Answer:
There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
Elizabeth was a "granola mom"it was only natural and organic foods and therapies for her
family. She belonged to a food co-op and ordered special foods and home remedies through
the group
Elizabeth was well read and conscientious, and she had a remedy for everything
Little white pills that dissolved under the tongue treated everything from teething to bruising.
When her 8-year-old daughter Samantha had a sore throat, Elizabeth had her gargle with
colloidal silver remedy used before all the new and "dangerous" antibiotics. Samantha did
get over her sore throat, but three weeks later, she broke out in a rash, complained that her
points hurt, and had swollen glands. This worried Elizabeth, and so she consulted a
conventional medical doctor.
Samantha was diagnosed with rheumatic fever, and the doctor prescribed antibiotic treatment.
Elizabeth had read that antibiotics could damage the immune system, and was reluctant to
give them to her daughter
How can you as a nurse, encourage compliance with long-term antibiotie treatment without
abenating Elizabeth? To what extent does a parent have the night to refuse medical advice for
a child? When are alternative therapies helpful?
Answer and Explanation:
1. As nurses, we can inform you that the use of antibiotics according to medical advice is not dangerous, because the doctor is able to prescribe a correct dose, which must be taken at the correct time intervals, to fight the disease without damaging the immune system . In that case, if the girl takes the medicine exactly as the doctor prescribed, she will have no problems and her body will recover completely.
2. Parents only have the right to refuse medical advice, when such advice is clearly abusive, puts the child at proven risk, or presents experimental treatments without scientific evidence, as it may endanger the child.
3. Alternative therapies are beneficial when they are accompanied by traditional medical treatment, or when they seek to promote relaxation and stress reduction, without trying to fight infections and more serious health problems.
Individuals with premutation length repeats in FMR1 may have some of the phenotypes of Fragile X but not others, which is _____________; for example, some individuals may have cognitive deficiencies, while others might have late onset ataxia. In addition, some individuals will have no phenotypes of the condition at all, due to ____________.
Answer:
variable expressivity; incomplete penetrance
Explanation:
In genetics, variable expressivity refers to the fact that individuals having the same alleles/genes/genotype associated with a particular genetic condition may exhibit different clinical features of this condition. In general, variable expressivity is due to the combination of both genetic and environmental factors. An example of variable expressivity is the Marfan syndrome, where all individuals with this disorder have a dominant mutation in the FBN1 (fibrillin 1) gene and show different degrees of the same phenotype. Moreover, incomplete penetrance (also known as reduced penetrance) refers to the complete absence of a genetic trait or disease in individuals having alleles/genes/genotype associated with the condition. In consequence, individuals with incomplete penetrance do not develop features of the disease. An example of incomplete penetrance is given by those individuals with mutations in BRCA1/BRCA2 genes (associated with an increased risk of developing breast cancer) that do not develop cancer.

Answer:
Take two potted plants and provide equal conditions to both.
Explanation:
Two potted plants i.e. one is placed near the nuclear accident site while on the other hand, the other is placed far away from the nuclear accident. Provide equal conditions to both plants so that we can find out the hypothesis that the frequency of mutations decreases with the organisms distance from the source of radiation. The result shows that the potted plant that is located near to the nuclear accident site having high frequency of mutation as compared to other plant due to the radiation present at that location.

An adult giraffe (Giraffa camelopardalis) has a heart that lies approximately 2 m below the top of the head when its neck is fully extended. Calculate the minimum diastolic pressure that a giraffe must have (in mm Hg). Hint: what is the absolute minimum blood pressure a giraffe could have at the very top of its head
Answer:
159.01 mmHg
Explanation:
position of Heart = 2m below the top of the head given that the neck is fully extended
Determine the minimum diastolic pressure
Minimum diastolic Pressure = 1060 kg/m^3 * 10 m/s^2 * 2m
= 21200 kg/m^2
convert the value to Pa
21200 kg/m^2 = 21200 Pa
( 1 pa = 0.00750062 mmHg )
Therefore : minimum diastolic pressure = 21200 * 0.00750062 = 159.01 mmHg
The minimum diastolic pressure that a giraffe must have is 150 mmHg
Diastolic Blood pressureDiastolic Blood pressure is the pressure on the walls of your arteries between heartbeats, that is when the heart is resting.
The minimum diastolic diastolic blood pressure = absolute minimum blood pressure a giraffe could have at the very top of its head.Pressure formulaP = hpg
where;
P = pressure
h = height difference
p = density
g = acceleration due to gravity
Density of blood = 1000 kg/m^3
h =2.0 m
g = 10 m/s^2
Pressure = 1000 × 2.0 × 10
Pressure = 20000 Pascal or 20 kpa
Converting to mmHg1 kpa = 7.50 mmHg
20 kpa = 20 × 7.50
Pressure = 150 mmHg
Therefore, the minimum diastolic pressure that a giraffe must have is 150 mmHg

What is the principle of size exclusion chromatography?
Answer:
The underlying principle of SEC is that particles of different sizes elute (filter) through a stationary phase at different rates. This results in the separation of a solution of particles based on size.
hope it helped
Size exclusion chromatography (SEC) separates molecules based on their size by filtration through a gel.
What is size exclusion chromatography?
Size exclusion chromatography (SEC) splits molecules based on their size by filtration via a gel. The gel consists of spherical beads including pores of specific size distribution. Separation happens when molecules of various sizes exist included or excluded from the pores within the matrix.
Size exclusion chromatography exists named gel filtration chromatography because the gel effectively allows for the filtering of molecules from a sample based on molecular size. However, unlike other methods, the larger molecules elute first.
Size-exclusion chromatography (SEC), also understood as molecular sieve chromatography, exists a chromatographic procedure in which molecules in solution exist separated by their size, and in some cases molecular weight. It exists usually applied to large molecules or macro molecular complexes such as proteins and industrial polymers.

Methylene blue can be used to stain DNA because it: (2 pts) forms ionic bonds with DNA changes the pH and therefore the structure of DNA makes DNA electron dense is an effective chemical fixative for cells is none of the above
Answer: Methylene blue can be used to stain DNA of a cell because it (forms ionic bonds with DNA).
Explanation:
To examine the components of a cell usually under a microscope, a stain or dye is being used to provide a clear and defined view of the area under study.
The deoxyribonucleic acid (DNA) of a cell which contains the hereditary information of the cell is located in the nucleus.
Methylene blue is a type of stain used by biologists which helps them view microscopic life in brilliant color. It is a cationic stain (positively charged blue dye); and binds to negatively charged parts of the cells, such as nucleus (DNA) and RNA in the cytoplasm (with lower affinity).
When DNA of a cell comes in contact with methylene blue on a slide, their opposite charges attract, causing methylene blue's "rings" to slide in between the "rungs" of the DNA "ladder." As a result, a rich blue stain that identifies the location of the cell nucleus can be observed. This produces a photosensitive reaction which can then be viewed under the microscope.
Therefore is can be used to stain the DNA of cell because it forms ionic bonds with DNA.
