1. Using the image of the cross section of the Grand Canyon on this worksheet, explain the geologic history of the area. You will start with the layer Vishnu Schist and end with the Redwall Limestone. Make your answers in bulleted points or just follow the numbers and list each change. You do not have to do the entire picture! Your job is to list the name of the layers starting at the bottom and move your way up. You also need to give the environmental changes that occur in each layer and include detail in your responses similar to what is found in the example from live class. Look at the cross section key at the bottom of the worksheet for help. 20pts.

i think the correct answer from the choices listed above is option c. the statement that is correct about   the cave and geyser would be that the cave is formed when groundwater reacts with the limestone in rocks and the geyser is formed when groundwater gets heated. hope this answers the questio

label a.   prophase

label b. metaphase

label c: anaphase

label d: telophase

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.
