The goal of environmental science is to demonstrate the importance of the interrelationships between the different physical and biological components of the biosphere and to develop a set of scientific concepts and concepts to directly assess the causes and possible relationships to crises. environmental shaking our societies.
Earth's environment is constantly changing, especially in recent years with the advent of industry, deforestation and increased pollution that has disrupted many systems at the level of the biosphere (physical and biological), so the need of environmental scientists so that it can predict future events and how to restore the biosphere system.
B) continue harassing minority players.
C) pressure Congress to integrate organized sports.
D) pressure for more Negro league baseball teams.
Answer:A
Explanation:A
Multicellular organisms need a transport system to efficiently move substances across greater distances, which is not possible by diffusion alone in larger organisms. These systems also help in maintaining balance within the body conditions.
Multicellular organisms need a transport system to efficiently move nutrients, gases, waste products, and signaling molecules between their interior and exterior environment. In simple organisms, diffusion across cell membranes is sufficient for this purpose. However, in larger multicellular organisms, diffusion is not efficient enough due to the greater distances. Therefore, they have evolved specialized systems for internal transport, like the circulatory system in humans or the xylem and phloem in plants. Additionally, a transport system helps maintain homeostasis by balancing different internal conditions such as pH, temperature, and concentration of various substances.
