Explaining Convection Currents Which statement explains how convection currents affect the movement of plates?
Gravity pulls one edge of a plate down into the mantle, which causes the rest of the plate to move as well.
O Heat from Earth's interior causes lithospheric plates to collide at convergent plate boundaries, causing
volcanoes
O Heat from Earth's interior causes currents of hot rising magma and cooler sinking magma to flow, moving the
crust along with them.
As convection currents drift across the oceans, they bring the pieces of Earth's crust with them as the
supercontinent breaks apart.
Intro

'which of these statements about the scientific method is not true? all experiments must follow the same number of steps in the procedure. experiments may be repeated several times. some unexpected results can be beneficial. experimental results may or may not support the hypothesis.

Apaleontologist finds a plant fossil that shows that the plant had seeds. what can the paleontologist conclude?

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions,because prokaryotes don't have nuclei.
