Organisms that live in deciduous forests have developed unique adaptations that aid in their survival. how are the bill and feet of the platypus specially adapted for survival in their environment?

a.
close the nostrils in its bill when diving underwater; pointed bill for spearing fish for food; detect vibrations of moving prey using the pads on their feet
b.
detect the electrical discharges of prey in the sand using small pits on its bill; crush the food with grinding pads on the top and bottom of its bill; webbed feet

B.

Explanation:

detect the electrical discharges of prey in water using small pits on its bill; crush the food with grinding pads on the top and bottom of its bill; webbed feet

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 .. .

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
