freshwater ecosystems are fresher
Oceans and seas are comprised of saltwater, and rivers are comprised of freshwater(drinkable, or potable)
The Great Lakes are unique among freshwater bodies due to their size, depth, and interconnectedness. They differ from saltwater environments in their ecological significance by supporting a diverse range of species adapted to freshwater conditions, and playing a crucial role in regulating regional climate and providing habitats for wildlife.
A saltwater river has a higher salinity level due to the presence of salt in the water, which affects the types of organisms that can live in it. Saltwater rivers are influenced by tides and have a different ecosystem compared to freshwater rivers, which have lower salinity levels and support different plant and animal species.
Pigeons, like most birds, have two kidneys. These kidneys are responsible for filtering waste from the bloodstream and regulating water and electrolyte balance, which is crucial for their metabolism and overall health. The structure and function of avian kidneys differ somewhat from those of mammals, reflecting their unique adaptations for flight and other physiological needs.
Marine biomes are found in saltwater environments like oceans and seas, while freshwater biomes occur in bodies of water with low salt concentration like rivers, lakes, and ponds. Marine biomes have a higher salt content, different climate patterns, and unique biodiversity compared to freshwater biomes.
If a polder were created in a freshwater area, the process would primarily involve managing water levels to prevent flooding and facilitate agricultural use, similar to saltwater polders. However, the challenges of saline intrusion would be absent, allowing for easier management of water quality and soil health. Additionally, freshwater polders might focus more on irrigation needs rather than salinity control, potentially leading to different construction techniques and infrastructure requirements. Overall, the ecological considerations would differ significantly, emphasizing freshwater ecosystems rather than coastal environments.
Saltwater marshes are found in very specific locations in mid to high latitudes with areas of protected ocean coast lines. Freshwater marshes are found in a wide variety of locations where freshwater accumulates.
Kidneys in cats are usually lower than in humans because humans are taller and walk upright.
The renal artery supplies blood to the renal system, or the kidneys. The renal artery differ with the renal vein in containing the less concentration of co2 and more concentration of urea
Saltwater clams, such as quahogs and razor clams, are adapted to live in marine environments with high salinity levels. They have specialized mechanisms to regulate the salt concentration in their bodies. Freshwater clams, like the freshwater pearl mussel, live in rivers and lakes with lower salinity levels. They have different physiological adaptations to maintain water balance in a less salty environment. Additionally, the types of food sources and predators they encounter also differ between saltwater and freshwater clams.
