C. The separation of sister chromosomes
Question 3 is a scientific question because it can be experimented and answered by science.
Hope that helps!
I believe the answer is B.
when an animal dies and its body decays, it can leave an imprint in the sediment. If this imprint fills in with minerals from sediment and groundwater, it can harden to form a fossil. This fossil is called a cast fossil. The fossilized imprint is called a mold fossil.
The resting potential of the neuron would be reduced from
-70mV. This is because increasing K+ ions inside the cell reduced the electro
negativity of the inside of the cell in comparison to the outside. Therefore,
the reaching the potential to induce an impulse would be easier but then the
impulse would be weaker than normal.
