Answer:
Common sources of error include instrumental, environmental, procedural, and human. All of these errors can be either random or systematic depending on how they affect the results. Instrumental error happens when the instruments being used are inaccurate, such as a balance that does not work (SF Fig

Options:
A. The enzyme lactase will speed up the breakdown of lactose in the small intestines.
B. Reactions that involve enzymes require more energy than reactions without enzymes.
C. The enzyme lactase will slow down the breakdown of lactose in the small intestines.
D. Lactase will require more energy to break down lactose, and less energy is required if it is not present.
Answer:
A. The enzyme lactase will speed up the breakdown of lactose in the small intestines.
Explanation:
A. The enzyme lactase will speed up the breakdown of lactose in the small intestines. - this is true. Lactase is an enzyme that catalyses the breakdown of lactose. This means it greatly reduces the activation energy required for the breakdown of lactose, and the reaction will happen quicker.
B. Reactions that involve enzymes require more energy than reactions without enzymes. This is false. Reactions that involve enzymes require less energy that reactions without
C. The enzyme lactase will slow down the breakdown of lactose in the small intestines. This is false. It will speed it up
D. Lactase will require more energy to break down lactose, and less energy is required if it is not present. This is false, more energy is required if it is not present
Answer:
What are DNA vaccines? - Biologybiology.kenyon.edu
Explanation:
DNA vaccines are third generation vaccines. They contain DNA that codes for specific proteins (antigens) from a pathogen. The DNA is injected into the body and taken up by cells, whose normal metabolic processes synthesize proteins based on the genetic code in the plasma that they have taken up.
