What is the arthropod skeleton composed of?
Arthropods have an external skeletal structure, or "exoskeleton", usually made from a material called "chitin", a natural-made carbohydrate-based polymer. Chitin is not unlike keratin (a protein-based natural polymer, used in other creatures to make nails, claws, hair, etc) in structure.
True or false glucose stores hereditary information that can be used to make proteins?
true
How can the structure of DNA and proteins be used to document the hereditary background of an organism?
Hell naw
Permeability refers to?
Permeability is a word used to describe a property of a certain material. It describes whether it will allow another substance such as water to pass through it. To use it in example, one could say 'This cloth is all wet, so it must be permeable'
Which organic compound stores hereditary material?
Transmitting genetic info...sounds kind of like genes right? what kind of molecules are used in that? .. .. DNA and RNA of course! DNA is the "primary" genetic information holder. It is sort of like a book, in that stores all the blueprints for making life live. It stands for deoxyribonucleic acid, which is just a long word for a special-sugar-without-an-oxygen-in-the-nucleus. RNA, or ribonucleic acid, is very similar. However, your cells primarily use it as a working copy of the blueprint for life, and is used in this manner to make protein. It is also used though as hereditary material in some viruses like HIV and HTLV though.
What is the definition of corian?
Corian is a solid surface material used for countertops, sinks, and other applications in both residential and commercial settings. It is a blend of acrylic polymer and natural minerals, known for its durability, versatility, and seamless appearance. Recommended: ₕₜₜₚₛ://www.dᵢgᵢₛₜₒᵣₑ₂₄.cₒₘ/ᵣₑdᵢᵣ/₃₄₉₁₁₃/ᵥᵢₖₐₛbₐbbₐᵣ₀₀₁/
What industries have polymer jobs available?
Polymer jobs mostly refer to chemists who create new polymers in labs in order for stronger and better material to be used in everyday materials. The truth is, any job ranging from fabric creation to recycling product creation is in need of polymer chemists.
Why do you use Polymer and carbon coated Copper grids in TEM?
The copper is used to support the polymer layer on which the particles/object of interest is deposited. You need a thin layer of polymer/carbon because in TEM you measure transmitted electrons, so the electrons need to be able penetrate the material on which the sample is deposited. A few micrometers of material can already absorb all the electrons. The copper is just to support this polymer layer and to make a sample which is easy to handle.
What are the factors that influence crystallinity?
In general it can be said that the most important factor affecting the crystallinity is the structure of the components used in polymer synthesis. If the polymer synthesized has a very symmetrical structure, then we can say that a highly crystalline material will form. The tacticity of the polymer is also important factor affecting the crystallinity. If the components are reacting in an ordered way, like syndiotactic PET, the material will be highly crystalline. But if the PET is atactic then it will be highly amorphous,even if the components of the polymer are the same.
What is pHEMA?
pHEMA is an abbreviation of the polymer poly(2-hydroxyethyl methacrylate). This material forms hydrogen in water and was first used in optical implant.
What is polyvinyl plastic used for?
it is one of the polymer family which makes it a polymer
Is polyvinyl carbazole used as polymer electrlyte?
yes pvk used as electrlyte as blend with other polymer
What is a 'dry polymer'?
A dry polymer is one that is not in solution. they are used where moisture would create an issue. Sometimes dry polymer powder is added to cement so that when the cement is hydrated to make concrete, the dry polymer is hydrated at the same time. If a wet polymer, or polymer solution were used, it would react with the cement and make it unusable.
What materials are used to make lycra?
Lycra is a brand name for spandex. Spandex is a synthetic fiber made primarily from a polyurethane polymer. It is a competitor to the natural material latex.
Which polymer is used for flexboard?
synthetic
What is a polymer used for?
its used to mix dank sauce.
What goes into plastics manufacturing?
Plastics are usually synthetic organic polymers. The first step to manufacturing plastics is to get the materials. Step 2 is to synthesize the polymer. Step 3 involves compounding the polymer into a material that can be used and step 4 involves shaping the plastic into it's form.
