how do the kidneys and the bladder work together??

Answers

Answer:

From the kidneys, urine travels down two thin tubes called ureters to the bladder. The ureters are about 8 to 10 inches long. Muscles in the ureter walls constantly tighten and relax to force urine downward away from the kidneys. If urine is allowed to stand still, or back up, a kidney infection can develop.

how is the air outside the cell different after photosynthesis than it was before?

Answers

Photosynthesis turns water, sunshine, and co2 into oxygen.

Photosynthesis is a process by which plants take carbon dioxide, water, and sunlight from the atmosphere and release oxygen into the air. This results into decreasing the temperature of atmosphere and maintain concentration of gases.

What happens during Photosynthesis?

Plants consume carbon dioxide, which is a greenhouse gas through the process of photosynthesis. This process involves reduction of carbon dioxide in the atmosphere which has an indirect cooling effect on the atmosphere. Plants cool the atmosphere as they release water vapor when they get hot, by a process which is similar to sweating.

About 70% of the oxygen in the atmosphere which we breathe comes from the photosynthesis of plants and algae in the ocean. Atmospheric oxygen from photosynthesis also maintains the ozone layer, which protects living organisms from harmful ultraviolet (UV) radiations which comes from the Sun.

A Algae is the main diet of tadpoles.
B Woodpeckers nest in dying trees.
с Worms dig tunnels 'n soll.
D
Gids nest in cattail plants

Answers

Answer : C

Explanation:

Soil is a abiotic factor, soil is a an extremely important abiotic factor that not only worms benefit from but also plants(worms and plants are biotic factors)

"Worms dig tunnels in soil", best describes how organisms and populations depend on abiotic factors in an ecosystem. Therefore, option (C) is correct.

What are abiotic factors?

Abiotic factors are non-living aspects of the environment that have an effect on living things. In this scenario, worms are considered to be biotic factors; however, the abiotic factor of soil is required for the worms' tunneling activity in the soil. The behavior of worms and the impact that they have on the ecosystem can all be influenced by the moisture level, texture, and nutrient density of the soil.

Therefore, choice (C) illustrates how organisms' ability to survive and perform their roles within an ecosystem is contingent on the presence of abiotic factors.

FINAL DUE TONIGHT!!! SUMMARIZE THIS INTO TWO PARAGRAPHS INSTEAD OF FOURThe sixteenth, seventeenth, and eighteenth centuries changed the world in dramatic ways. But probably, the biggest change the world saw or has ever seen was the finding and conquest of the Americas. Many are theories as to what led both the Spanish and Portuguese empires to seek these voyages, but the truth of the matter is that the main reasons that pushed Spain to support Cristopher Columbus in his trip in 1492 were, first, the desire to discover and open new trade routes to the Indies. And the second reason was evangelization, which the two Spanish monarchs believed would be empowered by colonization.When the Spanish first arrived in the Americas, their first encounter was not with any big Native tribes or settled civilizations. It was not until later on, in 1519, that the Spanish encountered true Native American civilization. And the first to find this was Hernn Corts, who between 1519 and 1521, led a war against the Aztec Empire, one of the biggest and most important of the entire continent. The Aztecs were settled in the Gulf of Mexico, in what is today Mexico itself. The Aztecs, led by Moctezuma II were really advanced people, with a federal-like way of government, cities, technology, and organized society. But like all well-organized and advanced societies, problems arose. The first was that through contact with the Spanish, many diseases unknown until then diminished the number of Natives and also because of weaponry, which allowed the Spanish to finally overcome the Aztec forces.The second empire was the Inca Empire, in what is today Peru, specifically in Cusco. Unlike its sister empire in Mexico, the Incas did not have wheeled vehicles and they did not use farm animals. They did not have a currency and they survived on the exchange of goods, instead of a market. What made them really advanced was their ability in masonry and the use of stone. Their architecture was really advanced and like the Aztecs, their cities were impressive. They also had a centralized system of government led by a king, who at the time of the arrival of the Conquistadors was Atahualpa, and the king was considered the owner of everything within the empire. They also had a very advanced system of roads that connected the central city of Machu Picchu with the rest of the Empire. It was Francisco Pizarro who in 1526 moved from Panama to the Andean region and found himself at Machu Picchu. After several trips, finally, between 1532 and 1533, Francisco Pizarro and the Spanish were able to take control of the vast Inca Empire.In the end, most of the Americas, save what is nowadays Brazil, which ended in the hands of Portugal, became part of the enormous Spanish Empire. The result was a group of colonies from which the Spanish derived the precious metal of gold and which made them really rich. The Natives, at first were enslaved by the Spanish until through intervention of the Church, black people were brought in to prevent the death of the Natives. The disease also decimated the Native population in the Americas. There was a lot of racial mixing between the Spanish and Natives, which gave origin to many new skin colors, typical of Spanish America.
