Answer:

3 characteristic

Explanation:

1- it contains sulfur when bacteria found sulfur in the media then it produces H2S (hydrogen sulfate). It causes the blackening of the media which acts as an indicator that bacteria can produce H2S.

2- Indol is the second characteristic. If bacteria is indol positive than it changes color from yellow to pink when the reagent is added.

3- Motility: if bacteria are motile than it's motility is easily visible in the media.

Dynamic regulation is required for maintaining homeostasis.Explain how a cellular mechanism that regulates the quantity of a bio
Troyanec [42]

The homeostasis of the human body works like a machine set at a particular standard. If the factors deviate from the standard values, the homeostatic mechanism come into action.

For example, if a cell requires certain protein, the respective genes get a signal and get activated. The cell start synthesizing the protein and when sufficient amount is made, there is a feedback loop, which allows the same protein to stop the synthesis as well. A lot of organs and cellular systems are involved in regulating the synthesis of this protein.

This is similar to the cooling system. If we set the temperature of the cooling system to certain degree, it will start cooling the room till the required temperature is reached. As soon as the temperature is acquired, the system cut-off automatically and the required temperature is maintained.

En un experimento, se prueba el efecto de cambiar el pH en una reacción enzimática. ¿Cuál podría ser una variable dependiente en
stich3 [128]

Answer:

velocidad de reacción

Explanation:

Las enzimas son proteínas que catalizan reacciones, es decir, aumentan la velocidad de reacción. Si se quiere evaluar el efecto de cambiar el pH en una reacción enzimática, se debe realizar la reacción a distintos valores de pH e ir midiendo la velocidad de reacción. Por lo tanto:

pH: variable independiente

velocidad de reacción: variable dependiente

La velocidad de reacción podría medirse a través de la cantidad de producto que se forma por unidad de tiempo, o a través de la cantidad de sustrato que se consume por tiempo.
