Answer:
These seven methods include: seed propagation, cutting, layering, division, grafting, budding, and tissue culture technique.
Explanation:
The major methods of asexual propagation are cuttings, layering, division, budding and grafting. Cuttings involve rooting a severed piece of the parent plant; layering involves rooting a part of the parent and then severing it; and budding and grafting is joining two plant parts from different varieties.
The correct answer is A.
Muscles need energy to produce contractions. The energy is derived from ATP (which stands for adenosine triphosphate) that is present in muscle cells.
Muscles tend to contain only limited quantities of ATP. When depleted, ATP needs to be resynthesized from other sources namely creatine phosphate (CP) and muscle glycogen. Other supplies of glycogen are stored in the liver. The body is also able to resynthesize ATP from lipids, i.e. free fatty acids. Different sources of energy are used depending on intensity and duration of the workload .
Discrimination represent BEHAVIOR attitudinal component of prejudice.
Discrimination is always shown by the type of behaviors that are exhibited towards a certain group of people. For instance, after slavery had been abolished in America, some white employers still discriminated against black people by refusing to give them the same privileges that they give to white workers.
Researchers prefer to use embryonic stem cells instead of adult stem cells because embryonic stem cell can differentiate into more type of cells.Human embryonic stem (ES) cells capture the imagination because they are immortal and have an almost unlimited developmental potential. Embryonic stem cells are pluripotent cells not unipotent. After many months of growth in culture dishes, these remarkable cells maintain the ability to form cells ranging from muscle to nerve to blood—potentially any cell type that makes up the body.
