I just have a question, are you in seventh grade? I keep my binders from past years and I remember learning this, but don’t know if that’s the grade I learned it in, are you?
The pluripotent, undifferentiated cells in the bone marrow that give rise to the formed elements are called stem cells.
Pluripotent stem cells have the ability to undergo self-renewal and to give rise to all cells of the tissues of the body. However, this definition has been recently complicated by the existence of distinct cellular states that display these features.
There are two types of pluripotent stem cells :
- Embryonic stem cells (ESCs)
- Induced pluripotent stem cells
Embryonic stem cells are derived from the inner cell mass (ICM) of pre-implantation embryos and can be indefinitely maintained and expanded in the pluripotent state in vitro. Pluripotent stem cells can also be obtained by inducing dedifferentiation of adult somatic cells through a recently developed in vitro technology, known as cell reprogramming.
Similarly to Embryonic stem cells , Induced pluripotent stem cells can be expanded indefinitely and they are capable to differentiate in all the derivatives of the three germ layers.
Another intriguing features of being pluripotent is its reliance on gene expression heterogeneity.

The correct answer for this question is: "<span>B) kidneys clean the blood by filtering it to remove wastes." Kidneys clean the blood by filtering it and removing the waste.
The correct answer for this question is: "</span><span>A) secretes excess water as sweat." The role of the skin in the excretory system is to secrete waste and excess water as sweat.</span>
The answer is the option A. removing plants from hillsides eliminates the root structures that anchor soil. Indeed the roots of trees, further to anchor the tress to the floor, serve as a net to which the soil attaches preventing the soil of been washed and removed by rainstorms
