Benedicts reagent is an indicator for the presence of ______________ in solution

1 answer:

8 0

In lab, we used Benedict's reagent to test for one particular reducing sugar: glucose. Benedict's reagent starts out aqua-blue. As it is heated in the presence of reducing sugars, it turns yellow to orange. The "hotter" the final color of the reagent, the higher the concentration of reducing sugar.

Answer:

The sample size is too small

Explanation:

<em>The problem most likely identified by Roberto would that the sample size is too small.</em>

A small sample size during an experimental study would decrease the statistical power of the data from such an experiment and increase the likelihood of making an error - type II error. Type II error occurs when the null hypothesis is confirmed instead of being rejected and this often occurs due to small sample sizes.

<u>The student used just a tomato plant for each study group. This represents a small sample size. Hence, the main reason for criticizing the experiment performed would be due to the small sample size.</u>

Explanation:

1. Yes, the MNI ought to be changed in light of the revised inventory. Since 4 of the 6 femora are right sided, they would belong to different individuals, so the MNI would now be stated as 4.

2. The sheriff would be told that the possibility of suspecting 22 individuals is very narrow, though not impossible. It is also unlikely that the victims are numbered less than 4 in accordance to the bones found.

damaskus [11]

The use of mRNA and reverse transcriptase in this case is part of a strategy to solve the problem of post-transcriptional processing. So the correct option is A.

<h3>What is post-transcriptional processing? </h3><h3> </h3>

The process of transcription results in the formation of a heterologous nuclear RNA (hnRNA) or a precursor RNA (PreRNA). This undergoes post-transcriptional processing to form mRNA. Following are the steps -

Splicing - it removes the non-coding introns so that only coding regions called exons remain.
Capping - a 5'-methylguanosine triphosphate is attached at the 5' end of the RNA.
Tailing - About 200 polyadenylate residues attach at the 3' end of the RNA.

These processes result in the formation of mRNA.

Therefore the correct option is A.
