A classmate has asked you to help them determine the concentration of DNA in their solution. Their A260 reading was 1.69. What was the concentration of their DNA
Answer:
Acid , phenol or protein
Explanation:
The ratio of absorbance at 260 and 280nm is what is usually used to assess the purity which a DNA or RNA posses. A ratio of 1.8 is generally accepted as being pure for a DNA sample and a ratio of 2.0 is generally accepted also as being pure for RNA. when the ratio is significantly lower in each case, it indicates that there is presence of protein, phenol or other contaminants.

Which products do not have scientific studies supporting their claims to be beneficial when used?
A. Cofactors and coenzymes to support enzyme function
B. Lactase enzymes used in milk sugar digestion
C. Enzyme that aids in the digestion of oligosaccharides
D. Enzymes to promote immune system function
Cofactors do not bind to the enzyme, whereas coenzymes frequently bind loosely to an enzyme's active site and help recruit substrates. Coenzymes are organic compounds. Thus, option A is correct.
What is the importance of Cofactors and coenzymes?Cofactors and coenzymes are substances that support the proper operation of an enzyme or protein.
Cofactors are organic and inorganic substances that help enzymes catalyze processes. The majority of coenzymes are vitamin derivatives that are soluble in water by phosphorylation.
Typically, cofactors are used to provide chemical groups or qualities that are absent from other chemical groups.
A cofactor like ATP, for instance, has a special capacity for transferring energy to power chemical reactions like the activity of enzymes and transport proteins.
Therefore, Cofactors and coenzymes to support enzyme function.

A student wants to know what effect temperature will have on the germination rate of radish seeds. To test this, she obtains 3 petri dishes and 60 radish seeds. She places 20 seeds in the first petri dish and stores it at room temperature. She places another 20 seeds in the second dish and places it in the freezer. She places 20 seeds in the third petri dish and places the dish in an incubator. Over the next two weeks, she waters the dishes daily and records the number of seeds germinate. At the end of the experiment she calculates the germination rate for the seeds at each temperature.
Hypothesis: ____________________________
Experimental Group: ____________________________
Control Group: ____________________________
Manipulated Variable (IV): ____________________________
Responding Variable (DV): ____________________________
Constants: ____________________________
Answer:
Hypothesis: IF the temperature is high, THEN the germination rate of radish seeds will increase.
Experimental Group: 20 Seeds in petri-dishes placed in the freezer and incubator each
Control Group: 20 seeds stored at room temperature
Manipulated Variable (IV): TEMPERATURE
Responding Variable (DV): GERMINATION RATE
Constants: Amount of water, same amount of time (2 weeks)
Explanation:
- The hypothesis is a testable explanation given to an observed problem. A possible hypothesis is IF the temperature is high, THEN the germination rate of radish seeds will increase.
- Independent or manipulated variable is the variable that is changed or manipulated variable in an experiment. The TEMPERATURE is the independent variable in this case.
- Dependent or responding variable is the variable that is measured in an experiment. In this case, the dependent variable is the GERMINATION RATE
- The experimental group is the group that receives the experimental treatment. In this case, the experimental group is the 20 Seeds in petri-dishes placed in the freezer and incubator each.
- The control group is the group that does not receive the experimental group. In this case, the control group is the 20 seeds stored or placed at room temperature.
- Constants are the variables that are kept unchanged throughout the experiment. In this case, the constants are Amount of water, same amount of time (2 weeks)

Ozone definitely protects us from various harmful radiations and prevent the direct entry of UV rays falling on Earth. There is a case in which if ozone is present at the ground level it is considered as a pollutant. the correct answer is option C.
What is the hole associated with the ozone layer ?It is the black hole that is continuously rising and getting bigger in size though the more study about it is still unsolved.
Ozone high in Earth's atmosphere protects from the sun's dangerous radiation. But on the ground level, ozone is definitely an air pollutant that spoils people and plants. Ground-level ozone formed when nitrogen oxides along with the volatile organic compounds reacts to each other in sunlight and more hot temperatures.
Ozone at ground scale is a harmful air pollutant because of the effects on people and the related environment and it is main ingredient in “smog."

I NEED HELP ASAP Sensors on a spider's legs feel the vibrations of a trapped insect and relay the information to the spider's brain through nerve electrical signals. For nerve cells to maintain these electrical potentials, sodium must be removed from the cell and potassium must be moved into the cell. Describe why this process is a form of active transport and what is required for active transport to occur?
Answer:
Please find the explanation below
- Energy (ATP) is needed for active transport to occur
Explanation:
According to this question, sensor's on a spider's legs relay information via nerve electrical signals to the brain when the vibrations of a trapped insect is felt. However, for nerve cells to maintain this electric potential, ACTIVE TRANSPORT must be carried out by removing sodium from the cell and potassium must be moved into the cell.
This is a form of ACTIVE TRANSPORT because pottasium ions are moved into the cell against concentration gradient i.e. from a region where it is in low concentration to where it is in high concentration. This active transport process is usually accompanied by the use of energy in form of ATP.

After Pedro had breakfast, he went for a run. Identify at least three energy transformations that had to take place to allow Pedro to complete his run. Then use evidence to support the claim that energy in this system was conserved as it was transformed.
1) Chemical to mechanical (calories -> muscle contractions)
2) mechanical to mechanical (muscle -> motion)
3) mechanical to thermal (motion -> heat from the body causes sweating)
The potential energy is stored in the body chemically (via food). That potential energy is then released when the body is put in motion.
Suppose that you began a one-year study of tuberculosis (TB) in St. Petersburg on January 1st, 2018. You enrolled 200 residents in your study and checked on their TB status on a monthly basis. At the start of your study on January 1st, you screened all 200 residents. Upon screening, you found that 10 of the healthy residents were immigrants who were vaccinated for TB and so were not at risk. Another 10 residents already had existing cases of TB on January 1st. On February 1st, two residents developed TB. On April 1st, three more residents developed TB. On July 1st, three of the residents who had existing TB on January 1st died from their disease. The study ended on December 31, 2018. Assume that once a person gets TB, they have it for the duration of the study, and assume that all remaining residents stayed healthy and were not lost to follow-up.
What was the prevalence of TB in the screened community on January 1st?
Answer: 5%
Explanation:
The Prevalence rate is the term used to describe the percentage of a population that have contacted the disease being tested for. It is usually done over a certain period or a certain time.
The prevalence of TB in the screened community on January 1st therefore is;
= Number of infected/ No. of Tested residents
= 10/200
= 5%
