Answer the following question given this paragraph: During mitosis , the nucleus divides as the chromosomes are equally separated. One nucleus becomes two nuclei, each with an identical set of chromosomes . Mitosis is followed by cytokinesis , when the cytoplasm divides, resulting in two cells. After cytokinesis, cell division is complete. The one parent cell (the dividing cell) forms two genetically identical daughter cells (the cells that divide from the parent cell). The term "genetically identical" means that each cell has an identical set of DNA, and this DNA is also identical to that of the parent cell. If the cell cycle is not carefully controlled, it can cause a disease called cancer in which the cells divide out of control. A tumor can result from this kind of growth. Q: The cytoplasm divides during what process? Choices: - metamorphosis - osmosis - genesys - cytokinesis A:
cytokinesis
Answer the following question given this paragraph: A familiar liquid is mercury metal. Mercury is an anomaly. It is the only metal we know of that is liquid at room temperature. Mercury also has an ability to stick to itself (surface tension) a property all liquids exhibit. Mercury has a relatively high surface tension, which makes it very unique. Here you see mercury in its common liquid form. Q: What is the only metal that is liquid at room temperature? Choices: - hydrogen - gas - water - mercury A:
mercury
Q: Answer the following question given this paragraph: Chromosomal disorders also occur when part of a chromosome becomes damaged. For example, if a tiny portion of chromosome 5 is missing, the individual will have cri du chat (cat's cry) syndrome. These individuals have misshapen facial features, and the infant's cry resembles a cat's cry. Q: Which chromosome is associated with cri du chat syndrome? Choices: - collagen 5 - genome 5 - spore 5 - chromosome 5 A:
A: chromosome 5
Question: Answer the following question given this paragraph: Figure 11.35 (a) Capillary action depends on the radius of a tube. The smaller the tube, the greater the height reached. The height is negligible for large-radius tubes. (b) A denser fluid in the same tube rises to a smaller height, all other factors being the same. Q: What domain-level category of cells can contain more than 1000 times the dna found in a typical bacterial cell? Choices: - chromosomes - mutations - genetic - eukaryotic A:
Answer: eukaryotic

Answer the following question given this paragraph: The kidneys are responsible for removing excess H+ ions from the blood. If the kidneys fail, what would happen to blood pH and to hemoglobin affinity for oxygen? Factors That Affect Oxygen Binding The oxygen-carrying capacity of hemoglobin determines how much oxygen is carried in the blood. In addition to P O , 2 other environmental factors and diseases can affect oxygen carrying capacity and delivery. Carbon dioxide levels, blood pH, and body temperature affect oxygen-carrying capacity (Figure 39.20). When carbon + dioxide is in the blood, it reacts with water to form bicarbonate (HCO 3 ) and hydrogen ions (H ). As the level of carbon dioxide in the blood increases, more H+ is produced and the pH decreases. This increase in carbon dioxide and subsequent decrease in pH reduce the affinity of hemoglobin for oxygen. The oxygen dissociates from the Hb molecule, shifting the oxygen dissociation curve to the right. Therefore, more oxygen is needed to reach the same hemoglobin saturation level as when the pH was higher. A similar shift in the curve also results from an increase in body temperature. Increased temperature, such as from increased activity of skeletal muscle, causes the affinity of hemoglobin for oxygen to be reduced. Diseases like sickle cell anemia and thalassemia decrease the blood's ability to deliver oxygen to tissues and its oxygencarrying capacity. In sickle cell anemia, the shape of the red blood cell is crescent-shaped, elongated, and stiffened, reducing its ability to deliver oxygen (Figure 39.21). In this form, red blood cells cannot pass through the capillaries. This is painful when it occurs. Thalassemia is a rare genetic disease caused by a defect in either the alpha or the beta subunit of Hb. Patients with thalassemia produce a high number of red blood cells, but these cells have lower-than-normal levels of hemoglobin. Therefore, the oxygen-carrying capacity is diminished. Q: What are responsible for removing excess h+ ions from the blood? Choices: - liver nodes - intestinal walls - stomach chambers - kidneys A:
**Answer**
kidneys

Answer the following question given this paragraph: Fossil fuels include coal, oil, and natural gas. Fossil fuels are the greatest energy source for modern society. Millions of years ago, plants used energy from the Sun to form carbon compounds. These compounds were later transformed into coal, oil, or natural gas. Fossil fuels take millions of years to form. For this reason, they are non-renewable. We will use most fossil fuels up in a matter of decades. Burning fossil fuels releases large amounts of pollution. The most important of these may be the greenhouse gas, carbon dioxide. Q: Millions of years ago, plants used energy from the sun to form what? Choices: - fossil fuels - evolution - greenhouse gases - carbon compounds A:
**Answer**
carbon compounds
