One of your friends is arguing that viruses are alive. What information would you provide to convince him that viruses can't be
Alex777 [14]

Answer:

The correct answer is option 4.

Explanation:

Viruses cannot be considered alive as they cannot carry out metabolic reactions on their own. Metabolism signifies the tendency to gather and use energy. The chemical reactions in the cells spontaneously change the molecules into the forms of energy, which can be utilized by the organism.  

However, in the case of viruses, they are too small and simple to collect and utilize their own energy. They are completely dependent upon the host cells for energy. The viruses only require energy when they need to make duplicates of themselves, however, they do not require any energy when they are present outside of the cell. Thus, as they cannot carry out metabolic reactions, they are not considered as living.

From which part of the embryvo are embryonic stem cell lines derived?
vaieri [72.5K]

Answer:

Undifferentiated inner cell mass

Explanation:

Human embryo has two types of cells in its initial stage, trophoblast and inner cell mass.  Trophoblast forms the placenta and inner cell mass form the entire human body. Inner cell mass are pluripotent in nature i.e. they can give rise to any body part under right conditions.

Embryonic stem cells are derived from the inner cell mass. They are derived from pre implantation embryo since after implantation the inner cell mass begins to differentiate. Embryonic stem cells can replicate indefinitely without differentiating. They can give rise to all the three germ layers: ectoderm, mesoderm and endoderm. They can treat a number of disorders like genetic disorders, Parkinson's, spinal cord injury, cancers etc.

(A physical examination of the cats siblings) because you cant check its kittens, because there could be a dominant phenotype that caused them to have short tails. A physical examination of the cat wouldn't help either.
