Answer:enzymes
Explanation:during digestion, food is broken down by chewing in the mouth.enzymes also acts on foods to reduce them into simpler constituents.enzymes acts on food in the mouth, stomach, intestine etc.
Enzymes that acts on proteins helps to break the peptides bonds present in proteins.they break up the polypeptide chains into amino acids .An example is trypsin .the conditions necessary for these enzymes to acts may be specific.some require acidic environment while others require basic environment.pepsin for example requires stomach hydrochloric acid to be converted from it's inactive form, pepsinogen.
The resultant Amino acids are then absorbed in the small intestine
Mitotic division in onion root cells:
- Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
- Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
- Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
- Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.
Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.
