Answer:
not all organisms become fossils because, not all organisms have bones
The answer is: In recent years, scientists have discovered fossils from long ago that glaciers have hidden
Its is already a balanced equation so the option a.1 would fill in for the blank.
Answer:
B because the diffusion gradient is steeper there
Explanation:
Oxygen moves in the cell through the process of diffusion which means it moves from its higher concentration towards its lower concentration. More the difference in concentration, concentration gradient will be more steeper and diffusion will take faster.
So in this case cell, B cell consumes oxygen at a faster rate because it is more metabolically active therefore as oxygen is consumed at a faster rate the concentration difference in B cell becomes high and the diffusion gradient becomes steeper so oxygen will diffuse more quickly in cell B.
