Answer:
Enzymes speed up a chemical reaction making the reaction easier to occur.
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:
The correct answer is - B. Lichens.
Explanation:
Lichens are one of the pioneer species that can grow on bare rock such as moraine and help make soil for further ecological succession and making ground for other species.
Breaking the bare rocks to convert into the soil is part of the primary succession. Lichens are colonized over these rocks and they contain acid which leads to the breakdown of the moraine and other rocks.
