Polymers have different structures. They also have different functions. Describe how the structures of different polymers are related to their functions. Polymers come in many different types within biology. Proteins are a polymer, and are used in many areas of organisms.
Unlike marijuana, hemp has the potential to be very useful to the U.S. industry. Hemp based products could currently be used to replace many of the commonly used products today. Hemp’s ability to produce a wide range of products gives it the potential to be a big benefit to
Copper vs. Fiber The advantage of having fiber is obviously going to overcome the advantage of having copper. However, there are certain areas where copper will be better fit than fiber cables. Hard to believe but let’s just point out some advantages and disadvantages of each to see which will best fit where you want to put it. Fiber cabling is growing very fast due to how much more efficient it is than copper cabling.
Hemp can also be made into a type of plastic which biodegrades much faster than oil-made plastic, thereby reducing our dependence on oil and its
The material is behaving as a liquid because it is malleable and takes on a new shape without breaking. 10. Describe how cross linking the glue has changed its properties. The crosslinking has changed the glues molecular structure and created a polymer. The molecules have linked together to form the larger polymer molecules.
When the chromatin is dispersed and not readily stainable, it is known as euchromatin. Euchromatin is prevalent in cells that are active in the transcription of many of their genes while heterochromatin is most abundant in cells that are less active or not active. The nucleus often contains one or more nucleoli that are spherical or oval bodies composed chiefly of ribonucleoproteins. Nucleoli are usually stained with basic dyes because of their high RNA content and are generally larger in cells that are actively participating in protein synthesis. The endoplasmic reticulum (ER) is a system of interconnected membranous sacs, channels, or cisternae in the cytoplasm.
Biomass is the amount of living matter that can be used as a fuel source. Hemp is easy to transfer; so that could lead to more ecological means of transport could be utilized. Hemp is stronger than cotton and its cellulose can be used
Low density polyethylene (LDPE) – involves an older gas phase process (still used) with conditions: high pressure (1000-3000 times atmospheric), high temperature (300°C) and an initiator (an organic peroxide e.g. dibutyl peroxide, or oxygen). The resultant product has significant chain branching due to alkyl groups replacing hydrogen atoms on some carbon atoms. Consequently, the alkane chains cannot pack together in an orderly fashion, resulting in low densities and weak dispersion forces; therefore LDPE is soft, flexible and has a low melting point. The initiator isn’t strictly a catalyst as it is involved in the actual formation (one initiator molecule per ½ polymer molecule).
Isolation of Trimyristin from Nutmeg and Its Hydrolysis to Myristic Acid Compounds having complex molecular structures can be separated from natural materials. Usually they are components of very complex mixtures. To obtain pure compounds, long, tedious separation and purification procedures are often required. The triester, trimyristin, is however an exception and can be extracted from ground nutmeg seeds with tert-butyl methyl ether. Crystallization from acetone yields the pure compound.
The majority of the cells mass is composed of cytoplasm. The cytoplasm is a gel-like substance, which in typical cells is largely composed of water, with trace elements of protein, enzymes, amino acids and sugars. Supported within the cytoplasm are all of the cells internal components or organelle, the parts of a cell that define the cells nature and function. Organelle in eukaryotic cells are more numerous to the component parts of prokaryotes, though components and organelle such as ribosomes can be familiar to both. Ribosomes are responsible for assembling chains of amino acids to make protein.
