Answer:
hope the answer helped you
Explanation:
absolute age(true age) The age of a geologic phenomenon measured in present Earth years, rather than its age relative to other geologic phenomena (compare relative age)
3) C. Stomata, as I explained in my previous answer.
4) B. Nonvascular, low-hanging plants living in moist environs don't have to fight gravity nearly as much as tall ones do. So they needn't highly developed vessels to transport to their tips
5) B. Gravity, see above. The higher trees/plants grew, the further their apical structures were from ground water sources, so the lignin-supported, strong vascular tissue (phloem) allows the transport of water against gravity, using a capillary method (benefiting from the adhesive effect of water molecules).
I would use a Transmission Electron Microscope.
