What is the importance of carbon compounds?
The Chemical Basis for Life. Carbon is the most important element to living things because it can form many different kinds of bonds and form essential compounds.
What are the four main families of small organic molecules in the cell?
Most, but not all, of the carbon-containing molecules in cells are built up from members of one of four different families of small organic molecules: sugars, amino acids, nucleotides, and fatty acids. Each of these families contains a group of molecules that resemble one another in both structure and function.

Why is Pluto no longer a planet?
Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
What are the 7 old planets?
In classical antiquity, the seven classical planets or seven sacred luminaries are the seven moving astronomical objects in the sky visible to the naked eye: the Moon, Mercury, Venus, the Sun, Mars, Jupiter, and Saturn.
Is there 8 or 9 planets?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine. If you insist on including Pluto, it would come after Neptune on the list.
Which are the rocky planets?
In our solar system, Earth, Mars, Mercury and Venus are terrestrial, or rocky, planets.
Is Earth gas or Rocky?
Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet.
Is the sun a gas planet?
It is, as all stars are, a hot ball of gas made up mostly of Hydrogen. The Sun is so hot that most of the gas is actually plasma, the fourth state of matter. As we heat up liquid, the liquid turns to gas. Gas is the third state of matter.
What are the 4 inner planets called?
The planets Mercury, Venus, Earth, and Mars, are called terrestrial because they have a compact, rocky surface like Earth’s terra firma. The terrestrial planets are the four innermost planets in the solar system.
What is the identity of the planets?
Since 2004, the IAU has defined a planet by three criteria: it must orbit the sun, be large enough to be shaped into a spherical object by gravity, and clear the neighborhood of its orbit (meaning that there are no objects of comparable size and mass around it).
What is the warmest planet?
Which is the largest planet in the world?
What God is Uranus named after?
Ultimately, German astronomer Johann Elert Bode (whose observations helped to establish the new object as a planet) named Uranus after an ancient Greek god of the sky. Bode argued that as Saturn was the father of Jupiter, the new planet should be named for the father of Saturn.
Is Earth named after a god?

What is Uranus nickname?
Uranus is known as the “sideways planet” because it rotates on its side. Uranus was discovered in 1781 by William Herschel.
Does Uranus life exist?
Uranus’ environment is not conducive to life as we know it. The temperatures, pressures and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
Is Uranus a gas giant?
A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune.
What planet rains diamonds?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.
