Which statements about geocentric model and heliocentric model are true? Select the two correct answers.

A. They both are models of the solar system.
B. They both show the position of Earth relative to the Sun.
C. They both show Earth at the center of the solar system.
D. They both show the Sun at the center of the solar system.

Answers

Answer:

A and B

Explanation:

the other 2 answers are just obviously wrong

They are both models of the solar system and they both show the position of the Earth relative to the sun. So the correct option is A and B.

What are heliocentric and geocentric models?

A cosmological concept known as heliocentrism assumes that the Sun is located at or close to the center of the solar system or the universe, with the Earth and other planets revolving around it. The Greek philosophers Philolaus and Hicetas hypothesized independently that the Earth was a rotating sphere that rotated daily around a mysterious "central fire" that controlled the cosmos in the fifth century BC.

Two hundred years later, Aristarchus of Samos expanded on this concept by stating that the Sun, together with the Earth and other planets, revolved around a certain central object.

Any solar system (or universe) structure hypothesis that places Earth at the center of the cosmos is referred to as a geocentric model. Ptolemy of Alexandria's geocentric model was the most advanced (2nd century CE). It was widely believed until the 16th century when heliocentric theories like Nicolaus Copernicus took their place.

Therefore the correct options are A and B.

Not every evosystem has large areas of similar vegetation, as the habitats in you study do. I'm areas where patches of more visually varied habitats exist, individual snails regularly move into or out of different visual surroubdings

Answers

Answer:

High diversity of organisms are present.

Explanation:

Due to the existence of varied habitats in the ecosystem, there is high diversity of organisms in that ecosystem because there are different types of habitats are present in that ecosystem. Due to presence of more habitats for organisms and suitable conditions, different types of organisms lives in that one ecosystem which increases the diversity of that ecosystem. If the ecosystem has only one type of habitat, then the ecosystem will be less diversified as compared to ecosystem having varied habitats.

Suppose an entire colony of lemmings is chased by a predator and most of them jump off a cliff and perish. Fortunately, a few of them don't jump and re-establish their colony (Re-established Colony) and a few of the jumpers land in the water, survive the fall and establish a second colony on a nearby island (Island Colony). Which of the following characterizes the type of change causing a reduction in the genetic variation that occurs in these 2 colonies?

Answers

Answer:

re-established colony is bottleneck effect and island colony is a founder effect

Explanation:

since the re-established colony was created after the death of a large number of lemmings, it was a random event so it is a bottleneck effect. the surviving lemmings that jumped into water made their own, new population, which would be a founder effect

The re-established colony is the result of the bottle-neck effect, while the island colony is the result of the founder effect. In both situations, there will be a reduction in genetic diversity.

What do you mean by Genetic variations?

Genetic variations may be defined as the presence of differences in the sequence of genes between individuals organisms of a species.

In an island colony, a founder effect may arise which states that a few individuals of lemmings from a population start a new population with a different allele frequency than the original population.

In the re-established colony, a genetic bottleneck changes the genetic variation, which develops when a population undergoes a drastic reduction in population size.

Therefore, the re-established colony is the result of the bottle-neck effect, while the island colony is the result of the founder effect.

What happens when plates meet? (4 complete sentences minimum)

Answers

Answer:

If two tectonic plates collide, they form a convergent plate boundary. Usually, one amongst the converging plates will move beneath the opposite, a process called subduction. ... The new magma (molten rock) rises and will erupt violently to make volcanoes, often building arcs of islands along the convergent boundary. When two plates are moving far from one another, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the world and erupts to make new crust on the lithosphere. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the method of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges aren't as violent as they're at convergent plate boundaries.

It's always a good idea to drink plenty of fluids, especially when you have been exercising. Drinking plenty of water helps to flush away materials that might form kidney stones. Staying hydrated is the best way to prevent kidney stones.

Problems of the Excretory System

The urinary system controls the amount of water in the body and removes wastes. Any problem with the urinary system can also affect many other body systems.

Kidney Stones

4

In some cases, certain mineral wastes can form kidney stones (Figure below). Stones form in the kidneys and may be found anywhere in the urinary system. Often, stones form when the urine becomes concentrated, allowing minerals to crystallize and stick together. They can vary in size, from small stones that can flow through your urinary system, to larger stones that cannot. Some stones cause great pain, while others cause very little pain. Some stones may need to be removed by surgery or ultrasound treatments.

What are the symptoms of kidney stones? You may have a kidney stone if you have pain while urinating, see blood in your urine, and/or feel a sharp pain in your back or lower abdomen (the area between your chest and hips). The pain may last for a long or short time. You may also have nausea and vomiting with the pain. If you have a small stone that passes on its own easily, you may not experience any symptoms. If you have some of these symptoms, you should see your doctor.

Kidney failure

7

Kidney failure happens when the kidneys cannot remove wastes from the blood. If the kidneys are unable to filter wastes from the blood, the wastes build up in the body. Kidney failure can be caused by an accident that injures the kidneys, the loss of a lot of blood, or by some drugs and poisons. Kidney failure may lead to permanent loss of kidney function. But if the kidneys are not seriously damaged, they may recover.

8

Chronic kidney disease is the slow decrease in kidney function that may lead to permanent kidney failure. A person who has lost kidney function may need to get kidney dialysis. Kidney dialysis is the process of filtering the blood of wastes using a machine. A dialysis machine (Figure below) filters waste from the blood by pumping the blood through a fake kidney. The filtered blood is then returned to the patient’s body.During dialysis, a patient’s blood is sent through a filter that removes waste products. The clean blood is returned to the body.

Urinary tract infections (UTIs)

9

Urinary tract infections (UTIs) are bacterial infections of any part of the urinary tract. When bacteria get into the bladder or kidney and produce more bacteria in the urine, they cause a UTI. The most common type of UTI is a bladder infection. Women get UTIs more often than men. UTIs are often treated with antibiotics.

10

Most UTIs are not serious, but some infections can lead to serious problems. Long lasting kidney infections can cause permanent damage, including kidney scars, poor kidney function, high blood pressure, and other problems. Some sudden kidney infections can be life threatening, especially if the bacteria enter the bloodstream, a condition called septicemia.

11

What are the signs and symptoms of a UTI?

- a burning feeling when you urinate,

- frequent or intense urges to urinate, even when you have little urine to pass,

- pain in your back or side below the ribs,

- cloudy, dark, bloody, or foul-smelling urine,

- fever or chills.
