Trace what happens to a piece of bread as it enters the mouth to the large intestine. Be sure to mention each organ of the digestive system and what happens to the bread in each part.( This is an essay question )put in high school level)

The mechanical digestion begins with the with and the tongue whch breaks the bread,press it staging the soft palate Chemical digestion follows with the saliva-enzyme salivary amylase. The enzymes acts on starch in  the bread and converts this to Maltose.A diassacharides , and oligosaccharides This ends CHO digestion in the mouth.

The digesting bread   is push by waves of contraction of the horizontal and vertical muscles of the oesophagus.This wavelike contractions is called Peristalsis.

This is push down into the stomach through the opening of the upper sphincter.In the stomach the pH of the amylase enzyme in the bread now called chyle is reduced(neutralized) by the HCL of the medium.No digestion occurs in the stomach.

In the small intestine is the enzyme  pancreatic Maltase,secreted from the pancreas.This enzyme catalysis the hydrolysis of the maltose ( diasaccharides,) to  some monosaccharides subunits.At this stage the digesting bread is called chyme,with its maltose content.

Still in the small intestine maltase(from the epithelial brush borders of the small intestine) converts the hydrolysis of maltose to the sub units of glucose,fructose, and galactose,making the end of CHO digestions in the small intestine.

The large intestine is for absorption of water and storage and removal of undigested foods from the body.It is made up of the cecum, colon, rectum and anus.As unwanted food passes through this.,massive water absorption occurs, it contents and structure is change to stool as  it escapes through the anus, as faeces.

Explanation:

ans.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
