What type of problems do high school STEM programs teach students to solve?

Lemur [1.5K]

Answer:

Stem cell therapy is a non-invasive treatment that aims to replace damaged cells within the body. Mesenchymal stem cell therapy can be deployed systemically via IV or injected locally to target specific sites, depending on patient needs.

Explanation:

Stem cell therapy is a form of regenerative medicine designed to repair damaged cells within the body by reducing inflammation and modulating the immune system. This phenomenon makes stem cell therapy a viable treatment option for a variety of medical conditions. Stem cell therapies have been used to treat autoimmune, inflammatory, neurological, orthopedic conditions and traumatic injuries with studies conducted on use for Crohn's disease, Multiple Sclerosis, Lupus, COPD, Parkinson's, ALS, Stroke recovery and more.

Bacteria and other microbes can be used to "clean up" an oil spill by breaking down oil into carbon dioxide and water. Two sampl

aksik [14]

Answer:

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

Explanation:

The composition of nitrogenous bases in DNA is calculated using the suggestions proposed by the results of the experiment performed by Erwin Chargaff.

He found that in a DNA sample the composition of purine to pyrimidine is 1:1. This indicates that the amount of purine equals pyrimidine. This can be presented as purines + pyrimidines= 100. Also, adenine binds thymine and cytosine binds guanine.

In the given question,

For sample A

A= 17.7 %, Therefore, thymine will be = 17.7 %,

A+T= 35.40%

Now, G+C=100- 35.40%

G+C= 64.60%

content of G= 64.60/2= 32.30%

content of C= 32.30%

For sample B

T=28.9%, A will be= 28.9%

A+T= 57.80%

G+C=100-57.80%

G+C= 42.20%

Thus content of G will be= 42.20/2=21.10

content of C= 21.10%

Thus,

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

You have identified two mutants with same phenotype.

algol13

Answer:

No, there are multiple ways in which different mutations in the same gene can cause the same phenotype

Explanation:

Several different mechanisms of mutation can lead to the same phenotype. For example, lets say our phenotype is that flies have white eyes, and we know that this occurs in one particular gene that normally makes the eye colour red. (the red gene)

These mutations likely rendered the red gene ineffective (as the eyes are not red). However, this could happen in a variety of ways.

There could be a single base deletion in the first exon of the mRNA, changing the reading frame of the protein and messing up the entire sequence (a frame shift mutations)
The entire gene could be deleted
A single base could be substituted in an important site of the gene, for example, one which translates into a catalytic residue or binding site in the protein
There could be an inversion at the promoter region of the gene, such that a transcription factor can no longer bind to transcribe the gene.

There are countless other ways in which a mutation could have been caused. Therefore, just because we know the same gene is affected does not mean that we can assume the mutations are identical.

Testing Two-Point Discrimination

yanalaym [24]

Two-point discrimination is the minimal distance which someone can perceive two different stimuli that given simultaneously. An area with higher receptor density will have a lower two-point discrimination result since the distance between receptor is lower.
The area that needs a high sensitivity like the palm of the hands(especially the fingertips), face, and tongue should be the one with lowest two-point discrimination.

In this report, anterior forearm two-point discrimination result is the lower than the fingertip. This result is suspicious since the forearm shouldn't more sensitive than the fingertip. Fingertip two-point discrimination is around 2-6mm and forearm should be much higher than 6mm.

Which of the following accurately describes kidney function? A. Kidneys are directed by the presence of antidiuretic hormone to

defon

Answer - B. Kidney function is controlled by the blood's composition and hormones.

Reasoning - Well to start off the kidneys (main) purpose function is to clean your blood which is very Important with blood composition. Second It can also and will excrete it through urine which is pretty much what it does. Oh and also a little bit of hormones.
