Radiometric dating depends on radiation from carbon atoms which means only carbon based things can be dated. And life is based on carbon so basically only living things can be dated.
Answer:
diffusion
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ).
Explanation:
Autotrophic.
Dark reaction happens in the photosynthetic process of plants or autotrophs.
(a) A giant redwood tree = Autotroph
(b) A spider = Heterotroph
(c) A rose bush = Autotroph
(d) A mushroom = Heterotroph
(e) A blue whale = Heterotroph
<span>Autrophs are the organisms that have the capacity to form their own food from inorganic substances like the carbon dioxide. </span>
<span>Heterotrophs are the organisms that cannot produce their own food but depends on other animals or plants for their nutritional needs.</span>
