When a person’s hair, nails, and skin areas are infected with fungus, such infections are determined by a doctor through the KOH test. While taking a skin sample for the test, the nurse or a doctor must use a scraping tool to remove the infected skin and place it in the KOH solution, which is later examined under the microscope.
Further Explanation:
The KOH or potassium hydroxide test is generally performed to check whether the cause of infection in the skin is a fungus or not. The constituent elements in KOH are potassium (K), hydrogen (H), and oxygen (O), which together produce potassium hydroxide. The products such as soft soaps, fertilizers, and alkaline batteries make use of KOH.
A change on the surface of the skin or skin lesion can be a result of infection through many agents. The KOH test is done when a fungal infection is suspected. The infection through tinea cruris and ringworm are the fungal infections usually determined by the KOH test.
The symptoms of the infection by a fungus include:
Red, itchy patches on the skin When it occurs in the mouth, white patches are seen Thickened or deformed nailsThe procedure of the test involves the following steps:
A small area of the skin is scraped through a glass slide or any other instrument. The scraped skin is kept in a potassium hydroxide solution. The KOH kills the healthy cell while keeping the fungal cells alive. A normal KOH test would result in the absence of fungal cells. An abnormal test result will have the presence of fungal cells. The presence or absence of the fungal infection is determined after examining the solution containing the infected skin area under the microscope.
Therefore, if the KOH solution degrades all the cells, the infection is not done by a fungus. This means that the symptoms might have occurred due to some other infectious agent. In the presence of fungal infection, the doctor might suggest further treatment.

In what way do nuclear reactors negatively affect ecosystems?
Answer:
The nuclear reactors are cooled down by using huge amount of water, this water when released in the atmosphere causes thermal pollution. the warm water when gets mixed in the lakes and rivers affects the aquatic life.The nuclear reactors does not releases carbon dioxide into the environment but the uranium that is used as a raw material has many negative consequences when it comes to mining.There can be misuse of the nuclear energy that can adversely affect the environment.Identify each family member's genotype in this pedigree for high-altitude adaptation. if you can't tell with certainty whether an individual is homozygous dominant or heterozygous dominant, place the label "rr or rr" in that box.
The primary enzyme for digesting cholesterol esters in the small intestine is called:
The enzyme is cholesterol esterase. This enzyme is found in the pancreatic juice and is usually secreted by the exocrine pancreas. Cholesterol esterase digests cholesterol esters in the lumen of the small intestine into free fatty acids and cholesterol. In the small intestine, bile salts such as cholate and its conjugate is required to stabilized this enzyme in its polymeric form and protect it from proteolytic hydrolysis.
What structures do sponges possess that may prevent other animals from eating them?
The answer is spicules. These sharp-pointed structures are formed from calcium carbonate skeleton of the organisms. They can also be formed from silica. They can be big (megascleres), or microscopic (microscleres). Also dependent on the number of axis on the spicules, they are classified as monoaxon, triaxon or polyaxon.

Explanation:
A cell has damaged DNA. Which checkpoint is responsible for checking this? M checkpoint
A cell has damaged DNA. The G2 checkpoint is responsible for checking this abnormality during the cell cycle.
How many checkpoints are there in a cell cycle?There are three major checkpoints that can be seen in the cell cycle. They are G1/S checkpoints, G2/M checkpoints, and the spindle assembly checkpoints (SAC).
The G2 checkpoint is responsible for checking the accurate replication of all chromosomes that have already been replicated. It also ensures that the replicated DNA is not damaged before the cell enters mitosis.
The G1 checkpoint prevents cells from replicating damaged forms of DNA and forces the cell to remain in the resting state.
Cell cycle checkpoints significantly regulate and control the overall mechanism of the cell cycle in eukaryotic organisms. They also ensure the accurate and valid progression of the cell cycle in each step of it.
Therefore, a cell has damaged DNA. The G2 checkpoint is responsible for checking this abnormality during the cell cycle.

Perforation plates are characteristic of the ________ of __________.
The major threat the GM foods pose to human health is:
You're looking for a "few good fats" that include essential fatty acids. the best place to find them would be in a ____________.
A friend argues that redundancy of the genetic code is due to wobble pairing. explain why this isn't the case.
Redundancy refers to the phenomenon where more than one codon in DNA code for the same amino acid. Wobble pairing means base pairing that does not follow the canonical G-C and (U)A-T rule. Wobble pairing allows for a tRNA to specify for more than one type of amino acid during the translation process.
Answer:
1. Wobble pairing is the phenomenon where the last nucleotide of the triplet codon is mainly rendered useless most of the time. But Redundancy is the phenomenon where one codon codes for more than one amino acid.
2. They are just opposite to each other, where in Wooble Hypothesis, more than one codon codes same amino acid, but in DNA redundancy, one codon codes for more than one amino acid.
3. Redundancy is seen In lower organisms, but Wooble hypotheses is seen in all organisms.

