The flow chart for the cortisol steroid hormone is as follows:

1. Cortisol passes through the plasma membrane into the cytoplasm.

2. Cortisol receptor complex form in the cytoplasm.

3. Cortisol receptor complex enter the nucleus where it binds to gene.

4. Cortisol receptor complex acts as transcription factor.

5. The tranacribed mRNA is translated into specific protein.

Explanation:

Cortisol is small which is hydrophobic steroid hormone which has the ability to move through the plasma membrane of the cells. In the target cells the cortisol binds with the intracellular receptor protein of the cytoplasm which further forms a hormone receptor complex. The hormone receptor complex further moves into the nucleus ad hence acts as a transcription factor which gets bind to the specific gene and thus, activates the transcription into mRNA. The mRNA which is generated subsequently translated into some specific proteins. Proteins which has been produced with response to the cortisol signal function to the stress response.

A string of lights in a series circuit is not working. Which of the following is most likely the cause?
Talja [164]

Answer:

B. a light bulb burned out and "closed" the circuit.

Explanation:

Unscrew one bulb. If the other bulbs turn off, it is a series circuit. A light bulb glows when electrons flow through it. As the electron flow increases, the brightness increases.

When lights are attached in parallel, each light is on its own circuit to the power source. If one filament burns out, it has no effect on the remaining lights, as they each continue to be in a closed circuit with the power source.
