In the past, diabetics used horse or cow insulin
to control their glucose levels. Today, as a result
of genetic engineering, human insulin can be
synthesized by bacteria. State one advantage
for a person with diabetes to receive genetically
engineered insulin rather than insulin taken
from a horse or cow. [1]
Answer:
Genetically engineered insulin is actually human insulin and is less likely to be rejected by the person.
Explanation: Hope this helps
One advantage for a person with diabetes to receive genetically engineered insulin rather than insulin taken from a horse or cow is that human insulin produced by bacteria is less likely to cause an allergic reaction.
Why animal based insulin bad?When animal insulin was used, some people with diabetes developed an allergic response to the foreign protein, causing discomfort and making the treatment less effective. Genetically engineered human insulin produced by bacteria is identical to the insulin produced by the human body, reducing the likelihood of an allergic reaction and making the treatment more effective.
Additionally, genetically engineered insulin can be produced in larger quantities, at a lower cost, and with greater consistency than animal-derived insulin.

According to the operon model, for the synthesis of an inducible enzyme to occur, the:.
The operon model explains the regulatory system of the gene expressions in the bacteria. An inducible enzyme will be synthesized if the substrate binds to the repressor. Thus, option B is correct.
What is the operon model?
An operon model is the representation of the genes that are closely related and is the regulation of the genetic mechanism in the bacteria. They consist of the structural gene, an operator, and a promoter.
The inducible enzyme in the operon model is produced if the substrate binds to the repressor. The substrate act like an inducer to promote the transcriptional process by inhibiting the activity of the repressor.
The inhibited repressor will not be able to bind the operator and hence RNA polymerase will be free to move and complete the process of transcription in bacteria and viruses.
Therefore, the substrate binds to the repressor so that an inducible enzyme is produced.

Blood must be maintained at a fairly constant pH between 7.35 - 7.45. One of the principal buffers responsible for doing this consists of carbonic acid in equilibrium with bicarbonate ions. If you breathe too deeply or rapidly, a condition known as hyperventilation may occur in which some muscles are temporarily paralyzed because the pH of the blood becomes too high.
Explain why the pH changes in this way and why the condition can be corrected by breathing in a paper bag.
Answer:
The most important way that the pH of the blood is kept relatively constant is by buffers dissolved in the blood. Other organs help enhance the homeostatic function of the buffers. The kidneys help remove excess chemicals from the blood, as discussed in the Kidney Dialysis tutorial.

Which complex carbohydrate has 3 to 10 simple sugar units and cannot be broken down by the body's digestive enzymes
Oligosaccharides are complex carbohydrates that have 3 to 10 simple sugar units and cannot be broken down by the body's digestive enzymes. They are complex carbohydrates.
Oligosaccharides, complex carbohydrates and enzymesOligosaccharides are complex carbohydrates composed of three or more monosaccharides (e.g., glucose and fructose) or the union of two or more disaccharides (e.g., lactose).
Humans cannot digest these oligosaccharides because we don't have digestive enzymes such as ⍺-galactosidase, thereby they cannot be hydrolyzed.
Complex carbohydrates are in turn long chains (either branched or unbranched) of monosaccharides linked by glycosidic bonds.
A well-known example of complex carbohydrates (polysaccharides) is starch, which is composed of many subunits of glucose.
Enzymes that break down complex carbohydrates must have the ability to break glycosidic bonds.
