The following is NOT of the major biogeochemical cycles D.Phosphorus cycle is D.Phosphorus cycle.

What is the difference between Carbon cycle and Phosphorus cycle?

The major distinction among carbon and phosphorus cycle is that carbon cycle interacts with the environment while phosphorus cycle does now no longer engage with the environment. Therefore, the carbon cycle is a sort of gaseous biking while the phosphorus biking is a sort of sedimentary rocks.

As in comparison to nitrates & different macro elements, decomposers take longer time to decompose any lifeless biota into phosphates. Decomposers are organisms mainly a soil bacterium, fungus, or invertebrate, that decompose natural material. These are the motives for phosphorus cycle being the slowest biogeochemical cycle.

Using complete sentences, explain how proximity to major rivers influenced the location of early cities.

Answers

Answer:

Locations along rivers meant faster travel upstream and downstream to rule territories. The city became the place where the ruler or rulers lived together in a stationary spot. The city's location along early rivers encouraged stronger government, which in turn encouraged stronger cities.

Rivers are one of the most crucial resources that played a major role in the development in ancient times. It led to river valley civilization that influenced the location and kingdoms.

What is river valley civilization?

The river valley civilization was one of the most important events that led to the establishment of many kingdoms and regions. The proximity to the river banks influenced many factors.

The cities located on the riverbanks have greater development in services including import, export, travel, agriculture, accessibility, etc. This allowed the people to practice agriculture on a large scale due to the availability of the irrigation system.

The river banks allowed the cities to grow as major trade centers and allowed downstream and upstream travel easier. This also led to the emergence of strong government systems.

Therefore, the proximity to major rivers led to river valley civilization.

The Second Law of Thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time. The First Law of Thermodynamics states that energy can be converted from one form to another with the interaction of heat, work and internal energy, but it cannot be created nor destroyed, under any circumstances.

Most fresh water fish are hypertonic, meaning their body cells contain more salt than the surrounding water. Since osmosis should push water into their cells, why don't they explode? They don'­t drink any water because they get so much from osmosis. They have adapted to live with high osmotic pressure. They urinate a lot, so the water does not build up. Their cells have adapted to absorb salt. All of the above

Answers

Answer:

They urinate a lot, so the water does not build up.

Explanation:

Freshwater fishes are fishes that live in freshwater habitat i.e. little or no salt. This means that the fishes are hypertonic (have more salt) to their external environment. Due to their hypertonicity, freshwater fishes tend to take in more water via osmosis.

Freshwater fishes, however, do not explode despite this phenomenon because they pass out the excess water via urine waste. Freshwater fishes urinate a lot, hence, the absorbed water does not build up in their bodies.
