Answer:
Human various activities like burning fossils and huge land cover changes contribute to increasing the carbon dioxide of atmosphere.
Explanation:
- Carbon dioxide level in atmosphere is increasing naturally by organism respiration, decay, volcanoes erupt and carbonated rocks are weathered.
- Human activities like, urbanization, deforestation, vegetation pattern changes results in changes to reflectivity of earth surface and emmision through burning fossils fuels/forest and cement production are causining an increase in atmospheric carbon di oxide level. When fossils fuel burn the carbon combine with oxygen to form CO2.
- All these processes ultimately contribute to global warming.

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).
