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:
CHK2, p53, p21, cell cycle progression.
Explanation:
In a normal cell with no LFS mutation, during the G1 stage of cell cycle progression, the CHK2 activates if there is damage in the DNA. CHK2 activates p53, which is a tumor suppressor protein that will hold the cell cycle in G1/S until the DNA is repaired. The p53 protein activates p21, a protein that binds to CDK2 and stops the cell cycle. The cell cycle will continue once the damage is repaired.

Answer:
The correct answer is option a. Membranes; chloroplast.
Explanation:
Photosynthesis is the process is specific to green plants and other photosynthetic organism converting light energy into storage energy by forming glucose from carbon dioxide and water and oxygen released as a byproduct.
This process involves the green pigment present in the plants called chlorophyll located in the chloroplast. The chloroplast is a double membrane organelle present in green plants. The membranes of the chloroplast are the site of photosynthesis.
Thus, the correct answer is option a. Membranes and chloroplast
