A study published in 2000 sequenced part of the mitochondrial cytochrome b gene from 61 brown bears from two sites in Alaska. One population of brown bears lives on the coastal mainland of Alaska, while a separate population lives on the ABC islands in southeastern Alaska. Mainland and ABC brown bears differ by 11 fixed nucleotide substitutions in the cytochrome b gene. This suggests that the two brown bear populations represent genetically unique clades. The researchers compared the cytochrome b sequences of the two clades of Alaskan brown bears to those of 55 polar bears. The analysis showed that polar bears and ABC brown bears differ at only three nucleotides in this gene, whereas polar bears and mainland brown bears had more differences. Based on the results of the 2000 study, how should the portion of the tree extending from branch point 7 be altered

the apgar score is 6

here are the 5 factors that are observed when calculating the apgar index:

skin color

blue everywhere - 0 points

white on the ends and pink on the body - 1 point

all pink - 2 points

heartbeat

absent - 0 points

slow - 1 point

fast - 2 points

reflexes

no answer: 0 points

responds to stimulations: 1 point

cries and coughs: 2 points

muscle tone

soft: 0 point

some bending or stretching: 1 point

active movements: 2 points

breathing

absent: 0 points

weak or irregular: 1 point

good and your baby is crying: 2 points

it is estimated that children whose score is between 8 and 10 are in perfect health and need only routine care. a score between 5 and 7 is representative of a fair condition. often this means that the child has suffered during delivery and probably needs with breathing. as a first step, your doctor will carefully rub the skin of your baby or give him oxygen with a mask.
