After all this info you have given me, the correct one is Keystone species. As defined in sources like National Geographic, <span> These are types of plants or animals that play a unique and crucial role in the way an ecosystem functions. Without </span>keystone species<span>, the ecosystem would be dramatically different or cease to exist altogether. I hope this helps you a lot </span>
Increasing the cell's volume would reduce the efficiency of the diffusion of materials through the plasma membrane into the cytoplasm of the cell.
On the other hand, increase the surface area and decreasing the volume oft the cell would increase the rate of diffusion across the plasma membrane.
Answer:
They affect chemical reactions by lowering the activation energy, thus speeding up the reactions.
Nucleic acids / aka nucleotides
Hi, sounds like it would turn into B). Metamorphic Rock. Igneous rocks are only formed when melted rock hardens and solidifies. Sediimentary rock is formed when sediment is deposited out of air, ice, wind, gravity or even water. I Doubt it would remain a sedimentary rock so the best answer would be metamorphic rock. Hope this was correct. :)
