Plant Roots. The root system of a plant constantly provides the stems and leaves with water and dissolved minerals. In order to accomplish this the roots must grow into new regions of the soil. The growth and metabolism of the plant root system is supported by the process of photosynthesis occurring in the leaves.
Effect: Radiogenic heat released- Cause: convection currents cycle through magma.
2.) Effect: Earth has a powerful magnetic field- Cause: Iron in earths outer core swirls due to convection currents.
3.) Effect: tectonic plates move- Cause: unstable isotopes in earth release energy.
: ) I think this is right
The enzyme responsible for that is DNA helicase.
As the left ventricle contracts, oxygenated blood leaves the heart through the aortic valve, into the aorta. The blood to lower limb flows through descending aorta, which continues down to Left Common Femoral Artery, which continues down to Left Superficial Femoral Artery, which continues down to Left Popliteal Artery. The Left Popliteal Artery gives 2 divisions.
1. Left Tibioperoneal Artery (which continues down to the Left Posterior Tibial Artery which supplies back of the foot.)
2. Left Anterior Tibial Artery (which continues down to Left Dorsalis Pedis Artery which continues down to <em>Left First Dorsal Metatarsal Artery</em> which supplies the big toe/first digit of foot.)
