A. They are made of some of the same matter
ex: humans and horses are both mammals. We both of bones and grow up feeding from our mothers milk. We do not have the same dna, we are not autotrophs, and we need different amounts of energy to survive
Which in turn leads to movement in the crust
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.
Answer:
ATP & ADP are nucleic acids.
Explanation:
ATP and ADP are macromolecules of nucleic acids as they are made up of structures similar to DNA.
An ADP molecule is made up of two phosphate groups, a sugar backbone (ribose) and the nucleotide adenine.
An ATP molecule is made up of sugar backbone, three phosphate groups and the nucleotide adenine.
Hence, Both the structures are similar to DNA and RNA. As the structures contain nucleotides hence ATP and ADP are nucleic acids macromolecules.
