The development of the cell theory involved

a.
different ideas from different scientists.

b.
the efforts of one scientist.

c.
work with computer models.

d.
complete agreement among scientists.

The answer is A

The development of the cell theory involved different ideas from different scientist.

To support my answer it was created to Matthias and Theodor,however, there were like many other scientists like Rudolf contributed to the theory.

I hope that's help:0

Please chose me for the Brainliest answer :) thx

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 .. .

substitution is the answer in this case
