Answers

B is correct but I’m pretty sure a is also correct

Answer: the answer is a .

Explanation: kidneys do not "remove" urine from the body. They filter waste in the blood which then forms the urine. The kidney thus functions in filtration of waste products from the blood leading to urine formation.

Give an example of a hydraulic system that contains valves, briefly describe how it works, and explain how valves help it function.

Answers

Answer: A hydraulic valve properly directs the flow of a liquid medium, usually oil, through your hydraulic system. The direction of the oil flow is determined by the position of a spool. A hydraulic system can only function - as per requirements - by using valves. Thus, you should always look for the correct type of hydraulic valve to serve your intended purpose. The required size is determined by the maximum flow of the hydraulic system through the valve and the maximum system pressure.

Were there any finches that could access more than one food source? If so, which ones?

Answers

Answer:

In the mid-nineteenth century, the actual mechanism for evolution was independently conceived of and described by two naturalists: Charles Darwin and Alfred Russel Wallace. Importantly, each naturalist spent time exploring the natural world on expeditions to the tropics. From 1831 to 1836, Darwin traveled around the world on H.M.S. Beagle, including stops in South America, Australia, and the southern tip of Africa. Wallace traveled to Brazil to collect insects in the Amazon rainforest from 1848 to 1852 and to the Malay Archipelago from 1854 to 1862. Darwin’s journey, like Wallace’s later journeys to the Malay Archipelago, included stops at several island chains, the last being the Galápagos Islands west of Ecuador. On these islands, Darwin observed species of organisms on different islands that were clearly similar, yet had distinct differences. For example, the ground finches inhabiting the Galápagos Islands comprised several species with a unique beak shape

The tiny seeds the medium ground finches were accustomed to eating grew scarce. Medium ground finches with larger beaks could take advantage of alternate food sources because they could crack open larger seeds. ... They found the offsprings' beaks to be 3 to 4% larger than their grandparents'.

Hey,

So what you would do here is first choose a biome, such as the desert for example, then choose an organism that lives there, or an animal. Then think of what it is like where it lives, is it dry, cold, windy, and so force, just describing the place by its looks and climate. How would this population increase, maybe it would be if there was suddenly more food there for them, or if their ecosystem got better for them to live, then, if they populated more, how would that affect the ecosystem. Maybe some animals would die off more, or some would have to much food. Like what if the fly population suddenly doubled, for example, how would that affect the ecosystem? Now what would happen if that organism was removed? If flies were removed, spiders and a lot of other organisms would not have food, and some organisms would overpopulate because nothing would eat them. That is just an example.

Explanation:

I hope this helps, sorry if not. Have a great day!

Biome: Tropical Rainforest

Organism: Jaguar

1. Jaguars live in a range of habitats, including arid scrubland, thick tropical forests, swamps, coastal mangroves, lowland river valleys, grasslands, and mixed-conifer forests. They gravitate toward areas near rivers and streams.

2. Habitat loss, wildlife trafficking, collisions with vehicles, and retaliatory killings by landowners and ranchers who fear that jaguars will kill their livestock have significantly lowered the population numbers of jaguars and threaten them with eventual extinction.

3. If jaguars were to go extinct, the number of these animals would perhaps increase, which might change the current ecosystem, from what it is now, to a new ecosystem that will adjust to the species left.

Biome 2: Desert


Organism: Camel

1. No matter the type, camels are usually found in the desert, prairie or steppe. Though many people think that camels only live in hot climates, they do well in temperature ranges from 20 degrees F (minus 29 degrees.

2. The sudden increase in camel populations could be also related to massive import of live animals. The Arabian Peninsula countries are among the main camel importing countries.

3. A mob of feral camels moves across arid land in the Australian Outback. The animals, introduced to the area in the 1800s, are causing enormous damage to the ecosystem. ... Camels also damage salt lake ecosystems, pollute waterholes, and destabilise desert dunes, which can lead to erosion. Meaning There would be less damage to the ecosystem.

How does a prism separate white light into various colors and why are the colors always in the same order?

Answers

I believe that there is a spectrum of light in which we can see. When the white light enters the prism, it is refracted and bends into the visible light we can see of the spectrum.

The reason we always see the spectrum in the same order is because it is how our brain perceives it. Animals could see it in a different order, etc. This is just how the human brain sees it.

When light passes into the prism glass it slows down and it bends. The color red is not as bent the same way as the color violet is bent. When the colors come out of the prism, each color is bent in a different way and in a different quantity.

Answer:

2. they eat plants that get their energy from the sun
