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.
Burning fossil fuels will produce carbon dioxide which is a global gas causing global warming . Global warming causes the sunlight to be trapped in the atmosphere of the earth which will cause the temperature of the earth to increase. so the polar ice will melt and the sea level will increase
Most of the time they become reproductive in the late winter and give birth in early spring. Thanks for posting your questions on brainly!
Answer:
Explanation:
A scientific researcher performs scientific methods to answer any natural process. The researcher will follow the protocol of a scientific method which includes: observe the natural phenomenon, ask related questions, suggest a hypothesis, perform the experiment and suggest answers.
In the given question if the researcher has to study about the flu virus, the possible questions he would ask will be:
1. The life cycle of the flu virus.
2. Effect of the virus on the life of an organism.
3. The mechanism used by the virus to replicate and to infect any organism.
4. Molecular mechanism of a virus.
Answer:
Brachydactyly and Huntington are phenotypic diseases that develop when a person has one or two dominant alleles for these traits.
John's father has the Huntington disease, but not brachydactyly so his genotype is Hh/bb.
John's mother is a healthy women with brachydactyly, so her's genotype is probably hh/BB or hh/Bb.
