The difference between chemical and mechanical digestion is:
Simple:
Chemical digestion= Process that breaks large food parts into small molecules that can be taken in by cells.
Mechanical digestion= Process of breaking down food into smaller pieces by chewing and smashing.
More advanced:
Mechanical Digestion - Food is crushed and liquefied by the teeth, tongue, and peristaltic contractions (waves of involuntary muscle contraction) of the stomach and small intestine. This creates a greater surface area for the digestive enzymes to work upon.
Chemical Digestion - Many glandular structures, dispersed throughout the body, are involved in breaking food into simple molecules that can be absorbed. In the mouth, the salivary glands produce saliva, which both lubricates food and begins the process of starch digestion. Saliva contains salivary amylase (ptyalin), an enzyme that digests starch to maltose (a disaccharide). As food leaves the mouth, the esophagus conducts it to the stomach via the cardiac sphincter by means of peristaltic waves of smooth muscle contraction.

Compare and contrast mechanical digestion and chemical digestion?
Mechanical Digestion (or physical digestion) is more about the mouth. It's chewing, biting, breaking down, and sofening the food. This is why its called "Mechanical" Digestion.Mechanical digestion involves the pulverizing and crushing of food particles, usually by chewing. Chemical digestion occurs through the secretion of digestive juices.
Compare mechanical digestion to chemical digestion?
mechanical digestion - chewing, mixing, churning chemical digestion - breakdown of fat, carbohydrate and proteins by specific enzymes (lipases, amylases, and proteinases respectively)
Compare mechanical and chemical digestion?
actually the mechanical digestion takes place first in our body that is the whole process of digestion we normally study. where the whole process is of getting things like glucose, minerals, proteins etc.. but the chemical digestion takes place at the cellular level means in the cells that is the break down of glucose in getting energy to work or metabolism of the cells
Compare digestion of invertebrate animals to higher animals?
Invertebrates have a much simpler digestive system, in some it is nothing more than a straight tube from one end to the other.
How does the energy involved in nuclear processes compare to that of chemical interactions and mechanical processes?
Nuclear energy vastly overshadows the energy from chemical and mechanical energy, because nuclear energy is based on the release of binding energy, which lies at the core of everything. It is the Strong Atomic Force.
Is computer science better now?
no , not yet . and it takes some time to recover. compare to computer science it is best to choose mechanical or civil or chemical
How does actual mechanical advantage compare with ideal mechanical advantage?
The actual mechanical advantage is usually less, due to losses.
Which is higher profession mechanical engineer or architect?
Architect is higher Profession as compare to Mechanical Engineer.
Compare and contrast mechanical weathering and chemical weathering?
Mechanical weathering provides fresh surfaces for attack by chemical processes, and chemical weathering weakens the rock so that it is more susceptible to mechanical weathering.
How does the ideal compare with the actual mechanical advantage?
The actual mechanical advantage is usually less, due to losses.
Compare and contrast chemical weathering and mechanical weathering?
Mechanical weathering is taking a big rock and breaking it down to small rocks by releasing pressure, freezing and thawing (water and ice), animal action, plant growth and abrasion. Chemical weathering is when a rock loses it shape but STILL IS MADE OF THE SAME METRICAL. Chemical weathering uses water, oxygen, carbon dioxide, living organism, and acid rain.
What two quantities does mechanical advantage compare?
Input and output (of energy)
