The correct answer is option D.
If a girl is standing in front of a smooth surface from which a sound is reflected, the girl may hear two similar sets of sounds if she is also near the source of the sound.
For proper reflection of all sorts of energy waves, a hard flat surface is preferable. This helps to reflect waves without losing energy. Hard and smooth surfaces are best for travelling of sound waves because sound is related to pressure.

Answer:
Endospores Staining
Endospores are substances that are formed inside of specific bacterial cells which boost their survival rate in times of harsh conditions.
Gram staining alone is not sufficient to observe the endospores, which seems apparently clear when Gram-stained cells are observed.
Endospore staining employs two stains to identify endospores from other cell components.
•The Schaeffer-Fulton method employs heat to promote the primary stain (malachite green) into the endospore. Rinsing with water will well wash away the colour from the cell, as the endospore still appears to be green stained. Counterstaining pink with safranin will show the shape and location of endospores, if they are a part of the cell. The green endospores will be seen inside the pink vegetative cells or it will appear distinct from the pink cells in total. If no endospores are seen, only the pink vegetative cells will be observable.
The attached image shows a stained preparation of Bacillus subtilis revealing the endospores as green and its vegetative cells in pink coloration.
Endospore-staining procedures are essential for observing Bacillus and Clostridium, two genera of endospore-forming bacteria, production of bioterrorism agent from B. anthracis (which causes anthrax.
Answer:
C-An action potential reaches the presynaptic membrane.
E-Sodium channels on the motor end plate open.
A-Sodium enters the muscle fiber, creating an end-plate potential.
B-Neurotransmitter is released into the synaptic cleft.
D-Neurotransmitter binds to a receptor on the postsynaptic membrane.
Explanation:
In the neuromuscular junction, there is a presynaptic membrane, a postsynaptic membrane, and between these two, there is a gap called the synaptic cleft.
First, an action potential reaches the presynaptic membrane, causing the opening of sodium channels and the entering of Sodium ions to the muscle fiber creating an endplate potential. As a consequence of this, the neurotransmitters contained in vesicles travel down up to the presynaptic membrane, where they release their content into the synaptic cleft. Then, the neurotransmitters bind to the receptors in the ion channels of the postsynaptic terminal. This causes the opening of the ion channels and a rush of ion Sodium to the inside of the postsynaptic membrane, creating an action potential that will travel from cell to cell.
