Water potential is important because it determines the direction and movement of water
The correct reference for the isotope of carbon that has 6 protons and 8 neutrons is carbon -14. (Solution: C)
Carbon-14, 14<span>C, also referred toa as radiocarbon, is a radioactive isotope.Its atomic nucleus contains 6 protons and 8 neutrons.
</span>It is used to estimate the date at which an organism died. The reason is b<span>ecause </span>carbon-14<span> decays at this constant rate.</span>
Mitochondrial DNA --> Inherited from one's mother and is found outside of the cell nucleus (E.)
Genes --> The basic and fundamental part of heredity (B.)
Mitochondria --> The small structures in the cell that are responsible for creating energy and carry several pieces of DNA (D.)
Hybridization --> Binds together DNA with a complimentary DNA sequence (A.)
Polymerase chain reaction --> Creates strands of DNA from small samples of DNA at crime scenes (C.)

<span>The essential unit of DNA packaging is the nucleosome. A nucleosome consists of a small amount of DNA wrapped up with protein. The proteins that interact with DNA to form chromatin comprise a family of basic (positively charged) proteins called histones. There are five different types of histone protein: H1, H2A, H2B, H3, and H4. Of these, two molecules each of H2A, H2B, H3, and H4 combine to form a histone octamer. DNA wraps around the octamer, making 1 3/4 turns around the protein complex. The amount of DNA associated with the histone octamer is 146 bp. The octamer plus the DNA comprise what is called the nucleosome core. A small stretch of DNA (60 bp) runs between adjacent nucleosome cores, and is known as the linker. A single nucleosome consists of one core plus a linker. The total amount of DNA involved in a single nucleosome is approximately 206 bp. Chromatin therefore consists of DNA wrapped around one histone octamer after another, like a long string of beads.</span>
