If a DNA strand contains 26% thymine, what percent adenine will there be in the
same DNA molecule?
Hint: use Chargaff's Rules
24%
27%
26%
23%
Answer:
26%
Explanation:
Adenine and Thymine are pairs. Therefore, they must have the same amount.
It must always equal 100% and base pairs always have the same amount. So in this case Adenine and Thymine would be 26% and Guanine and Cytosine would be 24%.
Test question: If a DNA strand has 10% Guanine how much Adenine would there be?
Answer: G-10, C-10, A-40, T-40= 100%

People’s choices can have a positive or negative effect on their health. Describe one positive choice and one negative health choice a person could make. Be sure to explain how each could impact an individual’s health and, if applicable, the health of others.
People nowadays try to live a healthier lifestyle. The positive and negative choices depends on some aspects. For instance, a person with a normal weight or thin can be unhealthy . Health also includes the good amount of nutrition and exercise not only the weight. A good choice a person can make is exercise more and intake good amounts of nutrition. A bad choice is not exercising and not having adequate intake of nutrition. Some people tend to lose weight by quiting some nutrients which will have a bad effect on their health since all the nutrients are important for the body and avoiding some nutrients can cause deficiency. The best thing to do is diet on calories, a type of diet from which you can eat anything(all types of food including vegetables and fruits ) but measure your calorie intake , with this a person has a higher chance of losing weight and being healthy. Exercise too is an essential factor needed for a healthy lifestyle. If a person has a lifestyle which they need to move alot(jobs including sports etc) then you can say its enough but if not a person must do exercise at least twice or more a week for better health. Quitting smoking and drugs of course has a good effect.

Enzymes speed up chemical reactions. Which statement correctly identifies the function of the enzymes involved in DNA replication?
A: Helicase adds hydrogen bonds to the template strand DNA polymerase breaks nitrogen bases
B: Helicase adds nitrogen bases to the template strand, DNA polymerase breaks hydrogen bonds
I
C : Helicase breaks nitrogen bases in the template strand. DNA polymerase adds hydrogen bonds
D : Helicase breaks hydrogen bonds in the template strand DNA polymerase adds nitrogen bases
Answer:
D: Helicase breaks hydrogen bonds in the template strand, DNA polymerase adds nitrogen bases
Explanation:
DNA replication is the process whereby DNA content is duplicated. This process of DNA replication is carried out with the aid of certain enzymes. Two of those important enzymes as stated in this question are DNA Helicase and DNA polymerase.
- DNA Helicase is the enzyme that breaks the hydrogen bonds that holds the two DNA strands in the molecule together. This separates the double-stranded DNA into two single strands.
- DNA polymerase is another enzyme that which carries out the nucleotide synthesis. DNA adds nitrogen bases to the new DNA strand based on what it reads on the DNA template
Which of the following is most likely an example of genetic drift resulting from the founder effect?
Answer:
An example of genetic drift resulting from the founder effect, of the available answers listed below, would most likely be a situation in which a population commonly expresses traits that are otherwise rare in the species. An example of this might be an animal with longer limbs than other members of the same species - there have been real-life examples of this studied with lizards.
Explanation:
Emission lines are lines that are made when wavelengths of light are given off by cooling gases.
O True
O False
Answer:
Its FALSE on edge
Explanation:
When cooling gases emit light wavelengths, lines known as emission lines are created. The first people to notice constellations were the ancient Romans and Greeks.
What Emission lines that are made when wavelengths light?Monochromatic light has a single wavelength and is generated by lasers, which exploit transitions between two atomic energy levels to generate light with an extremely restricted range of wavelengths.
While emission lines refer to the lines of light produced by burning hot gas, absorption lines refer to the tendency of cool ambient gas to absorb the same lines of light.
Some light at specific wavelengths is scattered when it travels through the atmosphere's gas, producing darker bands.
Therefore, It is false that Emission lines are lines that are made when wavelengths of light are given off by cooling gases.

The browning of potatoes on contact with oxygen is caused by the enzyme reaction depicted above. Which of the following could increase the rate of this reaction?
A. Adding more catechol oxidase
B. Adding more benzoquinone
C. Reducing the amount of catechol
D.Reducing the amount of catechol oxidase
Pls help! P.S. you may or may not have to click on the picture to see all of it. Thank you.
Answer:
I think it is adding catechol oxidase
Explanation:
This is because more enzymes are able to take in more substrates, or reactants more quickly, therefore increasing the speed of the reaction.
Hope this helps!
Answer:
he is correct it is adding catechol oxidase
Explanation:

30 grams of ammonia (NH3), nitrite (NO2-), and nitrate (NO3-) are added to a soil sample.
Predict whether these concentrations would increase, decrease, or stay the same if nitrite-nitrifying bacteria were added to the sample.
If 30 grams of ammonia (NH3), nitrite (NO2-), and nitrate (NO3-) are added to a soil sample and nitrite-nitrifying bacteria are added, the concentration of the nitrate would increase, that of the nitrite would decrease, while that of ammonia would remain the same.
The process of converting ammonia to nitrate, also known as nitrification occur in two stages:
The conversion of ammonia to nitrite by ammonia oxidizing bacteria.The conversion of nitrite to nitrate by nitrite-oxidizing/nitrifying bacteria.Now, if nitrite-nitrifying bacteria is added to the soil sample above, it means that only the nitrite would be converted to nitrate. The bacteria will not be able to oxidize ammonia.
Hence, some of the nitrite would be converted into nitrate leading to the reduction in the concentration of the former, and an increase in the concentration of the latter. The concentration of ammonia will remain unchanged.

Watch this video about the stresses on the body caused by carrying heavy backpacks. Then design an
investigation about the effect of carrying backpacks on students' health using these steps of the scientific method:
• make observations or inferences
• ask questions
• construct hypotheses and make predictions
• test hypotheses
• analyze results
Your investigation can address any question you have about backpacks and student's health that you choose.
PLATO helppp
Answer:
Make observations or inferences: In school, most students carry a backpack. Students frequently complain that their backpacks are heavy or hurt their backs.
Ask questions: Do students who carry heavier backpacks report more pain than students who do not?
Construct hypotheses and make predictions: Students who carry heavier backpacks are more likely to experience pain in their back at the end of the school day.
Test hypotheses: Get a sample of students in the school to help with the experiment. All students in the experiment would be students from the school and have no known back conditions. Then weigh the students’ backpacks, and ask the students if they have back pain at the end of the day.
Analyze results: Record the data in a table, and then organize the information by the weight of the backpacks. Group the backpack weights in five-pound intervals (five pounds, ten pounds, etc.) and use a bar graph to show the yes and no responses to the pain question for each student.
