According to your worldview, what value does a human person have? How does your position affect your stance on controversial bio
nalin [4]

A human life is so valuable that no single price should be placed on it. The effect on this stance on bioethical issues however, is relative.

<h3>Relativity of Human value to Bioethical issues</h3>
  • A person's stance on a bioethical issue can be based on which human life they value more, the person that will gain, or the one that will be affected.
  • With abortion, one might argue that the value of the mother is higher than the baby's because not having to take care of a child will give her a better life.
  • Designer babies might be more valuable because their lower rate of birth defects mean that they are tougher and less expensive to maintain.
  • Stem cell research could save many lives so more value might be placed on these lives than the embryos affected.

In conclusion, a person can see another life as valuable yet have relative views on bioethical issues.

Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size.

OLEGan [10]

Answer:

Water sample showing pink/purple color is an error.

Explanation:

Biuret is a blue color reagent that changes its color to pink/purple whenever it detects protein in a sample. Water don't contain proteins so it should not show pink/purple color instead it should maintain the blue color. Food items generally contain proteins so it show pink/purple color but it showed blue color.

Error might have caused by wrong marking of the samples, test tube marked with Water might contain a mystery food while Mystery food tube might contain water.
