Answer:
The nervous system is the part of an animal's body that coordinates its behavior and transmits signals between different body areas.
Tough cuticle made of proteins and chitin.
PCR is commonly used to duplicate a small section of DNA in order to make it readable by the lab
All of them are speciallized cell
#Muscle cells have evolved to carry out one highly specialized function — contraction. Muscle contractions must occur quickly and repetitively, and they must occur through long distances and with enough force to move large loads. ... A passenger car engine is only 1½ times more powerful than muscle.
#Reproductive cells include the sperm cell and egg cell. These cells have special features that allow them to come together and create a new organism that will grow and create specialized cells of its own!
#blood cells are highly specialized, well adapted for their primary function of transporting oxygen from the lungs to all of the body tissues. Red cells are approximately 7.8 μm (1 μm = 0.000039 inch) in diameter and have the form of biconcave disks, a shape that provides a large surface-to-volume ratio
#Most neurons have multiple dendrites, which extend out-ward from the cell body and are specialized to receive chemical signals from the axon termini of other neurons. Dendrites convert these signals into small electric impulses and transmit them inward, in the direction of the cell body.
SO ALL OF THEM ARE SPECIALIZED CELL BECAUSE OF THEIR SPECIFIC FUNCTIONS !
No
Infrared (IR) Spectroscopy is a set of techniques that involves the analysis of the interaction between infrared light and a molecule. Infrared spectroscopy is mainly used to determine functional groups in molecules and it can also be employed to study and identify chemicals.
IR spectroscopy cannot be used to distinguish 2-pentanone from 2-hexanone because the two structures have the same functional group. IR spectroscopy can only be used to distinguish molecules that have different functional groups.
