Mitochondrial DNA can be taken from bone, hair, or teeth and used in DNA typing. What are the benefits to using mitochondrial DNA over nuclear DNA? Check all that apply. mtDNA requires a much smaller sample than nuclear DNA.

mtDNA is useful if the nuclear DNA is degraded.

mtDNA is inherited from the mother and father’s egg cells, unlike nuclear DNA.

mtDNA is present in all maternal relatives of the person being investigated.

i think the answer would d

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
