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:
There are 2 types of cellular respiration i)Aerobic respiration
ii)Anaerobic respiration
Explanation:
i)Aerobic respiration: is the chemical reactions in the cells that use oxygen to break down food molecules to release energy. Its complete oxidation process that releases more energy (2830 $ J). The word equation of aerobic respiration is:-
glucose + oxygen------> carbon dioxide + water + energy.
ii) Anaerobic respiration: is the chemical reactions in cells that break down food to release energy without using oxygen. Its partial (incomplete) oxidation process that release a few energy (188 $ J) The word equation of anaerobic respiration in human muscles:-
glucose-----> lactic acid
The word equation of anaerobic respiration in yeast:-
glucose yeast alcohol + carbon dioxide
------->
Answer:
Glycogen
Explanation:
glucose is store inform of glycogen just like protein is stored as amino acid and fat is stored as fatty acid.
I found this. I hope it helps.
