Final answer:
Polyglycolide would be called a polyester because its monomers are linked by ester bonds, which is analogous to how nylon is called a polyamide.
Explanation:
If nylon is referred to as a polyamide due to its monomers being linked by amide bonds, then by analogy, one would call polyglycolide a polyester. This is because its monomers are linked by ester bonds. Polyester is another category of synthetic polymer, like those used in Dacron and Mylar, and it is known for its use in clothing, tapes, and high-tech sails for sailboats.
Similar to polyamides, polyesters are formed by a condensation reaction where small molecules such as water are lost during the polymerization process.

What is the advantage of the rough surface lining of the intestine?
Final answer:
The rough surface of the intestine, characterized by villi and microvilli, greatly expands the surface area for digestion and absorption, slows the passage of chyme, and ensures efficient nutrient uptake into the blood and lymph vessels.
Explanation:
The advantage of the rough surface lining of the intestine, such as the villi and microvilli, is that it significantly increases the surface area available for nutrient absorption. The mucosa of the small intestine is wrinkled and covered with villi, which number about 20,000 per square inch, and each villi is topped with even finer projections called microvilli, further boosting the surface area. This anatomy allows for maximum exposure to digestive enzymes and efficient absorption of nutrients into the bloodstream.
These structures not only enhance the surface area but also slow down the passage of chyme, providing more time for digestion and absorption of nutrients. The internal structure of each villus includes a dense network of blood and lymph vessels, which transport the absorbed nutrients throughout the body. Hence, the bumpy interior of the intestines, which can be likened to a shag carpet with folds, is foundational to the digestive and absorptive functions of the small intestine.
Overall, this complex interior design allows for a staggering increase in surface area – up to 600 times compared to a smooth tube – which is crucial for effective nutrient uptake. More surface area equates to more interaction with enzymes and nutrient molecules, facilitating a more efficient and thorough absorption process.

Short Tandem Repeat (STR) analysis could be a common biological science method accustomed compare allele repeats at specific loci in DNA between two or more samples.
Further Explanation
A brief tandem repeat could be a microsatellite with repeat units that are 2 to 7 base pairs long, with the quantity of repeats varying among individuals, making STRs effective for human identification purposes. This method differs from fragment length polymorphism analysis (RFLP) since STR analysis doesn't cut the DNA with restriction enzymes. Instead, polymerase chain reaction (PCR) is utilized to get the lengths of the short tandem repeats supported the length of the PCR product.
STRs are short sequences of DNA, normally of length 2-5 base pairs, that are repeated numerous times during a head-tail manner, i.e. the 16 bp sequence of "gatagatagatagata" would represent 4 head-tail copies of the tetramer "gata". The polymorphisms in STRs are thanks to the various number of copies of the repeat element that may occur during a population of people.
STR analysis could be a tool in forensic analysis that evaluates specific STR regions found on nuclear DNA. The variable (polymorphic) nature of the STR regions that are analyzed for forensic testing intensifies the discrimination between one DNA profile and another. Scientific tools like FBI approved STRmix incorporate this research technique. Forensic science takes advantage of the population's variability in STR lengths, enabling scientists to tell apart one DNA sample from another. The system of DNA profiling used today relies on PCR and uses simple sequences or short tandem repeats (STR). This method uses highly polymorphic regions that have short repeated sequences of DNA (the most typical is 4 bases repeated, but there are other lengths in use, including 3 and 5 bases).

what is the function of the sinoatrial node?
The sinoatrial (SA) node is the heart's primary pacemaker, generating electrical impulses to initiate normal sinus rhythm. Located in the right atrium, it coordinates the heart's contraction by setting a rhythm of 60-100 beats per minute. If the SA node fails, the AV node can act as a secondary pacemaker.
The sinoatrial node (SA node) plays a crucial role in the heart's electrical system. Here are its primary functions:
Impulse Generation: The SA node generates electrical impulses (action potentials) that set the pace for the heart's rhythm.Primary Pacemaker: It is known as the heart's primary pacemaker because it has the highest rate of depolarization and initiates the normal sinus rhythm.Location and Structure: Located in the right atrium, the SA node consists of specialized cardiac muscle cells (myocardial conducting cells).Rate of Discharge: These cells typically discharge at a rate of 60-100 beats per minute in a resting adult.Coordination of Contraction: The electrical impulses generated by the SA node travel through the heart's conduction system, ensuring smooth and coordinated contractions.Backup Mechanism: If the SA node fails, other components like the atrioventricular (AV) node can take over its pacemaking role, although at a slower rate.Blood glucose levels are regulated by secretions of ________ by the pancreas.

The DNA sequences that make up the genetic code of an organism determine which traits the organism will exhibit. How are the instructions coded by DNA translated into an organism's physical traits?
DNA is a genetic material, which is present in the nucleus of a eukaryotic cell. The coding part of the DNA, known as genes makes up the genome of an organism.
DNA is a double-stranded helical structure, which is made up of a pentose sugar, nitrogenous bases, and phosphate backbone.
The nucleotide sequence in the DNA is translated into the proteins via transcription and translation.
These proteins or the long chain of amino acids code for the phenotypes or physical traits of an organism.
The base pairs are read in the form of triplets, known as codons. Each codon represents an amino acid, which is then linked to form a long chain.
Thus, the instructions are coded in the form of codons or triplets, which help in the translation of DNA to proteins.
