F. Stone 1 is softer and experienced a greater physical reaction.
Physical reaction is when an object's appearance changes, not the identity (which would be chemical reaction). Because stone 1 is softer, it would be easier to change its physical property. Since stone 2 is harder, it's more durable and therefore harder to change.

The entire cardiac cycle is as follows:
- Deoxygenated blood enters the right ventricle from the superior and inferior vena cava.
- The right atrium pumps the deoxygenated blood to the right ventricle.
- From the right ventricle, the deoxygenated blood moves to the lungs via the pulmonary artery.
- After gaseous exchange, the oxygenated blood returns to the heart into the left atrium via the pulmonary vein.
- From the left atrium, blood moves to the left ventricle.
- Oxygenated blood is pumped by the left ventricle into the aorta which supplies blood to all parts of the body.
- Deoxygenated blood, collected from the body again enters into the right atrium via the vana cava.
Answer:
Schwann cells or neurilemma cells are the cells which form the myelin sheath around neuronal axons in the peripheral nervous system (PNS) only.
Neurilemma is the collective term used for cytoplasm and nuclei present around the myelin sheath which helps in the regeneration process of nerves.
A Schwann cell surrounds the axon, invaginate it and the plasmalemma of the Schwann cells joins and from a double membrane structure called mesaxon. This mesaxon starts wrapping the axon in spiral fashion and cytoplasm start condensing into the compact myelin sheath.
Look to see if the compound is ionic or not, then follow the rules for prefixes and suffixes of the compound.
Answer:
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1
Explanation:
ΔG°' for Citrate is +6.64 kJmol-1
ΔG°' for Isocitrate is -267 kJmol-1
ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant
ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1
