How does increase in income affect the demand for necessities? In the case of inferior goods income and demand are inversely related, which means that an increase in income leads to a decrease in demand and a decrease in income leads to an increase in demand. For example, necessities like…
How does an excise tax affect supply? The effect of the tax is to shift the supply curve, which is S without the tax, to St. The shift is an upward shift by the amount of the tax, but the upward shift is the same as a backward shift, a…
What is the difference between plasmid and cloning vector? Main Difference Plasmid vs Vector The main difference between plasmid and vectors is that plasmid is an extra-chromosomal element of mainly bacterial cells whereas vector is a vehicle that carries foreign DNA molecules into another cell. Plasmids can also be used…
What is echo sounder and its use? Echo sounding is a type of sonar used to determine the depth of water by transmitting acoustic waves into water. The time interval between emission and return of a pulse is recorded, which is used to determine the depth of water along with…
How does DNA sequencer work? Sequencing employs a technique known as electrophoresis to separate pieces of DNA that differ in length by only one base. … Smaller molecules move through the gel more rapidly, so the DNA molecules become separated into different bands according to their size. What is automated…
How does automated DNA sequencing work to determine the nucleotide sequence of a piece of cloned DNA? Automated DNA sequencing uses a PCR-type reaction to sequence DNA. In PCR sequencing, or cycle sequencing, the template DNA with unknown sequence is amplified by Taq polymerase as any normal PCR reaction. What…
How does aerobic digestion work? Process. Aerobic digestion is typically used in an activated sludge treatment plant. Waste activated sludge and primary sludge are combined, where appropriate, and passed to a thickener where the solids content is increased. This substantially reduces the volume that is required to be treated in…
What does amylase do to starch? Amylases digest starch into smaller molecules, ultimately yielding maltose, which in turn is cleaved into two glucose molecules by maltase. Starch comprises a significant portion of the typical human diet for most nationalities. How does amylase change the result in a starch test? This…
How does ambient temperature affect body temperature? The human body reacts to external and internal changes. Body temperature rises when the external temperature increases but also when the internal temperature increases. Experts consider the normal body temperature to be around 98.6F (37C), but it can vary by up to 0.9F…
How does allosteric regulation of enzymes work? An allosteric site does not bind substrate, but instead binds another molecule that affects the enzyme’s regulation. … When a molecule binds an allosteric site, it alters the enzyme’s shape, or conformation, which then changes how the enzyme functions. What happens allosteric regulation?…
Why air movement is important? Air flowing freely throughout your home helps to regulate temperature, prevent buildup of particles and mold, and it makes breathing easier for everyone in your family. How does ventilation affect thermal comfort? Results show that variable ventilation modes bring a more comfortable indoor thermal environment…
Do air fresheners clean the air? A fragrance in a product is not intended to clean the air or reduce air pollutants. Although some air fresheners make claims of being able to remove odors, disinfect the air, or reduce allergens, these claims may not be possible to verify. Is smelling…
How does blood agglutination occur? Agglutination is the clumping of particles. … When people are given blood transfusions of the wrong blood group, the antibodies react with the incorrectly transfused blood group and as a result, the erythrocytes clump up and stick together causing them to agglutinate. What causes agglutination?…
What does excessive agglomeration lead to? While the existence of cities can only persist if the advantages outweigh the disadvantages, agglomeration may also lead to traffic congestion, pollution and other negative externalities caused by the clustering of a population of firms and people and that this may lead to diseconomies…
How does age affect simple reaction time? Introduction. Adult human reaction times in response to simple tasks slow with age at a rate of 2-6ms per decade 1 3. … These increases in response times have been attributed to changes in both the physical capabilities and the self-selected behaviors of…
Why does cardiac output decrease when afterload increases? The ejection velocity after the valve opens is increased because decreased afterload increases the velocity of cardiac fiber shortening as described by the force-velocity relationship. More blood is ejected (increased stroke volume), which decreases the ventricular ESV as shown in the pressure-volume…
Why are adults not considered to be completely socialize? what are the goals of socialization? … school, work, family: marriage and parenthood; Adults are never considered to completely socialized because there will always be new situations and new roles to learn. At what age does socialization begin? Socialization is a…
How does acid Precipitation affect aquatic life in a lake? Acid rain causes a cascade of effects that harm or kill individual fish, reduce fish population numbers, completely eliminate fish species from a waterbody, and decrease biodiversity. As acid rain flows through soils in a watershed, aluminum is released from…
What is the mechanism of action of Acetylcysteine? Pharmacology and mechanism of action Acetylcysteine is a sulfhydryl compound and acts to increase synthesis of glutathione in the liver. Glutathione subsequently acts as an antioxidant and facilitates conjugation to toxic metabolites, particularly the toxic metabolites of acetaminophen. How does Acetylcysteine work…
What effect does acetylcholine have on the postsynaptic neuron? When a nerve impulse arrives at the nerve ending, acetylcholine stored in vesicles, is released, and binds to a postsynaptic receptor, causing depolarization. What happens to ACh after it is released from the presynaptic membrane? What happens to acetylcholine (ACh) after…
Can acyl CoA enter the mitochondria? After formation in the cytosol, acyl-CoA is transported into the mitochondria, the locus of beta oxidation. Transport of acyl-CoA into the mitochondria requires carnitine palmitoyltransferase 1 (CPT1), which converts acyl-CoA into acylcarnitine, which gets transported into the mitochondrial matrix. How is Acetyl-CoA transported out…
What is abrasion caused by? An abrasion is a type of open wound that’s caused by the skin rubbing against a rough surface. It may be called a scrape or a graze. When an abrasion is caused by the skin sliding across hard ground, it may be called road rash.…
