Answer:
An atomic force microscope is a nano-scale measurement and analysis instrument that touches the surface of a sample to be tested through a micro force-sensitive component (probe). While scanning the surface of the sample, the tiny tip of the force-sensitive component interacts with the surface of the sample. The microcantilever of the force sensitive component is deformed. The laser beam emitted by the laser diode is irradiated on the end of the micro-cantilever of the force-sensitive element. When the micro-cantilever is deformed, the reflected beam of the laser beam also changes correspondingly, and the reflected laser beam is received by the four-quadrant photodetector. The obtained information is converted, amplified, and output a voltage detection signal. The computer adjusts the amount of expansion and contraction of the piezoceramic scanner in the Z-axis direction by comparing the detection signal with a preset reference signal to realize feedback control. The computer processes the detection signal through software programming to obtain the surface topography image of the sample and the corresponding object.

Explanation:
It is expected that the rocks in a stream will eventually be transformed into a sediment and deposited in the same basin or carried away.
- As the rock body inside the water begins to absorb water, it will eventually undergo chemical weathering.
- Rock chips from other bed-loads carried by the flowing stream will cause the breaking down of the rock mass in the stream mechanically.
- The above processes are classified as weathering.
The stream can erode its own bed causing the washing away of the weathered rock materials. Stream erosion occurs when weathered materials are washed away either in solution or as bed load moving on the base of the stream.
During transportation, the materials are carried away to nearby basins where the sediments are deposited under gravity.

Answer:
The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
Explanation:
A. 12 chromosomes, because sex cells (gametes) are haploid, meaning they only have one copy of each chromosome
