Answer the following question given this paragraph: The cell found in greatest abundance in blood is the erythrocyte. Erythrocytes are counted in millions in a blood sample: the average number of red blood cells in primates is 4.7 to 5.5 million cells per microliter. Erythrocytes are consistently the same size in a species, but vary in size between species. For example, the average diameter of a primate red blood cell is 7.5 l, a dog is close at 7.0 l, but a cat's RBC diameter is 5.9 l. Sheep erythrocytes are even smaller at 4.6 l. Mammalian erythrocytes lose their nuclei and mitochondria when they are released from the bone marrow where they are made. Fish, amphibian, and avian red blood cells maintain their nuclei and mitochondria throughout the cell's life. The principal job of an erythrocyte is to carry and deliver oxygen to the tissues. Leukocytes are the predominant white blood cells found in the peripheral blood. Leukocytes are counted in the thousands in the blood with measurements expressed as ranges: primate counts range from 4,800 to 10,800 cells per l, dogs from 5,600 to 19,200 cells per l, cats from 8,000 to 25,000 cells per l, cattle from 4,000 to 12,000 cells per l, and pigs from 11,000 to 22,000 cells per l. Lymphocytes function primarily in the immune response to foreign antigens or material. Different types of lymphocytes make antibodies tailored to the foreign antigens and control the production of those antibodies. Neutrophils are phagocytic cells and they participate in one of the early lines of defense against microbial invaders, aiding in the removal of bacteria that has entered the body. Another leukocyte that is found in the peripheral blood is the monocyte. Monocytes give rise to. Q: What do erythrocytes carry and deliver to tissues in the body? A:
****
A: oxygen

Answer the following question given this paragraph: The generation of electricity is critical for the operation of nearly all aspects of modern society. The following diagram illustrates the types of fuels used to generate electrical power in the Unites States. In 2009, almost 45% of the power generated in the U. S. was derived from coal, with natural gas making up another 23% of the total. The third primary source of electrical energy is nuclear power, which accounts for approximately 20% of the total amount generated. All of these fuels give off energy in the form of heat. This heat is used to convert water into steam, which is then used to turn a turbine, thus generating electrical power. Q: This heat is used to convert water into steam, which is then used to turn a turbine, thus generating what? A:
****
A: electrical power

Answer the following question given this paragraph: The stratosphere is the layer above the troposphere. The layer rises to about 50 kilometers (31 miles) above the surface. Q: What is the layer above the troposphere? A:
****
A: stratosphere

Answer the following question given this paragraph: Evolution focuses on past life forms and how they turned into present life forms. The history of life on Earth demonstrates how the first cells formed, turned into simple life forms, and then became more complex plants and animals. The studies of Charles Darwin have reshaped and influenced all aspects of biology. The myriad evidence of evolution demonstrates the importance of the theory of evolution by natural selection. Lastly, the current focus on evolution demonstrates that evolution is a continuous and ongoing process that continues today. Q: Focused on evolution, the studies of what man have reshaped and influenced all aspects of biology? A:
****
A:
charles darwin
