measure the hormones consistently detects the levels at 10 points lower than the a (

Answers

Answer 1

Answer:

The correct answer is - accurate.

Explanation:

Systematic measurement errors take place when there is a consistent inaccuracy found in the result of the measurement. In the given case here is consistent 10 points lower than the actual value of hormones produced in the mice. the tool that is measuring the level of the hormones in the mice is showing systematic error and measurements are not accurate.

Thus, the correct answer is - accurate.

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%

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

Answers

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

HELPP!! Describe how the enzyme transforms the substrate. Include in your answer the vocabulary terms: substrate, active site, enzyme, product(s).

Answers

A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.

Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.

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.

Answers

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.

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.

Answers

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.

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.

Then the winds, the hotand the cold, especially such as are common to all countries, andthen such as are peculiar to each locality. We must also considerthe qualities of the waters, for as they differ from one another intaste and weight, so also do they differ much in their qualities.In the same manner, when one comes into a city to which he is a stranger,he ought to consider its situation, how it lies as to the winds andthe rising of the sun; for its influence is not the same whether itlies to the north or the south, to the rising or to the setting sun.These things one ought to consider most attentively, and concerningthe waters which the inhabitants use, whether they be marshy and soft,or hard, and running from elevated and rocky situations, and thenif saltish and unfit for cooking; and the ground, whether it be nakedand deficient in water, or wooded and well watered, and whether itlies in a hollow, confined situation, or is elevated and cold; andthe mode in which the inhabitants live, and what are their pursuits,whether they are fond of drinking and eating to excess, and givento indolence, or are fond of exercise and labor, and not given toexcess in eating and drinking. ----------------------------------------------------------------------PART 2From these things he must proceed to investigate everything else.For if one knows all these things well, or at least the greater partof them, he cannot miss knowing, when he comes into a strange city,either the diseases peculiar to the place, or the particular natureof common diseases, so that he will not be in doubt as to the treatmentof the diseases, or commit mistakes, as is likely to be the case providedone had not previously considered these matters. And in particular,as the season and the year advances, he can tell what epidemic diseaseswill attack the city, either in summer or in winter, and what eachindividual will be in danger of experiencing the change of regimen.For knowing the changes of the seasons, the risings and settings ofthe stars, how each of them takes place, he will be able to know beforehandwhat sort of a year is going to ensue. Having made these investigations,and knowing beforehand the seasons, such a one must be acquaintedwith each particular, and must succeed in the preservation of health,and be by no means unsuccessful in the practice of his art.
