The atomic number is 5. The atomic number gives the number of protons. Protons which have a positive charge are balanced by an equal number of electrons in a neutral atom. Boron number 5 has five protons and therefore as a neutral atom also has five electrons. Boron atomic number 5 has five electrons in its ground state. Commonly Boron will lose 3 electrons leaving 2 electrons in its most common ionic form.

Question states there is an issue with the sound of blood flowing through the aorta, therefore the answer is D
There is no carbon dioxide balance in biomass output or input. There is no dynamic equilibrium since carbon dioxide is being released at various rates. Geologically carbon dioxide concentration was very high for a long time and high enough to preclude evolving oxygen breathes until when carbon dioxide was locked up in plant life and oxygen levels raised by cyanobacteria and algae.
Oceans release carbon dioxide or it absorbs less carbon dioxide which causes a rise in temperature which feeds back. More heat is lost through evaporation which is lost to upper atmosphere then land biomass starts to pick up.
