Answer: A knockout mutation in which the gene is "erased" through a nonsense mutation. In this way, the gene that codes for insuline would be eliminated, and no insuline would be produced.
Explanation:
Type I diabetes is a chronic disease in which no insulin or too little insuline is produced by the pancreas. There are many factors that can trigger Type I diabetes, including genetics and certain viruses. Although Type I diabetes is more likely to appear during childhood or adolescence, it can also begin in adulthood. It is a disease that cannot be cured but can be treated, and treatment focuses on controlling blood sugar levels with insulin injections and a controlled diet.
Insulin is produced by beta cells in the islets of Langerhans of the pancreas. It is a hormone used to allow glucose to enter the cells to produce energy, helping to transport the sugar from the blood to the other tissues of the body. So, through glycolysis and cellular respiration, the necessary energy is obtained in the form of ATP.
So, we could consider that the gene coding for insulin is not working properly or not working at all. So, a mutation that would mimic Type I diabetes is a knockout mutation in which the gene is "erased" through a nonsense mutation (a point mutation in DNA that results in the appearance of a premature termination codon, so the synthesis of the protein ends earlier, it is not completed). In this way, the gene that codes for insuline would be eliminated, and no insuline would be produced. This type of mutation can be achieved in a laboratory and rhis results in organisms that do not express the gene in a specific tissue or in the whole organism.

Determine the type of inhibition that has occurred in a first order Michaelis-Menten enzyme catalyzed reaction that has yielded the following data. Vi is the velocity in the presence of inhibitor, V is the velocity when run without inhibitor and [S] refers to the substrate concentration. [S] V Vi 3.333 0.283 0.055 1.000 0.260 0.054 0.400 0.222 0.052 0.263 0.197 0.051 0.179 0.171 0.049
Answers
Answer:
competitive inhibition
Explanation:
Given in the first order [tex]\text{Michaelis-Menten enzyme catalyzed reaction}[/tex].
[tex]$V_i$[/tex] = velocity in the presence of the inhibitor
V = velocity when run without the inhibitor.
S = substrate concentration
We need to plot a curve for [tex]$\frac{1}{[V]}$[/tex] vs [tex]$\frac{1}{[S]}$[/tex] and a second plot of [tex]$\frac{1}{[V_i]}$[/tex] vs [tex]$\frac{1}{[S]}$[/tex]
By plotting the curve we see that the slope and the intercept are not the same for the two curves.
And also, the [tex]$V_{max}$[/tex] for the second curve with the inhibitor is lower than the first curve.
Therefore, the inhibition type would be competitive.

Some of the organic material manufactured in the estuarine communities is exported to other ecosystems. What type of ecosystems receive this material
Answers
Answer:
Coastal and open-water ecosystems
Explanation:
Organic material manufactured in estuarine communities is exported to coastal and open water ecosystems. This organic material is very beneficial to these ecosystems as it allows many nutrients to float in the changing tides. These nutrients are a very rich food source for coral reefs and kelp forests. Furthermore, these nutrients arrive in the ecosystem in the form of debris that can serve as breeding grounds for very important organisms in the region and that serve to maintain the food chain.
Which of the following statements about the energy needs of cells is false?

A the most usable energy for cells comes from the rapid combustion of glucose
The statement 'the most usable energy for cells comes from the rapid combustion of glucose' is FALSE (Option 1).
Glucose is a simple carbohydrate that provides a rapid energy source to the cells.In animals, glucose is used to produce glycogen, which is a complex carbohydrate that provides a long-term source of energy.All metabolic reactions in a cell depend on the presence of activation energy, which generally is provided by ATP, the energy coin of the cell.In conclusion, the statement 'the most usable energy for cells comes from the rapid combustion of glucose' is FALSE (Option 1).

The correct answer is - a- They convert energy from the sun to chemical energy.
Explanation:
Producers in any food web or ecosystem are the organism that can produce the food and energy on their own. Normally these organisms are green plants that can perform photosynthesis in order to produce chemical energy from light energy that comes from the sun.
Producers not only provide food and energy to themselves but also provide food and energy to each trophic level directly or indirectly. Producers are present at the base of the energy pyramid.

Melanin is responsible for black colour of hair.
Explanation:
Hair is black in colour because it is determined by the amount of a pigment present in hair is called melanin. If eumelanin which is a type of melanin, present in hair, it gives people black or brown hair. If the receptor is not activated or is blocked in the hair, then melanocytes make pheomelanin instead of eumelanin and then the black or brown hair colour did not occurs so we can conclude that melanin is responsible for black colour of hair.
Super saturated solutions are used to make rock candy. Please describe how the crystals are formed, be sure to use the terms Solute and Solvent.
Answers
Answer:
Once the solution cools, it now has more solute than it normally could have, and this is called a supersaturated solution. Once a solution becomes supersaturated, it wants to crystallize the excess solute. The solute will form crystals on any surface. In our case the surface is a string, and we are using a lifesaver candy as our “seed.”
Explanation:
Rock candy is a type of candy made by growing sugar crystals on a string or stick.
Why are Super saturated solutions used?Super saturated solutions are often used to make rock candy because they contain more solute (sugar) than the solvent (water) can normally dissolve at a given temperature.
The first step in making rock candy is to heat water in a saucepan and add sugar to it. The sugar dissolves and forms a solution as the water heats up. After that, the solution is heated until it is completely saturated.
This occurs because the super saturated solution is unstable, and the excess solute (sugar) in the solution wants to escape and form crystals.
As time passes, more sugar dissolves from the solution and adheres to the crystals on the string or stick, causing them to grow larger.
The process is repeated until the crystals reach the desired size or until all of the excess solute has been removed from the solution.
Thus, preparing a super saturated solution of sugar and water, then dipping a string or stick into the solution and allowing the excess solute to come out of the solution and form crystals on the string or stick, is the process of making rock candy.
