Answer:
This question lacks options, the complete question is: What do you think would have the greatest effect on the body—a harmful mutation in a pluripotent embryonic stem cell, or a harmful mutation in an adult multipotent stem cell?The correct answer is a harmful mutation in a pluripotent embryonic stem cell.
Explanation:
Pluripotent Stem Cells can self-renew and differentiate into any of the three germ layers, which are: the ectoderm, the endoderm and the mesoderm. These three germ layers subsequently differentiate to form all the tissues and organs within a human being. If during embryonic development, genetic mutations - alterations in genes - occur in the embryonic stem cell, they pass to daughter cells as a consequence of cell division, and an individual is generated whose cells differ at the genetic level. Multipotent stem cells are organospecific cells, that is, they can give rise to any type of cells but from a specific organ (a lung, a kidney or the brain). Their differentiation ends the moment they specialize and become a cell with a specific function within a specific tissue or organ. If there were a mutation in these cells, it would damage a specific designed tissue or organ.
Answer:
The ability of species of living beings to overproduce offspring
Explanation:
Darwin proposed that species have the ability to produce offspring at a rate that could cause a geometric increase in the population size. This is called biotic potential. The overproduction of offspring causes intraspecific competition for the limited available resources. Darwin reasoned that the overproduction of progeny leads to a struggle for existence between the individuals of a population. He observed that the struggle for existence does not allow the population size of species to grow geometrically.
Answer
1. The vascular and dermal tissues
2. Protein capsid
Explanation
Dermal tissue present in plants offer the first defense mechanism against physical damage which could be caused by insects and infections.The dermal tissue covers the outside parts of a plant except in woody shrubs and tree which are protected by the bark. Vascular tissues in plants are responsible for the transportation of water and nutrients that are vital in cell repair and growth.Through vascular tissues, the plant obtains nutrients important for the restoration of the damaged cells.
A capsid is the protein shell of a virus.It is composed of protomers which are subunits.Some viruses are enveloped by a capsid coated with a lipid membrane called the viral envelop.The main function of a capsid is to protect the genetic material of a virus while interacting with the host environment.
