Answer:
Scientists discovered that the process begins when the green algae first absorb strontium, calcium and barium from water. The strontium and barium form crystals inside of each algae cell. The crystals remain inside the cells, but the algae filters out and excretes calcium and other minerals that may be present. The strontium is then isolated, and thus able to be treated.
Kirchhoff's law of thermal radiation.In heat transfer, Kirchhoff's law of thermal radiation refers to wavelength-specific radiative emission and absorption by a material body in thermodynamic equilibrium, including radiative exchange equilibrium. A body at temperature T radiates electromagnetic energy.
Answer:
23a: The priest and the levite
23b: (from wikipedia) "<em>In Jewish culture, </em><em>contact with a dead body </em><em>was understood to be </em><em>defiling.</em><em> Priests were particularly enjoined to </em><em>avoid uncleanness.</em><em> The priest and Levite may therefore have </em><em>assumed</em><em> that the fallen </em><em>traveler was dead </em><em>and avoided him to </em><em>keep themselves ritually clean."</em>
