The journey of the food through the digestive system will actually digest the food. The rest will be given out as feces.
<h3><u>Explanation:</u></h3>
The digestive system actually consists of digestive tract and Digestive glands. The processes that are associated with digestive system is - ingestion, digestion, absorption, assimilation and egestion.
The food that is taken is first smashed and chewed into a rough bolus by mixing with saliva. The salivary amylase slightly digests the starch into dextrin.
Then the food is engulfed through the oesophagus into stomach. Inside stomach, the food is mixed with an enzyme pepsin and HCl. Pepsin digests the proteins into peptones and peptides. The food is converted into a bolus and transported into duodenum.
In duodenum, there are several enzymes from small intestine and pancreas breaks the fats into fatty acids, proteins into peptides and starch into carbohydrates like glucose. They are absorbed and the undigested substances are left over ad feces.
Answer:
To be sustainable is to be able to maintained at a certain rate. It's to keep things continuous and viable.

Explanation:
also its practically a breeding ground for dangerous diseases, with all the rotting animal bodies, many of them exotic, and not fit for consumption
When a cell is in G2 phase, it has already doubled in S phase its DNA, meaning that for each chromosome we have two chromatids -> 2n(number of chromosomes)×2(number of chromatids per chromosome)=number of chromatids.
If 160 is the number of chromatids on G2 phase of a chicken cell, it means that the cell has 80 chromosomes (2n), and after meiosis, process to form a sperm cell, will only have 40 chromosomes (n).
