While looking at the figure, the union of the left and right brachiocephalic veins is Point A.
<h3>
What are brachiocephalic veins?</h3>
- The internal jugular vein and the subclavian vein join to form the brachiocephalic veins, also known as the innominate veins, which are substantial venous systems in the thorax.
- On the right side of the upper chest, the superior vena cava is formed by the union of the left and right brachiocephalic veins.
- These blood arteries are an essential part of the circulatory system in humans because they facilitate the removal of deoxygenated blood from the head and upper limbs.
- The internal jugular vein on the right and subclavian vein on the left combine to form the brachiocephalic veins. Both the vena cava and the brachiocephalic veins lack valves.

Out of the following choices;
A.)Divergent boundaries create mountains on which to install
the stations.
B.)Energy from magma at divergent boundaries is cleaner.
C.)Divergent boundaries are unaffected by magma convection
currents.
D.)Divergent boundaries allow heat to rise faster.
The answer is D. The two diverging convention currents bring up the heat from deep below the mantle. They act
like two cogs/pulleys that complement
each other to bring up very hot asthenospheric materials. Where a divergent boundary occurs, there also occurs a
rift such as the Great Rift Valley in East Africa.

Explanation:
MPF is a protein kinase. It catalyzes the transfer of a phosphate group from ATP to target proteins.
One of the pathways which are stimulated by the MPF is an enzyme that destroys cyclin. This means it stimulates the cyclin pathway. As mitosis gets initiated, the enzyme that breaks down cyclin becomes activated, and levels of cyclin start to be dropping down. The declining levels of cyclin lead to reduced levels of the MPF.
