Answer:
A. INACTIVE PRECURSOR OF THE ENZYME PEPSIN THAT DIGESTS PROTEINS IN THE STOMACH.
Explanation:
Pepsinogen is the inactive precursor of pepsin produced by the chief cells of the stomach lining. The stomach walls are lined by majorly two types of cells; the chief and the parietal cells. Chief cells secretes pepisinogen and parietal cells secrete hydrochloric acid in the stomach lining. The chief cells upon the signals of increased protein substance in the stomach produces pepsinogen which upon it release, it is activated to the active enzyme Pepsin by the hydrochloric acid from the parietal cell. Hydrochloric acid provides the acidic environment needed for the action of pepsin in the stomach. The pepsin begins the digestion of proteins into small amino acids in the stomach,
Answer:
The prevention of loss in the most top layer of soil from the erosion or maybe prevention of deducted fertility
Answer:
the act of urinating.
Explanation:
the discharge of urine from the bladder; urine from the kidneys is passed in spurts every few seconds along the ureters to the bladder, where it collects and later is passed to the outside via the urethra.
Lysogenic cycle commonly
occur in eukaryotes and is a process where viral DNA or RNA is integrated into
the host cell as a new set of genes called prophage. However, the Viral DNA
becomes the part of the cells genetic materials.
Steps involves during
lysogenic cycle:
1) Cell enters the viral genome
2) Integration of the viral genome into the host cell genome
3) Viral chromosome is copied by the host cell using DNA
polymerase
4) Cell division occurs and transfers of virus chromosomes
to the daughter cell
5) Any trigger in virus will result into detachment of viral
genome from the host cell’s DNA.
