<span>Valence is defined as number of electrons that are present in the outermost orbital. Oxygen is in the 16th column of the periodic table and the total number of valance electrons is determined by units place digit of the column position which is 6 for oxygen. The outermost orbital is the high energy level and there are two in that orbit. So the valance is +2.</span>
<span>The battery which Ryan kept in fridge, assuming it was well protected from any moisture or water, it would tend to play the CD longer than the one stored in a desk drawer. This is because storing batteries in a cool dry location while protected from any moisture or water, can help to prolong shelf life. This is due to the fact that low temperatures tends to slow down the electric current flow within the electrolyte fluid inside the battery, hence, the rate of power dissipation is reduced thus slowing down of the power drain from battery by the electric current flow .
Thus, the battery stored in the fridge tends to have lost less power, if any, compared to the one stored in a desk drawer.</span>
The three major clades of bilaterian animals are the <span>ecdysozoa, lophotrochozoa, and deiterstomia.
Ecdysozoa are organisms that include insects, crustaceans, chelicerata, and myriapods. Lophoytochozoa include fossil organisms. Deiterstomia include chordata, echinodermata, and hemichordata.
Bilaterian animals have bilateral symmetry, meaning that they have a head, and a tail, as well as back and belly.

Answer:
The hemocytoblast (option B) are the parent cell for all formed elements of blood
Explanation:
All blood cells are originated from a common stem cell, which is called a pluripotent stem cell. It is capable of giving rise to any of the blood cells maintaining its existence through mitosis. By dividing pluripotent stem cells, new cells are originated, which become multipotent and differentiate into lymphoid (NK cell and the polymorphonuclear cell) or myeloid cells (megakaryocite); always respecting the original quantity.
