Answer: to start what cycle
Explanation:
Answer:
Vertebrates contain nervous system which is highly specialized organ.
Explanation:
The nervous system is the complex system in the vertebrate body which is composed of central nervous system that contain brain,spinal cord and peripheral nervous system which contain cranial nerve, spinal nerve,involuntary nerve etc.
The nervous system contain neurons that mainly transmit signal to the different parts of the body.
The peripheral nervous sytem contain somatic and visceral part.
The grey matter and white matter are the 2 areas in vertebrate nervous system.
<span>Norepinephrine uses the Second
Messenger System, which means, cells signal to each other what molecules have
been released that will trigger a physiological reaction. </span>
<span>
This phenomenon is activated after the ligand (ion or molecule) is bonded to its receptor
(protein molecule), creating a variation that causes a chain-reaction, that will
finally activate the Second Messenger. The latter will activate intercellular
molecules that will be able to control the cell’s activity. </span>
answer: 2) sequence of building blocks of a protein found in a cell.
Just random FYI:
- it is a mutation, that is generally not looked upon as being severe or detrimental to the person
-by changing the base by either adding or deleting from a protein strand will cause the protein to be useless
-frameshift mutation deals with DNA sequence being shifted. For example: a DNA strand looks like a ladder. If one of the rungs on the ladders gets skipped and the next ladder rung gets the code that the previous rung should have gotten, then that is what a frameshift mutation is. Hopefully that makes sense. It's easier to explain if there was a picture.
there are other types of mutation but I won't get into them.
Hopefully this helped and good luck.
Answer:
Airways diameter can influence the airflow resistance.
Explanation:
Airflow resistance follows the same principle followed by the airway resistance. This is the resistance offered during the pulmonary blood flow.
Airways diameter affects the airflow resistance. If the diameter of airway is increased, the airflow resistance decreases and air can flow easily in the body. The decrease in the airway diameter (dilution) increases the airflow resistance of the blood artery.
