Answer:-
A) and C)
Explanation:-
B) isn’t correct because DNA is double stranded unlike RNA which is single stranded.
D) isn’t correct because they are nucleic acids
Answer:
negative externality
Explanation:
In simple words, negative externality refers to the loss that an unrelated third party experiences due to any economic transaction that occurs between the other two independent entities.
Under this concept the two parties do not deliberately effect the third party and generally that third party do not get any chance to tackle the loss before it actually happens. Diseases happening to general public due to pollution by factories is the prime example of negative externality.
To ensure safety, leftovers that have been properly wrapped and refrigerated should be eaten within<u> three days.</u>
Leftovers can be kept for three to four days in the refrigerator. We should be sure to eat them within that time. After that, the risk of food poisoning increases. Food poisoning is the result of eating contaminated, spoiled, or toxic food. hence, to avoid such condition food must be consumed within shortest duration possible.

Answer:
Measurement of peripheral blood cytokines and other immunomodulatory proteins is a useful and popular tool for assessing human immune responses to a wide range of assaults. A common challenge in this work is obtaining fresh, high-quality samples and limiting the time between blood collection and the separation of plasma or serum from cells. In this study we sought to determine the effect of sample age at the time of processing on the measured levels of 41 soluble immune mediators. Two cohorts were examined: healthy lab donors and trauma patients, who have significant immune perturbation. Whole-blood samples were aliquoted, and plasma was isolated, at days 0, 1, 2, and 3 after collection. Multiplexing techniques were used to measure protein concentrations, and general estimating equations were used to determine if there was a significant change over time. Over the 3-day period examined, only 15 of the 41 proteins showed no significant change in either cohort. Among the remaining proteins both increases and decreases were observed, with changes ranging from 2.4% per day to 325% per day. Proteins with significant changes in one cohort did not always show significant changes in the other group. These results support the need to separate plasma or serum from whole blood as quickly as possible and/or to standardize the length of time to processing within a given study of peripheral blood protein concentrations. When this is not possible, care should be taken to account for differences due to sample age.
Explanation:
A bacterial STDs are caused by bacteria that enters the body either through skin contact or body fluids. a viral std is a sexually transmitted infection that is caused by a virus. unlike bacteria viruses these are not living organisms and need a host cell in order to replicate and survive. some of the most common vital stds are HPV, herpes, hepatitis and HIV these cannot be cured however although a virus will remain in the body for life symptoms of the virus that might be not be present at all times.
