11. why is saline, a dilute salt solution, given through an iv to dehydrated patients,
instead of regular water?
a. the salt ions in the saline the body maintain its normal temperature.
b. regular water would alter the ph of the blood, causing it to become more acidic.
c. the salt concentration is close to that of the blood, which keeps red blood cells
from bursting.
d. the saline is more sterile than regular water, so it prevent infections due to
dehydration

Answer:

Saline, a dilute salt solution, given through an IV to dehydrated patients,  instead of regular water because " OPTION D. The saline is more sterile than regular water, so it helps prevent infections due to  dehydration"

Explanation:

The normal saline are used for the treatment of dehydration, as it contains the sodium and chlorine which can even replace the lost fluid which further helps in prevention of some electrolyte imbalance. Dehydration is the condition where the body loses the fluid as compared to that of the intake, it can be via sweating, urine etc. the saline contains potassium, sodium and glucose in it, which is needed during dehydration. Caffeinated beverages enhances more fluid excretion so it must be avoided.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .

i really wish i could answer this question for you
