Convection currents direct the movement of Earth's rigid tectonic plates in the planet's fluid molten mantle.
In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading.
So, I would say the answer is:
As convection currents drift across the oceans,
they bring the pieces of Earth's crust with them as the supercontinent breaks apart.
Glad I could help, hv a good day :)
Answer:
D. 4E-BP1 binding to elF4E prevents loading of the mRNA onto the ribosome.
Explanation
In eukaryotic organisms, the eIF4E translation initiation factor functions by directing the ribosomes to the 5'-terminal cap structure of the messenger RNA (mRNA) in order to start the translation. Moreover, phosphorylation is a posttranslational modification of specific amino acids on proteins that play diverse cellular functions by altering protein stability, location, and/or enzymatic activity. It has been shown that elF4E phosphorylation is increased in response to cellular stimuli that induce translation in the ribosomes (e.g., growth factors, hormones, etc). The eukaryotic translation initiation factor 4E (eIF4E)-binding protein 1 (4E-BP1) is a repressor of mRNA translation which is phosphorylated and inactivated by growth factors and hormones, thereby inhibiting 4E-BP1 binding to elF4E and consequently activating translation.

Answer:
In the first stage of sexual reproduction, "meiosis", the number of chromosomes is reduced from a diploid number (2n) to a haploid number (n). During "fertilisation", haploid gametes come together to form a diploid zygote, and the original number of chromosomes is rest
