Constructing Plant Phylogeny Based on Morphological Characteristics and Molecular Data Phylogeny is the study of evolutionary relationships among groups of living and extinct organisms on earth (Campbell et al.‚ 2011). To show evolutionary relationships‚ a phylogenetic tree (a visual representation of the lineages among organisms) is constructed. All phylogenetic trees are hypotheses that are to be tested‚ modified‚ and tested again. One type of tree‚ known as a

Stem cells are a growing field for research. Many pursue this field due to the fact that it can solve many illnesses. Since stem cells are extracted from embryos‚ people have an ethical problem with it. Those who research stem cells believe there are ethical restrictions‚ but that is not true. As a result of stem cell research‚ embryos are being harmed or destroyed; therefore stem cell research should only be performed if there is an alternative solution. Stem cells are undefined cells that are

technologies to help cure a vast array of debilitating medical conditions. Thanks to stem cell research scientist are able to test new medications‚ learn how to repair or generate tissues or organs‚ understand disease processes and create many promising therapies. There is endless potential for scientists to learn about human growth and cell development from studying stem cells. However‚ there is a big controversy whether or not stem cell research is ethical‚ which continues to be an obstacle in advancing research

Ethical Dilemma on Stem Research Discussion of the bioethics of human stem cell research has transitioned from controversies over the source of human embryonic stem cells to concerns about the ethical use of stem cells in basic and clinical research. Key areas in this evolving ethical discourse include the derivation and use of other human embryonic stem cell–like stem cells that have the capacity to differentiate into all types of human tissue and the use of all types of stem cells in clinical research

The most exciting use of the stem cells depend on their their the ability to differentiate into a wide range of functioning adults cells. This gives a replacement source of the cell to treat any serious disease. That means that technically any disease that cellular and tissue destruction it can be treated with the stem cell. Some diseases consist of heart disease

Stem cell research is the study of cells which are known as unspecialised cells these cells are also known and referred to as stem cells. A stem cell has the ability to differentiate into any cell during early growth and development of an organism. Stem cells all have very unique qualities; these qualities help them to serve the body’s needs. They are able to survive for long periods of time as they can regenerate themselves and also self-replicate‚ they are also unspecialised cells and have the

Many different debates have been raised to justify and unjustified the use of stem cells for research throughout the years. The two most enduring debates that have stood the test of time have been the legal and ethical issues. The has been documented in countless research

2/15/13 Period 2 Research on the use of embryonic stem cells has sparked controversial debates all over the United States. What makes them so controversial? It is where they come from. Embryonic stem cells are “blank cells” harvested from an early stage embryo that have the potential to turn into any kind of cell in the human body. Usually‚ these embryos are unused from in vitro fertilizations and would otherwise be thrown away. Embryonic stem cells have the potential to treat people with diseases

What pH Level Causes a Plant to Grow Best Alexis Chavez‚ Heather Nutt‚ Nguyen Phan Introduction We knew that water is normally stated as the best form of liquid to make sure plants grow as best as they can‚ but we wanted to know if causing the water to be more basic or more acidic would affect how the plant grew. Our hypothesis was that if the plant is treated with a pH of 12 then treated with another pH. Materials The materials used were three identical plants‚ that each had 4 sections that were

Bringing a baby into this world is one of God’s greatest creations. Babies should be born out of love from their mother and father. That is why so many people are against embryonic stem cell research‚ designer babies‚ and pre-implantation genetic diagnosis. These procedures go along with the concept of the novel and of how Anna was conceived by in vitro fertilization. They go against the catholic religion due to the fact that creating a baby in a petri dish defeats the whole purpose of natural conception
