name two conclusions that have been drawn about harappan civilization

Answers

They did not have big differences between social classes and had extensive trade with nearby people
Final answer:

The Harappan civilization is known for its advanced urban planning and civil engineering, as well as the lack of political power concentration in the hands of hereditary monarchs.

Explanation:

The Harappan civilization, also known as the Indus Valley Civilization, was notable for two main aspects. First, it showed a tremendous understanding of urban planning and civil engineering. This is evident from their construction of advanced drainage systems, orderly streets, and the creation of standardized bricks. These discoveries suggest that the society was well-organized and technologically advanced for its time. Second, it is believed that the Harappan civilization did not hold political power in the hands of hereditary monarchs, as was the case with many concurrent civilizations.

Indicative of this is the common culture defined by shared architectural and societal norms, suggesting a unified central authority. Additionally, despite the large size and population of this civilization, the society showed little to no war dominance or monumental architecture used to display power or influence. Instead, the civilization seemed to progress holistically, progressing technologically, artistically, and spiritually.

A tobacco plant is heterozygous for the genes for long stems (Ss), large leaves (Ll), and fibrous roots (Rr). It is crossed with another tobacco plant with genotype ss ll rr. How many of the 80 offspring of this mating will be heterozygous for all three genes? These genes are not linked. Hint: create three separate Punnett squares and use the product rule

Answers

Firstly, start by doing Punnett squares for each of the characteristics. Attached are the three Punnet squares, made by me, as they should look in end.

For each of the Punnet squares, one characteristic each, we find that half of the offspring will be heterozygous for that characteristic.
Therefore, according to the product rule, you should now multiply the quantity of heterozygous for each characteristic and then obtain the total part of the offspring that's fully heterozygous.

[tex] \frac{1}{2} [/tex]Ss×[tex] \frac{1}{2} [/tex]Ll×[tex] \frac{1}{2} [/tex]Rr=[tex] \frac{1}{8} [/tex]SsLlRr

Total offspring×[tex] \frac{1}{8} [/tex]=10
There is 10 plants in the total offspring that are heterozygous for all the considered three genes.

what is the function of the sinoatrial node?

Answers

since the other answer got deleted, i'll just answer it for you.

a sinoatrial node is the main pacemaker that begins each heartbeat located in the junctions of superior vena cava and the right atrium. It signals from the node that spread through the atria and determines the heart rates.

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.

From my research, the question is 'Which of the following events represented a DISRUPTION in access to the energy source needed by an organism'?
The correct option is this: A CACTUS IS MOVED FROM A SUNNY WINDOWSILL TO A DARK ROOM.
A cactus is a photosynthetic plant, that is, it has the ability to manufacture its own food via the energy obtained from the sun. The sunlight energy is very important to the cactus plant because, without it the plant can not manufacture any food and without food the plant will die. When the cactus plant is moved to a dark room where there is no sunlight that it can use to manufacture food, this will cause a disruption to the plant's access to energy source of sunlight.

Select all the reasons why strs are commonly examined in dna profiling.

Answers

STRs is an abbreviation for "Short Tandem Repeats," which are repeated DNA segments, around 2-6 base pairs long. 
 
It is also used in DNA typing/profiling to compare specific loci on DNA from two or more samples. It is commonly used in forensic analysis to distinguish one DNA profile to another because there is very little chance that the STR pattern at all the loci of the DNA of one person is identical to another (unrelated person). In addition, the high variability in the number of repeats of the STRs makes it extremely variable to discriminate DNAs of different individuals. 

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).

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?

Answers

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? Instructions coded by DNA sequences are translated into proteins which express 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.

What is the advantage of the rough surface lining of the intestine?

Answers

The rough lining of the intestine is an integral part of the digestive tract. The rough lining greatly increases the intestine's surface area. This is important because it allows the intestine to absorb more nutrients.

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.
