Answer:
ability to differentiate into other cell types during cell division i.e. totipotent nature
Explanation:
Stem cells are undifferentiated cells with the unique ability to develop into specialized cell types in the body during early life and growth through the process of cellular differentiation. When a stem cell divides, each new cell has the potential to either to remain a stem cell or become another type of cell with a more specialized function e.g muscle cell, red blood cell or a brain cell.
Stem cells provide new cells for the body as it grows, and replace specialized cells that are damaged or lost. This ability of stem cells to differentiate into a variety of cell types in an organism including embryonic tissue, is an important distinguishing factor. They have two unique properties that enable them do so:
1. They can divide over and over to produce new cells
2. As they divide, they can change into the other types of cell (cellular differentiation).
Answer:
El efecto del material sobre el medio ambiente es el aspecto a considerar.
Explicación:
Se debe verificar la estructura química del material o de qué elementos se forma un material para conocer el efecto de estos materiales en la salud y el medio ambiente de las personas. Si los materiales no afectan el medio ambiente y la salud humana, el ser humano puede utilizarlos para satisfacer sus necesidades. Si el material se forma a partir de elementos tóxicos o elementos que no se descomponen por microbios, entonces este tipo de materiales son peligrosos tanto para la salud humana como para el medio ambiente porque estos materiales contaminan el medio ambiente y debido a esta contaminación la salud humana se ve gravemente afectada.
Answer:
Correct answer is A since it is the only one that is oppositely faced and the shape of the boxes is same.
Not enough info, but I'd go with:
B) hydrogen peroxide
