List the cardiovascular and cardiac features unique to the fetus and describe their role in fetal circulation; explain the fate
STatiana [176]

Cardiovascular features unique to the Fetus:

Fetal circulation is characterized by low systemic vascular resistance (SVR) with high systemic blood flow and high pulmonary vascular resistance with low pulmonary blood flow.

<h3>What is fetal circulation?</h3>

The embryonic circulatory system directs blood that needs oxygen through three shunts, or microscopic tunnels. These shunts are intended to avoid forming organs like the liver and lungs while the fetus is still in the womb.

The foramen ovale, which carries blood from the right atrium of the heart to the left atrium, and the ductus arteriosus, which takes blood from the pulmonary artery to the aorta, are the two shunts that bypass the lungs.

Through the placenta, the mother's blood supplies the fetus with nutrition and oxygen. The enhanced blood divides into three branches as it travels via the umbilical cord to the liver.

reasons why we can conclude that the rise of the water in the glass tube is due to root pressure and not transpiration or capill
ycow [4]
The transpiration pull is just one of the mechanisms that explain the movement or translocation of water in plants, particularly water ascent in tall trees. There is no single exacting explanation as yet for the ascent of water but several theories have been proposed. Of these, the one which has gained wide support is the cohesion-tension theory which recognizes the crucial role of<span> transpiration pull</span><span> as a driving force. These theories are briefly described below.. I dont know maybe this might be helpful</span>

¿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.
