They are called ENZYMES.
Enzymes speed up the rate at which the digestion process occur so that the nutrients in the food can be absorbed by the body and used for the development of the body.
Afferent nerve fibers carry signals from the somatic receptors to the posterior horn of the spinal cord or to the brainstem. So i beleive it is 4 but not too sure. Hope this helped a bit (:
Answer:
Option B. a health problem due to the concentration of hydrogen ions (H+) being 10X higher than normal in your body is correct answer.
Explanation:
When lungs are not able to remove carbon dioxide produced by blood it results in decrease in pH of blood (blood become more acidic). This condition is called respiratory acidosis. However, body has the ability to balance ionic concentration. (See attached image for more explanation)
The bacterial genes are usually found in operons. Each operon comprises regulatory sequences of DNA that function as binding sites for regulatory proteins, which inhibit or encourage transcription. The regulatory proteins usually combine with small molecules that can make the protein inactive or active by altering its tendency to combine with DNA.
The four combinations of active or inactive regulatory proteins, which could be observed at any time in the cell are:
1. Active repressor, active activator,
2. Active repressor, inactive activator
3. Inactive repressor, active activator
4. Inactive repressor, inactive activator
Answer:
A. Prokaryotic
