There are lots of location that mechanical digestion occurs. But 2 common locations of mechanical breakdown of food (or physical digestion) occur in the mouth and in the duodenum.
Mechanical breakdown of food does not require enzymes, which is different from chemical digestion. Usually, the main function of mechanical digestion is to help speed up the chemical digestion later, usually by increasing the surface area of the food.
In the mouth, we chew the food. This can help increase the amount of surface area of the food we ate so that later on, the chemical digestion that requires enzymes such as amylase or protease will speed up. More enzymes can contact the food.
In duodenum, bile that are produced from the liver helps emulsify fats and lipids into small oil droplets. Again, this action can also help increase the surface area of the lipids so that the digestion of lipids with enzyme lipase would be more efficient. Note that bile is important because only enzyme lipase can digest lipids in the duodenum, so if bile is not produced, fats are hardly digested.
Other types of mechanical digestion may include the churning in stomach, or the squeezing of food in the oesophagus (peristalsis).
The answer is negative controls. These are groups where no phenomenon is probable. They ensure that there is no effect when there should be no effect. Where there are only two possible outcomes, e.g. positive or negative, if the treatment group and the negative control both produce a negative result, it can be concluded that the treatment had no effect. If the negative control group and the treatment group both yield a positive result, it can be inferred that a puzzling variable is involved in the occurrence under study, and the positive results are not only due to the treatment. In other examples, outcomes might be measured as lengths, times, percentages, and so forth.

1. One cell for a Phagocyte is called amoeba.
2. A cell that produces antibodies is called B lymphocytes.
3. A cell which produces histamine in an allgeric response is called antigens.
4. A cell that allows the secondary response to be faster than the primary immune response is called Antigen‐specific T cells.
5. A cell which differentiates to form a plasma cell is called B cells.
6. A cell that destrosy cells which are infected with a pathogen (in cell mediated response is called cytotoxic, helper, and suppressor T cells.

Hello There!
The question you asked is how is the male reproductive system different from other body systems?
The answer is "It isn’t necessary to vital signs."
unlike other body systems, the male reproductive system is not essential for the life of a living organism.
A slide hammer puller. A slide hammer puller can be used to pulll a bearing from a bored hole that is pressed into. They are adjustable with either a collet or puller jaws. To remove the bearing, slide the weight back hard until it hits the flat area on the rear of the puller.
