Question: Answer the following question given this paragraph: ability to diversify at each step. The totipotent stem cell is the zygote, or fertilized egg. The totipotent (toti- = "all") stem cell gives rise to all cells of the human body. The next level is the pluripotent stem cell, which gives rise to multiple types of cells of the body and some of the supporting fetal membranes. Beneath this level, the mesenchymal cell is a stem cell that develops only into types of connective tissue, including fibrous connective tissue, bone, cartilage, and blood, but not epithelium, muscle, and nervous tissue. One step lower on the hierarchy of stem cells is the hemopoietic stem cell, or hemocytoblast. All of the formed elements of blood originate from this specific type of cell. Hemopoiesis begins when the hemopoietic stem cell is exposed to appropriate chemical stimuli collectively called hemopoietic growth factors, which prompt it to divide and differentiate. One daughter cell remains a hemopoietic stem cell, allowing hemopoiesis to continue. The other daughter cell becomes either of two types of more specialized stem cells (Figure 18.4): Lymphoid stem cells give rise to a class of leukocytes known as lymphocytes, which include the various T cells, B cells, and natural killer (NK) cells, all of which function in immunity. However, hemopoiesis of lymphocytes progresses somewhat differently from the process for the other formed elements. In brief, lymphoid stem cells quickly migrate from the bone marrow to lymphatic tissues, including the lymph nodes, spleen, and thymus, where their production and differentiation continues. B cells are so named since they mature in the bone marrow, while T cells mature in the thymus. Myeloid stem cells give rise to all the other formed elements, including the erythrocytes; megakaryocytes that produce platelets; and a myeloblast lineage that gives rise to monocytes and three forms of granular leukocytes: neutrophils, eosinophils, and basophils. Q: Which cell gives rise to all cells of the human body? A:
OPTIONS:
- signaler stem cell
- omnipoten stem cell
- schwann stem cell
- totipotent stem cell
Answer: totipotent stem cell

input with options: Answer the following question given this paragraph: Some substances are too big to be pumped across the cell membrane. They may enter or leave the cell by vesicle transport . This takes energy, so it's another form of active transport. You can see how vesicle transport occurs in Figure below . Q: A substance too big to be pumped across the cell membrane may enter or leave the cell by what method? A:
OPTIONS:
- absorption
- vesicle infusion
- passive transpiration
- vesicle transport
output: vesicle transport

Q: Answer the following question given this paragraph: Anabolic reactions involve forming bonds. Smaller molecules are combined to form larger ones. For example, simple sugars are combined to form complex carbohydrates. Anabolic reactions require energy, so they are endothermic. Q: Anabolic reactions require energy, so they are considered what type of reaction? A:

OPTIONS:
- autotrophic
- exothermic
- hydrostatic
- endothermic

A: endothermic

Answer the following question given this paragraph: Molds and casts are another way organisms can be fossilized. A mold is an imprint of an organism left in rock. The organism's remains break down completely. Rock that fills in the mold resembles the original remains. The fossil that forms in the mold is called a cast ( Figure below ). Molds and casts usually form in sedimentary rock. With compression ( Figure below ), an organism's remains are put under great pressure inside rock layers. This leaves behind a dark stain in the rock. Q: Molds and casts usually form in which type of rock? A:
OPTIONS:
- igneous
- metamorphic
- crystalline
- sedimentary
sedimentary
