write a paragraph of at least three sentences about stem cells. the paragraph should include what stem cells are, the controversy around them, and your opinion about using them for research.

answer:

stem cells have the extraordinary power to develop into several body cell types during early growth and development. (stem cell basics). stem cells are either embryonic: from a human fetus, or somatic: from an adult (stem cell basics).these cells can be used to rebuild body tissue, treat diseases, and even cure others. they can be more effective in treatment of illness than the common treatment, such as therapy or medication. stem cells are potentially more medically effective than traditional treatments.

stem cells can be used to treat a number of patients. vincent segers and richard lee stated in their article over cardiac cell research “these new findings have stimulated optimism that the progression of heart failure can be prevented or even reversed with cell-based therapy.” (segers). the two are referring to the ability of stem cells to develop into several types of cells present in the heart when they refer to “optimism”.   in j. mary murphy’s article over stem cell research and osteoarthritis, stem cell therapy in a caprine model of osteoarthritis, murphy states that “in cell-treated joints, there was evidence of marked regeneration of the medial meniscus, and implanted cells were detected in the newly formed tissue

answer:

explanation:

stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. in addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. when a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

stem cells are distinguished from other cell types by two important characteristics. first, they are specialized cells capable of renewing themselves through cell division, sometimes after long periods of inactivity. second, under certain physiologic or experimental conditions, they can be induced to become tissue- or organ-specific cells with special functions. in some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. in other organs, however, such as the pancreas and the heart, stem cells only divide under special conditions.

although it might seem great for researchers to study stem cells and research on them cloning human embryos is not cool and i frankly disapprove.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
