Answer:

Gradually released into the atmosphere by photosynthetic microbes, it formed two important gases new to fledgling Earth: breathable oxygen gas, or O2, and ozone, or O3.

The central lumens of thyroid follicles are filled with colloid, which consists of the protein __________, a molecule that binds
olga_2 [115]

The central lumens of thyroid follicles are filled with colloid, which consists of the protein thyroglobulin, a molecule that binds and stores thyroid hormone.

Thyroglobulin is a protein produced primarily by the thryroid gland. The thyroid gland is mainly made up of tiny, round shaped structures called follicles that produce and store thyroglobulin. Thyroglobulin acts as a substrate for the synthesis of the hormones (thyroxine and triiodothyronine) and also the storage of the inactive forms of thyroid hormone and iodine. Thyroxine and triiodothyronine assist in the regulation of the utilization of energy by the body.

¿Qué acciones a nivel internacional se han realizado para frenar el cambio climático?
Agata [3.3K]

Answer:

se han desarrollado protocolos y acuerdos con el compromiso de reducir la emisión de gases de efecto invernadero (especialmente en naciones industrializadas)

Explanation:

En los últimas décadas, la mayoría de las naciones industrializadas del planeta han establecido el compromiso de reducir las emisiones de gases de efecto invernadero (especialmente dióxido de carbono), esto con el objetivo de luchar contra los efectos devastadores sobre el medioambiente asociados con el calentamiento global. El primer acuerdo entre naciones fue el protocolo de Kioto establecido en 1997, donde 37 de las naciones más industrializadas del planeta se comprometieron a reducir el nivel de emisión de gases de efecto invernadero antes de 2012. Posteriormente, en 2015, en el acuerdo de París, las naciones industrializadas plantearon diversos compromisos con el objetivo de luchar contra el cambio climático. Algunas de las acciones directas más importantes que se plantearon en el acuerdo de París fueron: 1- reducir el aumento observado en la temperatura media del planeta por debajo de 2°C para las próximas décadas, 2- crear un fondo común de 100 mil millones de dólares para luchar contra los efectos del calentamiento global, y 3- cada 5 años cada nación deberá presentar en Naciones Unidas cuales han sido las medidas concretas adoptadas para mitigar los efectos del calentamiento global y los resultados de tales acciones.
