Why is adult stem cell research less controversial than embryonic stem cell research?
question 20 options:

adult stem cell research has wider medical applications.

consent can be obtained from adult stem cell donors.

donated cadavers can be used to harvest adult stem cells.

stem cells from adults require no animal experimentation.

The correct option would be B. consent can be obtained from adult stem cell donors.

The controversy behind the other option is that it is a form of life, but no consent is taken from the actual life. (i know it's phrased weirdly, my bad)

Consent can be obtained from adult stem cell donors.

Explanation:

Considered very special cells, stem cells appear in humans even during the embryonic phase, that is, even before birth. As soon as the baby comes into the world, some organs still hold a small portion of stem cells within them, which become responsible for the constant renewal of that specific organ. The extraction of these stem cells has been the subject of controversy for years. This is because many people believe that it is an invasion of the baby's body that does not have the capacity to consent and protect its own organism.

However, some of these stem cells accompany the human being until adulthood (in smaller quantities than the baby) the extraction of these cells in adults is less controversial, because unlike the baby the adult can consent to the manipulation of his organism.

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.
