What is your opinion on this controversy? What basic beliefs do you hold that cause you to feel as you do?

To review:
The controversy created due to human stem cell research.
Introduction:
A stem cell is a type of cell, which has not yet differentiated or acquired a specialized function. It can acquire a certain specialization upon receiving certain signals under appropriate conditions. This property of stem cells can be utilized to create different types of cells in a laboratory from stem cells by keeping them in certain appropriate conditions.
Explanation of Solution
Stem cells can be utilized in various fields of research. It can be used to study certain cell types and diseases. Stem cell research also has various clinical applications such as the treatment of diseases (stem cell therapy), which cannot be treated by other traditional methods. Thus, a person related to science should have an opinion that stem cell research should be supported.
The basic belief that leads to support stem cell research is that it can be used to benefit those, who are suffering from certain diseases like Parkinson's disease, which cannot be cured using conventional medical methods. Stem cell research also allows researchers to study diseases by creating disease models.
Such research would help in the further understanding and treatment of these diseases. Thus, it holds a promise with regard to improving the quality of human life. The counter-argument to stem cell research arises due to the use of human embryonic tissue, which is usually obtained from aborted fetuses. Some people may object to this due to their religious beliefs.
Therefore, it can be concluded that the controversy arising from stem cell research mainly arises due to the different belief systems held by different people. It is considered unethical but it holds many positive points that could benefit the mankind.

Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below. Note that carriers are not indicated with half-colored shapes in this chart. Use the letter "N" to indicate the dominant neurofibromatosis allele, and the letter "n" for the normal allele.

Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons 9 glycerol A. Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2. Continue generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration. glycerol glycerol-3- phosphate…arrow_forward
