<span>When ozone forms near the ground, it is known as a secondary pollutant. This is because it is the result of two primary pollutants reacting to create a new substance. The reaction between the primary pollutants is airborne and then the resultant ozone settles near the surface of the ground.</span>
Answer:
In Anfinsen's ribonuclease A renaturation experiment,he wanted to show that protein folding entirely resides within the amino acid sequence of protein.
Explanation:
He used ribonuclease A as a model and removed urea and 2ME from the folding solution.Under these condition, ribonuclease A regains it's biological activity.
This refolding occur in in vitro conditions.
This experiment discover an enzyme called protein disulfide isomerase(PDI) which catalyze the reduction of incorrect dissulfide bonds.This also helps in trapping protein in an incorrect conformationso that it can un fold and try agin.
This PDI plays important role in proper folding,and the active site of this enzyme have disulfide.
The emulsion test<span> is a method to determine the presence of lipids using wet chemistry. The procedure is for the </span>sample<span> to be suspended in ethanol, allowing lipids present to dissolve (lipids are soluble in alcohols). The liquid (alcohol with dissolved fat) is then decanted into water.</span>
Administration of testosterone should lead to male mating behavior in an animal only if The requisite sexually dimorphic nuclei are sufficiently masculinized.
The main sex hormone and anabolic steroid in guys is testosterone. In humans, testosterone is essential for the growth of the testes and prostate, as well as for the promotion of secondary sexual traits including increased bone and muscle mass and the development of body hair. Through territorial aggression, wooing rituals, and mate-guarding behavior, high testosterone levels have been found to improve mating effort.
The preoptic area of the hypothalamus, where the sexually dimorphic nucleus -POA is situated, regulates male sexual behavior. Snake, reptile, avian, rodent, ungulate, and primate male-typical copulatory activity is reduced by large lesions in the preoptic region.
