Cephalochordata is the subphylum that retains all chordate characteristics, even in the adult forms.
Answer:
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.
If Transcribing the DNA codon it would have to become MRNA.
Answer:
- Peristalsis.
Explanation:
- Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.
