Answer: Option A. "Cytoskeleton"
Explanation:
Cytoskeleton can be defined as the network of protein filaments in the cytoplasm eukaryotic cells interlinking from cell nucleus to cell membrane.
There are three basic types of protein fibers present in cytoskeleton that includes micro filaments (Actin filaments ), microtubules and intermediate filaments.
Microfilaments are consist many linked monomers of a protein known as actin, that combines in a double helix with a diameter of about 7 nano-meter and functions as serving tracks for myosin (motor protein).
Microtubules are arranged in a form of hollow straw like structure made up of consist of tubulin proteins having diameter of about 25 nano-meter and further consist of two subunits, α-tubulin and β-tubulin.
Intermediate filaments are the cytoskeletal element which are made up of multiple strands of fibrous proteins wounded together having an average diameter of 8 to 10 nano-meter.
Answer: Med kit, Flash light, rations.
Explanation: Med kit: Just in case someone were to get hurt, you would need the med kit since you can’t go out to a hospital.
Flash light: In most cases when a hurricane happens, the power shuts off and to have the ability to see you would need to use a flash light.
Rations: You can’t go to the store and buy food and water, so you would need to store water and food just in case you run out so you don’t starve to death, or die of thirst.
The preferred injection site is the ventral surface of the forearm and the purified protein derivative (PPD) test is an intradermal test.

Currently, the only skin test reagent for tuberculosis diagnosis that is commercially accessible is called purified protein derivative (PPD) (TB). The purpose of this work was to create a Mycobacterium tuberculosis-specific skin test reagent that would not produce false positive findings from the Bacillus Calmette-Guerin (BCG) vaccine utilizing recombinant antigens. By comparing the proteins in the M. tuberculosis culture filtrate to the proteins in PPD IC-65 using tandem mass spectrometry, 54 proteins were discovered to be shared. Top candidates ESAT 6, CFP 10, and MPT64 were overexpressed in Escherichia coli expression strains and isolated as recombinant proteins. The antigens were tested on guinea pigs that had been exposed to M. tuberculosis H37Rv and BCG to determine the best immunodiagnostic PPD combinations to use.

The skeleton is traditionally divided into two major parts: the axial skeleton, which includes the skull, spine, and rib cage; and the appendicular skeleton, which includes the appendages and the girdles that attach them to the axial skeleton.
