Let's begin by taking a step back and considering leukemia and lymphoma in general. We learned that an important way to classify
cancers is to consider the cell of origin. Leukemias and lymphomas are cancers that arise from a. hematopoietic (blood) cells, or the cells that give rise to mature blood cells
b. white blood cells, or the cells that give rise to mature white blood cells, only
c. lymphocytes, or the cells that give rise to mature lymphocytes, only.
d. mature lymphocytes only.
The correct answer is option a. "hematopoietic (blood) cells, or the cells that give rise to mature blood cells".
Explanation:
Leukemias and lymphomas are two forms of blood cancer. The difference between leukemias and lymphomas, is that leukemia affects the blood and bone marrow, and lymphoma affects only the lymph nodes. Wherever the location affected by these two diseases, Leukemias and lymphomas arise from the transformation of hematopoietic (blood) cells (or the cells that give rise to mature blood cells) into hematologic malignancies.
The kind of muscle contraction that occurs when you try to lift a box but it's to heavy and it can't be moved from the floor is called: Isometric Contraction.
Explanation:
Isometric contraction consists of having a muscle activated but to maintain it at a constant length, instead of shorten or lengthen it.
