How do index fossils help scientists?

Index fossils are used by both geologists and paleontologists to study the rocks and species of the past. They help to give a relative age for the rock layers and other fossils found in the same layer.

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic
