Answer:
Stem cells have the ability to divide <u>through mitosis</u> and produce unspecified cells. Stem cells can be developed into a required tissue because of their ability of <u>differentiation</u>.
Explanation:
A stem cell is a cell that is in an undifferentiated state. This means that it has not specialized in a specific type that carries out a specific function of that tissue, which does not imply that stem cells do not have their own function. The concept of stem cell is due to the ability to originate specialized cells from one or more tissues, depending on the degree of potency or plasticity it has. They are found in all multicellular living organisms. Their main characteristic is that by reproducing through the process of mitosis (they divide into two cells) they can form more stem cells or differentiate, that is, they become specialized cells, in such a way that they are essential for the renewal of cells in different tissues. and to repair them.

Answer:
<em>The correct option is D) Diane will have to travel a farther distance to move the chair.</em>
Explanation:
To slide the chair up an inclined path, Diana would have to travel a further distance. While using the ladder to reach the second floor window would have made the distance smaller, but more force would have been required to move the chair through climbing a ladder. Diane would have got easily exhausted for moving the chair across the ladder. Using the inclined path will make the distance farther but as much force would not be required in this process. Hence, the method of using an incline is better.
The abdominal cavity is lined by peritoneum. It is a membrane that covers the inner layer of the cavity and also the organs inside. The membrane on the inner wall is parietal Thperitonium and the membrane that lines the organ is called visceral peritoneum. This helps in fixation and support of abdominal organs.
