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.
Answer:
Mitotic phase
Explanation:
The mitotic phase is a multistage process during which the duplicated chromosomes are aligned, separated, and moved to opposite poles of the cell, and then the cell is divided into two new identical daughter cells.
The first portion of the mitotic phase, mitosis, is composed of five stages which includes prophase, prometaphase, metaphase, anaphase, telophase , which accomplish nuclear division before reaching the second stage which is cytokinensis which involves the physical separation of the cytoplasmic componenets into two daughter cells.
Deforestation is one major concern with harvesting wood. There are also all types of organisms that lose their habitats.
1-refraction
2-transmission
3-reflection
4-diffraction
<u>Explanation:</u>
Refraction is the bending of a wave when it enters a medium where its speed is different.Refraction is responsible for image formation by lenses and the eye.
Transmission of light is the moving of electromagnetic waves through a material. This transmission can be reduced, or stopped, when light is reflected off the surface or absorbed by the molecules in the material.
Reflection is when light bounces off an object.Light is reflected when there is a mismatch between materials through which the light is travelling.
Diffraction is the slight bending of light. The amount of bending depends on the relative size of the wavelength of light to the size of the opening.
