1 kilometer = 6.68 × 
(<<<AU is in scientific notation here)
To convert 300 billion kilometer (3,000,000,000 km) into AU you must multiply the kilometer by the equivalent of 1 km in AU (6.68 × )
3,000,000,000 × (6.68 × ) = 20.04 AU
Hope this helped!
A halite crystal belongs to the cubic crystal system. The other five crystal systems are monoclinic, triclinic, orthorhombic, tetragonal, and <span>hexagonal.
The cubic crystal system is characterised by</span> <span>the way the atoms in the mineral are arranged in the three </span><span>dimensional</span><span> shape of a </span>cube. The halite crystal has this shape. Attached is an image of it.
This has happened before in Yellow Stone National Park in CA. Removing a species form the Pyramid causes the ecosystem to collapse, as species become over hunted and others are starved. One type of organism could become overpopulated, therefor lack of natural variation.
The correct answer is: Insulation
I hoped that helped :)
In amino acids, the carboxyl group acts as an acid.
Answer: Option B
<u>
Explanation:
</u>
The molecular formula of the carboxyl group is -COOH. It is composed of one carbon atom bonded with oxygen atom and hydroxyl group.
During ionization process, it leads to the formation of two ions namely a positive ion called 
, whereas a negative ion called 
. Due to the formation of ions, which is nothing but a proton, the carboxyl group present in the amino acid act as an acid.
