Diferentiate between embryonic stem cells and adult stem cells. In what way are the ethical dilemmas associated with the use of

embryonic stem cells different than those posed by the use of adult stem cells?

Answer:

Explanation:

<h2><u>Embryonic stem cells</u></h2>

These stem cells come from eggs that have been fertilized in vitro during IVF procedure, and were donated for research with the consent of the donors.

They are pluripotent: they have the potential to differentiate into almost any cell in the body.

<h2><u>Adult stem cells</u></h2>

Found in most organs in an individual who has already been born, they are responsible for tissue renewal or repair of damage. They can renew themselves or differentiate into the cell types of the tissue of origin.

They are multipotent, thus limited in their ability to differentiate: they will only produce specific cell types (e.g. neural stem cells produce neurons and glia).

<h2><u>Ethical concerns</u></h2>

The research with embryonic stem cells starts with an embryo in its early stages that can't develop outside the womb. Some people consider this early embryo a human being and are against scientific research with it, while others think that it's not a human being yet and research is not harmful because it couldn't survive unless implanted. In addition, experimentation with embryos could induce unplanned genetic mutations that could cause clinical aberrations if the embryo were implanted and allowed to develop into an adult individual.

In contrast, adult stem cells are not really controversial as they are cells derived from tissues from grown individuals. The main ethical issues are related to donor consent to obtain the cells.

This image shows the various forces acting on a block of rock situated on a rock slope. What does arrow 4 represent?
AlladinOne [14]

Answer:

4 is gravitational force

Option B

Explanation:

This is a force diagram of a block on an inclined plane.

The force component is what makes up weight in the diagram. Weight is given as mass multiplied by the gravity.

Gravitational force acts downward and it is the force of attraction between all objects and the earth. It is directly proportional to mass.

Force 1 and 2 are both shear forces that acts parallel to the face of the incline. They are mostly expressed as frictional forces.

olga55 [171]

Answer:

Cellulose is held by beta 1,4-glycosidic bonds making it linear while Glycogen is held by an alpha 1,4-glycosidic bond making it highly branched.

Explanation:

Cellulose and Glycogen are both carbohydrate polysaccharides formed from glucose monomers. According to the question, cellulose is a tough, fibrous, and insoluble (in water) polymer found to play a structural role in plants' cell wall while Glycogen is another polymer obtained from muscle or liver and disperses readily in hot water to make a turbid solution.

Although these two polysaccharides (cellulose and glycogen) are linked by (1, 4)-glycosidic bonds but the glucose monomers in CELLULOSE are linked by a beta 1,4-glycosidic, hence, making it a straight or linear polymer

GLYCOGEN, on the other hand, is linked by an alpha 1,4-glycosidic bond making it an highly branched polymer. This structure is responsible for the different physical properties of the two molecules.

Alecsey [184]

C is incorrect

Both acids and bases produce ions in solution, are electrolytes, and conduct electricity in solution. Although red litmus is an indicator, it does not change color in an acid, acids are proton donors while bases are proton acceptors. Soaps often contain bases, not acids.

D) conduct electricity in water. is the correct answer
