Read the paragraphs and answer the question that follows.

Over the past 500 years, four large earthquakes have occurred near the same location along a continental-continental transform fault in North America. After scientists observed a nearby stream that crossed the fault, they concluded that the earthquakes had offset the stream by 60 yards from its original course. Thus, on average, each earthquake caused the crust along the fault to slip about 12 yards. The earthquakes caused a lot of damage, as well as dramatic changes to the local ecosystem.

Another area in the fault also experienced a shift in location of 60 yards over 2,000 years. But it did so without suffering a violent earthquake. In this area, the crust along the fault slipped about an inch every year. The slip caused several rock formations and structures to develop cracks. However there was no large-scale disaster or disruption.

Which two conclusions can be drawn based on this information?

Isotonic- In an isotonic solution the solvent and the solute are equal in concentration.

Hypertonic- contains more solvent than the solute. In cases of urine, it means there is more water concentration compared to solutes such as glucose, Na ions, Cl ions or Urea.

Process of changing isotonic solution (plasma) to hypertonic solution

Blood enters the kidney through the renal artery which separates many times segmental arteries to interlobular arteries to arcuate arteries to interlobular arteries to afferent arteries which deliver blood to nephron. Afferent arterioles has a greater diameter than the efferent(carries blood from the nephron) hence forcing some components of blood out of glomerular capillaries such as water, salt, glucose, urea are passed to Bowmans capsule and are known as glomerular filtrate(contains about 20% of blood plasma) glomerular filtrate is passed from renal capsule to renal tube .Blood cells and plasma proteins are not filtered out because of their large size.

Reabsorption

Tubular reabsorption occurs through three mechanisms

 Diffusion-movement of molecules\ions particles from an area of high concentration to an area of low concentration

 active transport- a movement of molecules from  a low concentrated area to a high concentrated area against a concentration gradient by use of energy

 Osmosis-movement of water molecules from of hypotonic concentration to hypertonic concentration through a semi-permeable membrane.

Water and glucose are reabsorbed in the proximal convoluted tubule.There is a high concentration of sodium ions in the filtrate hence it moves from tubular fluids to the proximal convoluted tubule. Other substances that are reabsorbed include glucose, amino acids, lactic acids and bicarbonate ions. 80% of water is reabsorbed through diffusion.

In the loop of Henle, the remaining water, dissolved salts and urea passes through the descending loop of Henle (permeable to water and less permeable to Na, Cl, and urea) this being so it increases the osmotic gradient hence the solutes are reabsorbed by the ascending loop of Henle (permeable to Cl and Na ions impermeable to water)

In the distal convoluted tubule the anti-diuretic hormone makes cells to be more permeable to water hence allows more water to go back to the blood.

Final answer:

The kidneys excrete hypertonic urine to conserve water by reabsorbing solutes from the isotonic plasma, thus increasing the urine's osmolarity. Isotonic solutions have equal solute concentrations in the cells, whereas hypertonic solutions have higher solute concentrations, leading to water exiting the cells.

Explanation:

When the body needs to conserve water, the kidneys excrete hypertonic urine. The terms isotonic and hypertonic are relative measures of osmolarity, or solute concentration, of a solution compared to another solution. In an isotonic solution, the extracellular fluid has the same osmolarity as the cell, which means there will be no net movement of water into or out of the cell. A hypertonic solution, conversely, has a higher concentration of solutes compared to another solution, leading to water moving out of the cells into the surrounding fluid.

Plasma is considered an isotonic solution to the body's cells. To convert the isotonic plasma to hypertonic urine, the kidneys must actively reabsorb solutes from the to-be-excreted fluid back into the bloodstream, thus elevating the osmolarity of the urine. This process ensures that water is retained in the body, especially when dehydrated or when the body needs to maintain higher water retention. The kidneys' ability to adjust the osmolarity of urine is fundamental to maintaining homeostasis within the body.

The low fructose-1,6-bisphosphatase enzyme activity in the liver biopsy of the four-year-old boy leads to a decrease in glucose production during fasting. This deficiency impairs the conversion of fructose-1,6-bisphosphate to fructose-6-phosphate, causing a sudden decrease in blood glucose levels. The elevated pyruvate and alanine concentrations indicate the impairment of glycolysis.

The fructose-1,6-bisphosphatase enzyme plays a crucial role in the breakdown of glucose during fasting. It converts fructose-1,6-bisphosphate into fructose-6-phosphate, an important step in glycolysis. In this case, the liver biopsy showed that the enzyme activity was only 20% of normal, leading to a decrease in glucose production.

