glycogen synthetase kinase 3 beta (GSK3beta ) can act either as an oncogene or as a tumor suppressor. Which of the following best predicts how GSK 3beta mutations can lead to the development of cancer? A Cells with inactive GSK 3beta fail to trigger apoptosis. B Cells with inactive GSK 3beta fail to proceed past the G_(2)/M checkpoint. C Cells with overactive GSK 3beta are more likely to repair DNA damage. D Cells with overactive GSK 3beta have longer cell cycles.
- Mark for Review Glycogen synthetase kinase 3 beta is a protein kinase that has been implicated,in many types of cancer. Depending on the cell type, the gene for glycogen synthetase kinage 3 beta (GSK39) canact either as an oncogene or as a turnor suppressor. Which of the following best predicts how GSK3g mutations can lead to the development of cance? A Cells with inactive GSK3B fail to trigger apoptosis. B Cells with inactive GSK39 fail to proceed past the the Gz/M checkpoint. G_(2)/M C Cells with overactive GSK3B are more likely to repair DNA damage. D square
- Cancer cells behave differently than normal body cells.For example, they ignore signals that tell them to stop dividing. Which of the following conditions will most likely cause a normal body cell to become a cancer cell? A The environment already contains cancer cells. B The environment has an abundance of nutrients. C The environment lacks signals that would otherwise tell the cell to stop dividing. C D The environment contains mutagens that induce mutations that affect cell-cycle regulator proteins.
- Researchers studying cell cycle regulation in budding yeast have observed that a mutation in the CDC15 gene causes cell cycle arrest in telophase when the yeast cells are incubated at an elevated temperature. Which of the following statements best predicts the effect of the cell cycle arrest on proliferating yeast cells? A The yeast cells will transition out of G_(0) but will fail to complete the G_(1) phase. B The yeast cells will initiate mitosis but will fail to complete the G_(2) phase. The yeast cells will replicate their chromosomes but will fail to complete cytokinesis. D The yeast cells will replicate their organelles but will fail to complete the S phase. (D)
