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.

Answer:
Television broadcasting
The transmission of visual images of moving an stationary objects, generally with accompanying sound, in the form of electromagnetic waves that when received can be reconverted into visual images.
Very high frequency (VHF)
A band of radio frequencies falling between 30 and 300 MHz; VHF signals are widely employed for television and radio transmissions. In the United States and Canada, television stations that broadcast on channels 2 through 13 use VHF frequencies, as do FM radio stations. Many amateur radio operators also transmit on frequencies within the VHF band.
Answer: 2nd picture :) (or whatever picture the last two chromosomes are)
Explanation:
The parts move, which is what translocation is.
Mitotic division in onion root cells:
- Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
- Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
- Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
- Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.
Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.
