The so-called hypervariable regions (HV1 and HV2) of the human mitochondrial genome are sometimes used in forensic analysis. They are two noncoding regions of mtDNA, each approximately 300 bp, that show more variation in different people than any other DNA sequences. The DNA within HV1 and HV2 appears to accumulate mutations at ten times the rate of DNA sequences in the nuclear genome. Check all statements that correctly describe situations where it would be advantageous to use mtDNA (as opposed to nuclear DNA) to identify individuals. a. Very little DNA is recovered from the scene of a crime.
b. You want to determine which of two brothers is the father of a child.
c. You want to determine if two individuals are identical or fraternal twins.
d. You want to determine if the woman you've been told all your life is your mother is really your grandmother.
e. You want to determine if two people are first cousins.

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
