hope it gonna work...✌️✌️✌️
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.
This question is long and it is late here, but I can help you understand it. DNA consists of 4 nucleotide bases: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). When DNA is transferred to RNA, you use the complimentary nucleotide base to each as follows:
Adenine changes to Uracil (replaces Guanine in RNA)
Thymine changes to Adenine
Cytosine to Guanine and vice versa
So, the DNA code ‘TAC’ will have the mRNA complimentary strand of ‘AUG’. When changing mRNA to tRNA, you do as follows:
Change A to U
U to A
C to G
G to C
It’s that simple. Then, to change to amino acids, you need to use the codon chart attached (a codon is 3 nucleotide base pairs)
For example, mRNA codon AUG codes for the amino acid Methionine. Hope this helps.
