D. All of the above are correct
Answer:
Contaminación por quema de combustibles fósiles en vehículos, deforestación y uso de químicos en agricultura.
Explicación:
La contaminación por quema de combustibles fósiles en vehículos, la deforestación y el uso de químicos en la agricultura son los factores que generan problemas ambientales en nuestra comunidad. La quema de combustibles fósiles en vehículos e industrias libera gas de dióxido de carbono que aumenta la temperatura del área, la tala de árboles para uso doméstico tiene un efecto negativo en el medio ambiente. En nuestra comunidad, los productos químicos se utilizan para obtener una mayor producción que también contaminan los cuerpos de agua y los animales acuáticos afectados.
Explanation:
Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.
Answer: e.Woman; there is not enough information to tell if the nondisjunction happened in meiosis I or II.
Explanation: There is not enough information to tell if the nondisjunction happened in meiosis I or II. Nondisjunction can occur during meiosis I and meiosis II, resulting in abnormal chromosomes number of gametes. The important difference between nondisjunction in meiosis 1 and Ii is that during meiosis 1, homologous chromosomes fail to separate while in meiosis II, sister chromatids fail to separate meaning it could have happened in meiosis I or II but we were not given.
