Answer to Problem 1CA
Correct answer: d. all of the above
Explanation of Solution
Reason for the correct answer:
Option d. is given as “all of the above”.
The digestion process can be defined as the chemical and mechanical breakdown of food, and in addition, the absorption of resulting nutrients. Mechanical digestion refers to the breakdown of large food pieces into smaller pieces without changing their chemical composition. Chemical digestion refers to the breakdown of large nutrients into simpler forms of chemicals. These processes are carried out by the organs of the digestive system.
Hence, the correct answer is option d.
Reasons for incorrect answers:
Option a. is given as “mechanical breakdown of foods”.
One of the functions of the digestive system includes the mechanical breakdown of foods. This system also carries out other functions such as the chemical breakdown of foods and breaking of large food particles into smaller ones. Therefore, option a. is incorrect.
Option b. is given as “breaking large pieces of food into smaller ones without altering”. One of the functions of the digestive system includes the breaking of large food particles into smaller ones. This system also carries out other functions such as the mechanical and chemical breakdown of foods. Therefore, option b. is incorrect.
Option c. is given as “chemical breakdown of foods”.
One of the functions of the digestive system includes the chemical breakdown of foods. This system also carries out other functions such as the mechanical breakdown of foods and breaking of large food particles into smaller ones. Therefore, option c. is incorrect.
Hence, options a., b., and c. are incorrect.
The chemical and mechanical breakdown of foods and breakdown of large food particles into small particles are the functions of the digestive system.

- Molecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?arrow_forwardMolecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forwardMolecular Biology Question A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell.
