Answer:

Caso de estudio: El efecto de estresores ambientales sobre el comportamiento animal

- Ejemplo de un tipo de estudio cualitativo: la influencia de estresores ambientales (por ej. niveles anormales de dióxido de carbono atmosférico) sobre el comportamiento en ratones de laboratorio  

- Ejemplo de un tipo de estudio cuantitativo: la influencia de estresores ambientales sobre los niveles de producción de hormonas asociadas a cambios comportamentales en ratones de laboratorio  

Explanation:

Un enfoque cualitativo se caracteriza por el hecho de que la información obtenida durante dicho estudio se agrupa en categorías mutuamente excluyentes. En biología, los estudios de tipo cualitativo generalmente se caen dentro de la dicotomía observacional (es decir, presencia o ausencia del factor en estudio). En el ejemplo arriba citado, es posible obtener datos relacionados a uno o más determinado aspectos comportamentales en los individuos bajo estudio (por ejemplo, presencia o ausencia de signos de irritabilidad) en ratones sometidos a algún estresor ambiental (por ejemplo, niveles anormales de CO2 atmosférico). Por otra parte, en un enfoque cuantitativo, la información se recopila en intervalos obtenidos a partir de operaciones aritméticas (estadística paramétrica). En el ejemplo, los datos obtenidos pueden ser clasificados en intervalos referidos a los niveles hormonales. Esta información resulta útil para determinar si las diferencias en los niveles hormonales entre individuos que se encuentran en presencia del estresor ambiental son estadísticamente significativas respecto al grupo control (individuos desarrollados en un ambiente con niveles normales de CO2 atmosférico), y de este modo concluir si el estresor ambiental puede o no modificar variables comportamentales. Los estudios cualitativos permiten el uso de variables independientes las cuales son clasificadas como cualitativas (discretas).

explain why the following statements are false. a. feedback inhibition is defined as a mechanism of down-regulating enzyme activ
lyudmila [28]

False. Feedback inhibition occurs when an enzyme acting early in a pathway is inhibited by the accumulation of a product late in the pathway

<h3>What is inhibition ?</h3>

Inhibition is the conscious or unconscious restriction or restraint of a process or behavior, especially of urges or wants. The ability to inhibit oneself from acting on some impulses, such as the desire to hit someone in a fit of rage, and to delay the satisfaction of pleasurable activities allows one to perform vital social functions. When two desires are perceived that are in conflict, conscious suppression often occurs in daily life (e.g., the desire to eat a rich dessert versus the desire to lose weight).

According to psychoanalytic theory, inhibition serves as a mediator between the id and the superego, or conscience, and is largely unconscious (primitive desires). The socially imposed inhibitions known as taboos, such as those prohibiting incest or murder, are elevated to the level of moral prohibition.

change in temperature and pH can change the shape of the enzyme and They can break down the reactants

Temperature. Higher temperatures typically result in faster rates of reaction, whether they are enzyme-catalyzed or not. The chemical bonds in the active site, however, can be impacted by temperature changes that are either too high or too low and make them less able to bind substrates. Extremely high temperatures (over 40 degrees Celsius may cause animal enzymes to denature, losing their form and activity)

pH can also affect enzyme function. The acidic or basic characteristics of active site amino acid residues are frequently crucial for catalysis. These residues can be impacted by pH changes, which can make it difficult for substrates to bind. Like with temperature, certain pH ranges (acidic or basic) can cause enzymes to denature. Enzymes function best within these pH ranges.
