The Freshwater Biome
The freshwater biome is a complex biome that can be found all over the world. There are two major types of freshwater biomes. The first type is lotic or running which include rivers and streams. Lentic or standing is the second type; those include lakes and ponds. Then larger fish like bass, trout, and pike eat these smaller fish. Finally birds, large mammals, and humans catch the large fish. In the freshwater biome, there are several examples of symbiosis. The relationship between the freshwater sponge and spongillafly is an example of paratism. The spongillafly lays its eggs on the sponge, and then they hatch and feed off the sponge.

Finally there are also examples of mutaulistic relationships. For example some small fish enter clean the mouths of larger fish, and in exchange, they may eat whatever they clean out. There are several limiting factors in the freshwater biome. Why? • People wanted to improve the freshwater fauna by introducing freshwater predatory fish in hopes of increasing fishing in freshwater Marine ecosystems • The Delta had a higher diversity which means it already had a high commercial value 6. The mosquitofish was introduced in the Ebro Delta to fight a fatal illness. But we’re polluting our cheapest and most easily accessible supply of water. (Sampat, 2000) Distribution of Freshwater: One major issue that is likely to have a major impact on freshwater’s supply and demand in the years to come is that of distribution. Like many other natural resources, freshwater’s distribution around the globe is extremely uneven. One of the most important is the availability of sunlight. In areas with little sunlight, photosynthesis can not occur; therefore, most plants can not live. Since plants are the base of the food chain the whole ecosystem falls apart. Salinity is also a limiting factor. In freshwater areas, there must be a salinity of .05% or less for most organisms to survive. The highest densities will probably be found in the more temperate areas that organisms can adapt to more easily. The carrying capacity of the freshwater biome depends on the size, location, and availability off light. Biotic potentials in the biome are most likely extremely large. This is because the main organisms are fish, which lay eggs in numerous amounts. Dams and desalination are the two most commonly used processes world over. It should however be noted that not all countries suffering from shortage of water supply have enough resources to properly develop or employ such methods for the preservation of freshwater supply. Freshwater Resources: The Microeconomic Perspective: From a microeconomic perspective, the cost of freshwater is likely to increase sharply as soon as the planet starts running out of resources.

Jenna is helping her family decide which water filtration technology they should install in their house. which of these provides the correct reasoning for method jenna and her family should choose?(1 point)
Answer:
Explanation:
Answer: reverse osmosis because it requires low maintenance, and removes all contaminants such as bacteria and chemicals.
The water filtration technology they should install in their house is reverse osmosis because it requires low maintenance, and removes all contaminants such as bacteria and chemicals.
Reverse Osmosis Systems have a totally excessive effectiveness in doing away with bacteria (for example, Campylobacter, Salmonella, Shigella, E. coli); Reverse Osmosis Systems have a totally excessive effectiveness in doing away with viruses (for example, Enteric, Hepatitis A, Norovirus, Rotavirus).
How does reverse osmosis work ?
Reverse osmosis works through shifting water via a semipermeable membrane to filter and flush away any contaminants. Reverse osmosis structures are quality appropriate for home use and offer a surprisingly green manner to purify your ingesting water at home.

Explanation:
To solve this question, one needs to isolate the variable. To do this, subtract nine from both sides. We then get 5x < -5. If we simplify by dividing by 5 on both sides, we get x < -1. One can graph this by drawing an arrow to the left of -1. Note that one must used an open circle to demonstrate a “<” and not a “≤” sign.

what would make both a russian and american of 1960 very nervous
The 1960s was marked by the cold war between the two super powers of the World, Russia and the United States. These countries were often represented as Blue and Red on a map, blue signifying the United States and it's ally countries and Red signifying communist Soviet Union and it's allies around the world. If someone from the Soviet Union would look at the map, they would be nervous to see American Allies all around the world, including Western and Northern Western European countries, some of which were at a close distance to Moscow. On the other hand, if an American looked at the world map, they would see a Giant red Soviet Union covering all of Northern Asia and Eastern Europe. They would also see other communist countries including Cuba, where the Soviets even placed Nuclear weapons, targeted at the United States.
