When we say that a planet has a highly eccentric orbit, we mean that (a) it is spiraling towards the Sun (b) its orbit is an ellipse with the Sun at one focus (c) in some parts of its orbit it is much closer to the Sun than in other
Answer:
(c) in some parts of its orbit it is much closer to the Sun than in other.
When a planet has a highly eccentric orbit, it means that its orbit is an ellipse with the Sun at one focus. In some parts of its orbit, the planet is much closer to the Sun than in others.
Explanation:When we say that a planet has a highly eccentric orbit, it means that its orbit is an ellipse with the Sun at one focus. In other words, the planet's orbit is stretched out into an elongated shape.
The eccentricity of an orbit describes how elongated or circular it is. If a planet has a highly eccentric orbit, it means that there is a significant difference in its distance from the Sun at different points in its orbit. In some parts of its orbit, the planet will be closer to the Sun, while in other parts it will be farther away.
For example, Pluto has a highly eccentric orbit. At some points in its orbit, it is much closer to the Sun than at others.

In any particular place on Earth, certain constellations are visible in the evening only at certain times of the year because _________.
A) during some times of year, some constellations drop below the southern horizon
B) some constellations are circumpolar
C) on any particular night, we can only see stars that are directly opposite (180 degrees away from) the Sun in the sky
D) our evening view of space depends on where Earth is located in its orbit around the Sun
Answer:
Option (D)
Explanation:
Constellation usually refers to the group of stars that forms a particular feature in the sky and which is visible at night. This is visible when the earth is located at the exact position from which it can be viewed. It often helps in the identification and location of the stars in space.
These constellations are visible from the earth when viewed in the evening, but only at particular times in a year. It is because the earth keeps on changing its position with respect to the sun. The earth goes around the sun in an elliptical orbit, and only at a few positions, with favorable conditions such as clear sky, these constellations are visible.
Thus, the correct answer is option (D).
Final answer:
Constellations are only visible during certain seasons because our view of space at night depends on Earth's position in its orbit around the Sun.
Explanation:
In any particular place on Earth, certain constellations are visible in the evening only at certain times of the year because our evening view of space depends on where Earth is located in its orbit around the Sun. As the Earth revolves around the Sun, the night sky changes, making different constellations visible at different times. In winter, for example, we can see constellations like Orion, while in summer, these constellations are not visible at night, because they are in the daytime sky, near the Sun.
The rotation and revolution of Earth cause various astronomical phenomena such as the changing visibility of constellations, the northern and southern circumpolar zones, and the unique experiences of star visibility at different latitudes. Therefore, the answer to the student's question is (D).
Stars and constellations that are circumpolar remain visible all year round for observers at certain latitudes. At the North Pole, for example, one would see certain constellations like the Big Dipper circle the sky parallel to the horizon, while others will never rise above the horizon. Similarly, at the equator, the celestial equator passes through the zenith, and stars rise and set perpendicular to the horizon.
Astronomers discovered stars even cooler than the traditional spectral type M stars recently. Astronomers have these cool stars a new spectral type, L. If you wanted to go out and find more such type L stars, what kind of instrument would it be smart to use?
Answer:
A sensitive infra-red telescope
Explanation:
Infrared light is highly advantageous for astronomers as it helps in discovering and studying the astronomical objects that are observed in the night sky.
This infrared light is commonly used in the telescopes to study the distant stars, and by analyzing them, they are classified as different types like L or M types. These telescopes, by using the infrared light, it is able to detect the presence of stars and other astronomical bodies, and this type of telescopes helps in determining the temperature of the distant objects such as the stars, planets, and other objects.
Select all the answers that apply. Geological evidence of the age of the earth includes _____. a. radiometric dating of rocks b. fossil evidence c. comparative anatomy d. molecular clocks e. gradual processes of rock formation
Answer:
a. radiometric dating of rocks
Explanation:
Radiometric dating is a method used by geologists to date rocks by measuring the decay rate of radioactive isotopes when they lose energy. They basically quantify the unstable atoms left in rocks and compare them to the number of stable atoms.
I hope you find this information useful and interesting! Goos luck!
Answer:
radiometric dating of rocks
fossil evidence
gradual processes of rock
Explanation:
Radiometric dating confirms that Earth is ancient and explains how extremely slow processes can result in major changes to Earth’s surface. Evidence from radiometric dating indicates that Earth is about 4.54 billion years old. The geology or deep time of Earth's past has been organized into various units according to events that took place.
-The ages of Earth, Moon, and meteorites, radiometric dating has been used to determine ages of fossils, including early man, the timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of Earth's magnetic field, and the age and duration of a wide variety of other geological events and processes.

Ithilium, a European country, is able to produce more electronics than Kilim, a North American country, even though both countries use the same amount of resources. Given this information, it can be deduced that Ithilium has a(n):
Answer:
the answer is "absolute advantage"
Explanation:
Absolute advantage is a principle in economics. It is when Mr. A produces a higher quantity of goods/services than Mr. B using the same quantity of resources.
In this case, Ithilium produces more electronics than Kilim even both countries use the same amount of electricity.
In the example above, one lemur species eats only bamboo shoots. Bamboo shoots contain a high level of cyanide, a toxic chemical. This lemur species has developed a tolerance for a certain amount of cyanide. What do you think will happen over time
Answer:
A) the level of cyanide in the bamboo population will increase
Explanation:
As over the period, the lemur species will develop a resistance for the disease or the toxic chemical and thus there will be an increase of the population of the lemures that had cyanide in there blood or body. As the species have developed a resistance to this chemical.Final answer:
A lemur species that consumes bamboo shoots high in cyanide has developed a tolerance through evolutionary adaptation, and this trait could become more refined over generations, improving the species' survival prospects.
Explanation:
In the instance of a lemur species that eats only bamboo shoots, which are high in cyanide, selective pressures favor individuals with a tolerance for cyanide. Over time, if this trait is beneficial to the lemurs' survival and reproduction, we would expect the species to exhibit increased genetic resistance to cyanide toxicity. This phenomenon is an example of evolution through natural selection, where the genetic makeup of a population changes as members with beneficial traits survive to pass those traits on to offspring.
Metabolic adaptations enable species like bamboo lemurs to process toxic substances that would otherwise be harmful. Through the process of evolutionary adaptation, these lemurs have developed the ability to metabolize cyanide. If these lemurs continue to thrive on a diet containing cyanide, it suggests that their detoxification mechanisms are effective and will likely become more refined over generations. Such adaptations diminish the impact of potential predators, as the presence of toxic substances within the lemurs' bodies can deter predation.
It's important to note that evolutionary changes take time and occur over many generations. Should the environment remain relatively stable, it is probable that the lemurs' tolerance to cyanide will solidify as a key feature of the species, potentially leading to other, secondary adaptations as they continue to exploit a dietary niche that is inaccessible to other animals without this unique tolerance.
