Quantum Physics help us understand the properties of solids, atoms, nuclei, sub-nuclear particles and light.
The word quantum refers to discreteness.
Correct answer - A (Elephants have few offspring, so they need to protect them from predators.)
Why? - The herd is led by the oldest and often largest female in the herd, called a matriarch. They live in herds so that the young elephants stay safe from predators.
Answer: Ground water recharge includes recharge as a natural part of the hydrologic cycle and human-induced recharge, either directly through spreading basins or injection wells, or as a consequence of human activities such as irrigation and waste disposal. Artificial recharge with excess surface water or reclaimed wastewater is increasing in many areas, thus becoming a more important component of the hydrologic cycle.

The highlighted vessels branch into arcuate arteries.
Arcuate arteries- The interlobar arteries bend over to produce imperfect arches at the point where the cortex and medulla meet. The arcuate artery is the name given to this portion of the blood supply as a result. The arcuate artery divides into several tiny radial arteries, which diverge at right angles and provide blood to the cortex.
Vessels- In the blood, vessels (canals) move waste away from organs and tissues and carry nutrients to those tissues. The vasculature's participation in oxygenating the organism serves as one of its main functions and important roles.

I'm pretty sure it's chemical because the calcium carbonate from the vinegar gets into the eggshell making a reaction change the entire display of the shell making it disappear.