Explanation:
The hydraulic structure of dam has some sub structures which interferes with the natural navigation of the fishes within any water body.
Due to such interference the fishes get diverted to a different path of flow and hence are not accountable. This causes reduction in the number of fish counts.
The higher the construction of dams, the higher will be the effect of it on the fish navigation which will ultimately lead to reduction in fish count.
Hence, option D is correct.

The recessive allele that causes sickle cell anemia is harmful to homozygous individuals. what maintains the presence of this allele in a population's gene pool?
The one responsible for maintain the presence of this allele in the population’s gene pool is the heterozygote advantage. It is because the advantage of having this for a sickle cell disease is that if a person has a strong heterozygote advantage and that he or she has a copy of the allele that cause the sickle cell disease, the person will likely be resistant to the disease because of the heterozygote advantage in which the heterozygote genotype has a higher relative fitness making it resistant to the disease.
How do doctors and researchers decide whether a disease is a good candidate for gene therapy? what are the advantages and disadvantages of using viral vectors for gene therapy? what factors must be considered when choosing a vector for a gene therapy trial? a young boy suffers from neurofibromatosis type 1 (nf1), a genetic nervous system disorder that causes tumors to grow around nerve cells. the gene for nf1, approximately 8,400 base pairs long, is located on chromosome 11. what is the best candidate for a vector for gene therapy in this case? provide evidence from your research to support your choice. how does traditional gene therapy compare to the crispr-cas9 genome editing system? genome editing has many advantages for treating and preventing diseases, however there are many ethical concerns. explain one ethical concern related to genome editing. many athletes and administrators fear the widespread use of gene doping—the use of gene therapy to modify genes that improve athletic performance. describe at least two genetic modifications that would improve the performance of an athlete. make sure to mention the body system(s) affected as well as the specific goal of the therapy. explain how gene therapy can impact the future of humans as it relates to curing diseases and gene selection?
Diseases that are best candidates for gene therapy are those whose disorder has been identified to be a malfunctioning gene and the biology of the gene is well known. Gene therapy is also viable where the proper gene can be correctly delivered and replace the malfunctioned one.
The advantage of using viruses in gene theory is their effectiveness in delivering the desired gene by tapping into their natural mechanisms of infection. However, disadvantages include the risks of affecting healthy cells while targeting sick cells and wrong placement of the desired gene hence causing undesirable mutations in DNA.
One factor is the length of the DNA that is required to be replaced through gene therapy. Most vectors have a maximum length of DNA that they can carry for effective transduction. Another is the range of cell types that the vector can infect and the risk of immune response/ allergic reaction/ side effects.
The best vectors are herpes or vaccinia viruses. The viruses are able to infect non-dividing cells such as the nerve cell. The vectors can accommodate 8400 bp in their genome and the transgene expressions have the potential to last long.
Traditional gene editing techniques such as TALENS and ZFN use modular proteins that target nucleotide sequences. In the CRISPR tool, the Cas9 protein is steered by a guide RNA (which is a complementary sequence to the target sequence) to the target region.
One ethical issue of gene editing is its use in genetic enhancement to develop ‘designer babies’. The question of who should decide on whether a trait is bad or good also complicates this matter. The morality of artificiality enhancing attributes such as strength, athletic capability, intelligence, and etcetera could lead to an unhealthy ‘arms race’ between humans.
In sports doping, gene editing could be used to enhance genes that enhance muscle strength by targeting myostatin (MSTN) and GF-1 genes. Genes that promote quick break down of lactic acid and increases oxygen capacity of the lungs and blood such as EPO gene could be targets of sports doping.
Gene editing will treat diseases and disorders by repairing the causative defective gene. This is already applicable in cystic fibrosis. Artificial gene selection will be common in future thanks to gene editing. Future humans will, therefore, have ‘desirable traits’ or new traits depending on what is appealing to the society.
Marcus is admitted to the hospital for a bone marrow stem cell transplant from his brother.What will happen after his brother's stem cells are transplanted into Marcus?
Answer:
The stem cells will lodge in Marcus's bone marrow so that it can produce normal blood cells again.
Explanation:
The medulla is a gelatinous tissue that lies inside the bones, especially the iliac, located in the hip, and the sternum in the middle of the chest. Its function is to originate the three types of cells that make up the blood: red blood cells, leukocytes and platelets. In some situations, the marrow cells become defective and do not properly supply the blood cells, and a bone marrow stem cell transplant is not required to solve the problem.
During transplantation donated stem cells are infused through a catheter in the chest region. They travel through the circulation until they reach the inside of the bones, where they take care of the area, gradually forming a new healthy marrow. In other words, the stem cells will lodge in the bone marrow so that it can produce normal blood cells again.
Transplantation is a success as the marrow begins to generate a healthy dose of healthy cells. This is proven when neutrophils, a type of defense unit, exceed the 500 / mm3 rate on exams for two consecutive days.
