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.

Si Se Sumerge En Un Vaso De Agua Una Piedra, Un Bolígrafo Y Un Tajalapiz. ¿Que Sucede?.

Arturiano [62]

Answer:

Al introducir una piedra en agua, está se va al fondo del vaso, por que es más pesada que el agua

Al introducir un bolígrafo, este flota, por que es más liviano que el agua

Si se introduce en agua un tajalapiz se evidenciará un proceso de corrosión del metal

Debido a la reacción con el agua, sin embargo el efecto será más evidente si se agrega sal a la mezcla

solong [7]

Answer:

Option - An open circulatory system inside the adults.

Explanation:

A terrestrial animal species is discovered with the following larval characteristics: exoskeleton, system of tubes for gas exchange, and modified segmentation. A knowledgeable zoologist should predict that the adults of this species would also feature an open circulatory system.
Most of the invertebrates like the insecticides have the open circulatory system, as the system has no specific pathways for the transportation of the materials and other essential nutrients through the medium but they have a more different mechanism in order to provide the sufficient materials to survive.

In pea plants, the allele for tall stalks (T) is dominant over the allele for short stalks (t). Suppose a cross between a tall p

vazorg [7]

Answer:

Tt - 1/2

tt - 1/2

Explanation:

A cross between a tall pea plant and a short pea plant that produces 43 tall and 47 short offpsring (almost 1:1) is most likely a cross involving a heterozygous tall individual and a homozygous short individual.

Tt x tt

Offspring = Tt Tt tt tt (50% tall and 50% short)

If one of the tall offspring (Tt) is crossed with one of the short offspring (tt):

Tt x tt

Offspring = Tt Tt tt tt

Genotype ratio = 2Tt:2tt

Hence,

Tt = 1/2

tt = 1/2

In the first part of the dna isolation, you discarded the supernatant and kept the cells. however, after processing the sample w

pishuonlain [190]

For the first step, you must isolate the cells from the media. The cells contain the DNA so you keep the cells and pellet. The next step would be a cell lysis which causes the cells to open and the DNA to come out. At this point you would keep the supernatant, as the pellet is the cell membrane and other parts of the cell. The chelex is to bind to transition metal ions. This would cause and DNases in the cell to become inactive because the metal ion is their cofactor. The pellet in this case would contain the chelex and the DNA would still be in the supernatant.
