Which of these is an opinion? A. Scientists have measured the flow from the largest rivers around the world.
B. The Arctic Ocean showed a sizeable rise in the fresh water flow it received.
C. Rivers supply important nutrients to oceans and have an effect on salt levels.
D. It is most important to study streamflow in places where many people live.

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 .. .

the match duh

explanation:

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
