Researchers may be able to induce adult cells to behave like embryonic stem cells an important advance in stem cell therapy.
Embryonic stem cells :
Embryonic stem cells are found in the inner cell mass of the human blastocyst, an early stage of the developing embryo lasting from the 4th to 7th day after fertilization. In normal embryonic development, they disappear after the 7th day, and begin to form the three embryonic tissue layers.
How embryonic stem cells are obtained?
Stem cells are now being collected from human embryos. In most cases, the embryos that are used have been aborted or left over from in vitro fertilization procedures. Although not technically feasible at this time, researchers expect that it is possible to clone stem cells from a patient's own somatic cells.
Cell therapy :
Cellular therapy (CT) is the transplantation of human cells to replace or repair damaged tissue and/or cells. With new technologies, innovative products, and limitless imagination, many different types of cells may be used as part of a therapy or treatment for a variety of diseases and conditions.

Answer:
Mars
Explanation:
The Deep Freeze: Ice on Mars. Like Earth, Mars has ice caps at its poles. Water reaches the poles as vapor and is frozen into thin layers that build up thick deposits. Mixed with this water is dust picked up by the wind, so the caps have bright and dark layers of "clean" and "dirty" ice.
Answer:
FRONTAL LOBE
Explanation:
The frontal lobe can be located at the anterior part of the brain, extending back to a fissure known as the central sulcus. The frontal lobe functions and helps in coordination of reasoning, motor control, emotion, and language. It contains the motor cortex, which is involved in planning and coordinating movement; the prefrontal cortex, which is responsible for higher-level cognitive functioning; and Broca’s area, which is essential for language production.
Let say for example Kyle is my friend who was a victim of an accident.
Before the accident, he was industrious and well liked BUT after the accident, he is profane, impetuous, and incapable of working toward a goal.
Such changes in personality would be consistent with loss of impulse control which is a significant frontal lobe function. With connections between the planning functions of the frontal lobe and the emotional processes of the limbic system severed, Kyle had difficulty controlling his emotional impulses, attitudes and abiiity of working towards his goals.
Yes chromosomes, centromeres are the center of the cell chromatids are two identical parts and the chromosome are the coiled dna