Normally, during fasting, glucose is released from glycogen stores in the liver to maintain blood glucose levels. However, with reduced fructose-1,6-bisphosphatase activity, the body's ability to produce glucose is impaired, causing a sudden decrease in blood glucose levels.

This deficiency also leads to the accumulation of pyruvate and alanine because the conversion of fructose-1,6-bisphosphate to fructose-6-phosphate is compromised. These elevated concentrations further indicate the impairment of glycolysis.

Answer:

Option B, result in a shortened polypeptide chain

Explanation:

Premature stop codon causes mutation which is called as non-sense mutation. In a non-sense mutation, the nonsense codon do not code for any amino acid instead they stop the coding and causes end of protein synthesis. Due to this, proteins are not synthesized to their full length and are also incomplete. These proteins are mostly nonfunctional, inactive and mutated.

Hence, option B is correct

Yes, it is possible to distinguish between plants altered by classical genetics and those altered by modern techniques by analyzing specific markers and using DNA analysis.

Yes, it is possible to distinguish between plants altered by classical genetics and those altered by modern techniques. One way to do this is by analyzing the presence of specific markers that are associated with each method. For example, classical genetic techniques often result in random insertions or deletions in the genome, which can be identified through DNA sequencing. On the other hand, modern techniques such as genetic engineering involve the precise insertion of specific genes into the plant's genome, which can also be detected through DNA analysis. Scientists can use various molecular biology techniques to analyze the DNA of plants and determine whether they have been altered using classical or modern methods.

Compact bone is the dense external layer of bones that provides protection and strength. It consists of units called osteons, which are aligned parallel to the long axis of the bone. The osteons contain a mineral matrix, living osteocytes, and canaliculi that transport blood.

Explanation:

Compact bone, also known as cortical bone, is the hard external layer of bones and surrounds the bone marrow. Its main function is to provide protection and strength to bones. Compact bone tissue is made up of units called osteons, which are cylindrical structures that contain a mineral matrix and living osteocytes connected by canaliculi. These canaliculi transport blood and the osteons are aligned parallel to the long axis of the bone. Each osteon consists of layers of compact matrix called lamellae that surround a central canal called the Haversian canal, which contains the bone's blood vessels and nerve fibers. Compact bone tissue is located in areas of bone where stresses are applied in only a few directions, helping the bone resist bending or fracturing.

Your answer is: Mammals

Calculate the number of mice infected with the virus next week and in 3 weeks based on given probabilities and the initial infected count.

The number of infected mice next week:

Initially infected mice = 200

Number of mice overcoming the virus = 0.7 * 200 = 140

Number of mice getting infected = 0.4 * (1000 - 200) = 320

Number of infected mice next week = 140 + 320 = 460

The number of infected mice in 3 weeks:

Number of mice next week = 460

Number of mice overcoming the virus = 0.7 * 460 = 322

Number of mice getting infected = 0.4 * (1000 - 460) = 216

Number of infected mice in 3 weeks = 322 + 216 = 538

The answer is Aggregation.

During plant succession new community gets established at an area which had been uninhabited. The community which gets established at the site is called climax community. The aggregation is the stage during which there is increase in population of the species which has become established in the area. The shrubs replace the small herbs. This adds up biomass by introduction of more plants with woody stem. This also proves as a source of food for future inhabitants.

A eukaryotic cell that synthesizes large amounts of protein is expected to have a significant number of ribosomes and a well-developed endoplasmic reticulum and Golgi apparatus, as well as numerous mitochondria for energy.

A eukaryotic cell that is involved in synthesizing large amounts of protein might be expected to have numerous ribosomes, a well-developed endoplasmic reticulum (ER), particularly the rough ER where ribosomes are attached for protein synthesis, and a sizeable Golgi apparatus for modifying, sorting, and packaging the proteins.

Proteins are critical to a cell's functions, and ribosomes are the macromolecular machines that synthesize proteins. The rough ER is involved in the production of proteins destined for insertion into the cell membrane, secretion, or use in lysosomes. The smooth ER is associated with lipid synthesis and detoxification processes. After synthesis, proteins are transferred to the Golgi apparatus, which further modifies them and directs them to their final destinations.

In addition to ER and Golgi, you would expect such a cell to have significant numbers of mitochondria for providing the necessary energy (ATP) required for the protein synthesis process.
