Genetic Problems A researcher studying petunia plants. These plants have either red or white and this characteristic is influenc

ed by one gene. The alleles are R red (red is dominant) and r white. She crosses to heterozygous red plant with a homozygous white plant. Determine the expected genotypes and phenotypes of the offspring using the steps outlined above.

Well, you would use Punnet squares. Don't forget that heterozygous means that the alleles are different so Rr. Homozygous means that the genotype will have the same genes rr. When you put together the Punnet squares, I always like to determine the percentage of phenotypes possible. In this case 50% of them are going to be white, and 50% of them are going to be red.

What is the purpose of woolite when extracting DNA?
Nitella [24]
Purpose:Extraction and successful PCR amplification of DNA from humanremains in historical and forensic cases have great importance. The purpose of this study is to demonstrate the efficiency of a method of DNA extraction and PCR amplification of embalmed dried human cadaveric skeletal fragments and teeth specimens from Sokoto, Northwestern Nigeria.
Materials and Methods: The efficiency of a method of DNA extraction and PCR amplification was tested on thirteen (13) embalmed dried human cadaveric skeletal fragments and nine (9) teeth specimens from Sokoto, Northwestern Nigeria were used in the study.
Results: Of the 13 embalmed dried human cadaveric skeletal fragments, 12 (92.3%) samples amplified with apparent bands. For the 9 embalmed dried human teeth specimens, 7 (78%) samples amplified with apparent bands.
<span>Conclusion: The study has shown that our method of DNA extraction and PCR amplification was efficient on embalmed dried human cadaveric skeletal fragments and teeth specimens, from Sokoto, Northwestern Nigeria.</span>

Y_Kistochka [10]

Answer:

False.

Explanation:

ANOVA is the analysis of variance may be defined as the collection of the statistical models and their procedures estimation. ANOVA can be used to determine the differences in the group mean samples.

The ANOVA was discovered by  Ronald Fisher. The two or more than two treatments in ANOVA does not mean that all treatments means are significantly different from the each other.  

Thus, the answer is false.

explain : in order to get rid of any effects of agricultural insecticides in the fruits, it is advised to soak them in a diluted
Vedmedyk [2.9K]

As we have studied in junior classes <em>that all animals including bacteria contain a plasma membrane around their cell which controls the movement of water and materials to and from the cell.</em>

The bacteria are the main hazard in pesticides and if we study about its structure, it contains both cell membrane and cell wall. Now another point in that bacteria lives in a moist or hypotonic environment in which the concentration of water inside the cell is less than the concentration of water outside the cell. This results in more movement of water from outside to inside the cell since we know that water moves from a place of higher concentration to a place of lower concentration.

Now when the water moves inside the bacterial cell, it can burst bacterial cell but thanks to the presence of cell wall which donot lets the burst caused.

So coming towards sugar solution, when bacteria are dipped in dilute sugary , the outside environment around a cell is sugary, and the concentration of water in the solution is less than inside the cell and water tends to leave the cell. the major effect of sugary solution is that it withdraws water from inside the body of micro organisms if the external concentration of sugar is high enough. When the water will move out of their body, they will die and their spores will not be able to germinate too.

This will eventually make our food (vegetable, fruit or any other) clean.

Hope it helps!
