Blood first enters the heart's right atrium. A muscle contraction forces the blood through the tricuspid valve into the right ventricle. When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery. Then it travels to the lungs
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.
The anatomy (Comparative Anatomy) chart contains the ones that say " compares the limbs of different organisms" and "compares fossilized structures to living organisms".
The cells (Molecular Biology) chart contains the ones that say "compares the genomes of different organisms" and "compares cells of organisms".
If this is for Plato there should be a chart that has one column for anatomy(Comparative Anatomy) and one for cells(Molecular Biology). Hope this helps.
