Convection currents are responsible for powering the movement of tectonic plates.

I hope this helps you and have a great day!!:)

The correct option is C.
Scientists believed that the earth tectonic plates are in constant motion, this motion is slow and its rates vary. The motions of the tectonic plates are caused by the convection current which is found in semi molten mantle. The convection current are created by heat within the earth surface. When a semi molten rock is heated, it become less in density compared to its surrounding and thus rises up. When the less dense molten rock reaches the crust above, it spread out and carries the tectonic plate above with it. When the molten magma cools down, it sinks and the whole process is repeated leading to continuous movement of the tectonic plates.

Answer 1:

The Correct options are <u>"A and C"</u>

Answer 2:

The Correct Option is <u>"Placing channel proteins in the membrane"</u>

Explanation:

There is a bigger number of a hydrophilic particles outwardly of a cell than within. Distinguish the conditions that could level the intracellular and extracellular convergences of this particle.  

Not embeddings any channels proteins balance the extracellular and Intracellular fixations. Furthermore, putting just intracellular coordinated increments intracellular fixation. These two alternatives aren't right.

Methylation of EZH2 by PRMT1 regulates its stability and promotes breast cancer metastasis. Cell Death Differ. 2020,
vovangra [49]

Yes, it is true that Methylation of EZH2 by PRMT1 regulates its stability and promotes breast cancer metastasis.

Enhancer of zeste homolog 2 (EZH2), a key histone methyltransferase and EMT inducer, is overexpressed in diverse carcinomas, including breast cancer.

However, the molecular mechanisms of EZH2 dysregulation in cancers are still largely unknown. Here, we discover that EZH2 is asymmetrically dimethylated at R342 (meR342-EZH2) by PRMT1.

meR342-EZH2 was found to inhibit the CDK1-mediated phosphorylation of EZH2 at T345 and T487, thereby attenuating EZH2 ubiquitylation mediated by the E3 ligase TRAF6.

We also demonstrate that meR342-EZH2 resulted in a decrease in EZH2 target gene expression, but an increase in breast cancer cell EMT, invasion and metastasis.

Moreover, we confirm the positive correlations among PRMT1, meR342-EZH2 and EZH2 expression in the breast cancer tissues. Finally, we report that high expression levels of meR342-EZH2 predict a poor clinical outcome in breast cancer patients.

Our findings may provide a novel diagnostic target and promising therapeutic target for breast cancer metastasis.
