Answer:
The components of he respiratory system conduct air to the lungs ,such as the trachea (windpipe) which branches into smaller structures called Bronchi . The process of breathing (respiration) is divided into two distinct phases , inspiration (inhalation) and expiration (exhalation).
Explanation:
They do not have lungs. They have gills tat help them get the oxygen out of the water around them.
A covelant bond consists a shared electron
Explanation:
In the nucleus
The DNA can be found in the Nucleus
Answer:
The prime function of the GTPase activity of the G-alpha protein is to perform the hydrolysis of the attached guanosine triphosphate or GTP. Upon combination with the GTP, the G-alpha protein becomes activated, and when hydrolysis of GTP takes place to guanosine diphosphate or GDP, the G-alpha subunit becomes inactivated.
Therefore, the activity of the GTPase provides the G protein-coupled signaling mechanism's regulation. In case, if the mutation takes place within the gene encrypting the G-alpha subunit, then the inhibition of GTPase activity occurs, which would eventually result in the following outcomes:
1. The stimulation of the signaling pathway may take place for a prolonged time duration, eventually causing an unwanted differentiation of the cell.
2. There would be a spontaneous enhancement in the concentration of cyclic-AMP within the cell.
3. The activation of the G-alpha subunit would take place for a prolonged time duration.
