Answer:
mRNA
Explanation:
poly-deoxythymidine (poly-dT) beads binds to polyadenylated (poly (A) molecules with high affinity because Thymidine base pairs with the Adenine of the poly(A) chain.
Since messenger RNA (mRNA) is polyadenylated after transcription in contrast to other RNA species, this method is more suitable for mRNA purification.
Alfred Wegener suggested the Continental Drift Theory.
However, this idea was dismissed by scientists. Continental Drift Theory states
that all continents were once joined together then they drifted away from each
other. It was backed by maps which showed that if continents were pulled close
together would fit each other perfectly, just like in a puzzle. However
scientists from different fields resisted the idea and accused Wegener of not being an expert of science. The strongest reason of the
rejection, however, was that Wegener could not explain how continental drift
happened.

Non Voluntary action...........
Answer:in a resting neuron, there are concentration gradients across the membrane for ... (Yes, that's kind of gross, but let's just imagine it for a second.) ... Instead, they have to use specialized channel proteins that provide a ... Because the system is in equilibrium, the membrane potential will tend to stay at the equilibrium potential.
Explanation:
It measures the relative amount of hydrogen and hydroxyl ions in water. It’s important, because it’s an indicator that is changing chemicals of water.
