Answer the following question given this paragraph: Prokaryotic organisms reproduce asexually by binary fission , a process that produces identical offspring ( Figure below ). In asexual reproduction , a single parent produces genetically identical offspring. As prokaryotes do not have a nucleus, and have only one circular chromosome, they do not need to reproduce by the same mechanism as eukaryotic cells; mitosis does not exist in prokaryotic cells . Prokaryotic cell division is a much simpler process. In prokaryotic cell division, after the single chromosome is copied, the cell grows larger. Eventually the two chromosomes separate and move to opposite ends of the cell. Newly formed cell membrane then grows into the center of the cell, separating the two chromosomes, and forming two genetically identical daughter cells. Some eukaryotic organelles, such as mitochondria and chloroplasts, also divide by binary fission. Q: How do prokaryotic organisms reproduce asexually? Choices: - mitosis - residual fission - kinetic fission - binary fission A:
binary fission
Answer the following question given this paragraph: The cardiovascular system is the system of organs that delivers blood to all the cells of the body. It's like the body's lifeline. Without the cardiovascular system circulating your blood, you couldn't survive. Q: What system of organs delivers blood to all cells of the body? Choices: - gastrointestinal - respiratory - integumentary - cardiovascular A:
cardiovascular
Q: Answer the following question given this paragraph: Partly movable joints allow only very limited movement. Bones at these joints are held in place by cartilage. The ribs and sternum are connected by partly movable joints. Q: What are the bones in partly movable joints held in place by? Choices: - socket - tendons - collagen - cartilage A:
A: cartilage
Question: Answer the following question given this paragraph: The term carbohydrate comes from the fact that the majority contain carbon, hydrogen, and oxygen in a ratio of 1:2:1, making for an empirical formula of CH 2 O. This is somewhat misleading because the molecules are not actually hydrates of carbon at all. Carbohydrates are monomers and polymers of aldehydes and ketones that have multiple hydroxyl groups attached. Q: What contains carbon, hydrogen, and oxygen in a ratio of 1:2:1? Choices: - helium - sodium - magnesium - carbohydrate A:
Answer: carbohydrate

Answer the following question given this paragraph: Figure 10.1 The mention of a tornado conjures up images of raw destructive power. Tornadoes blow houses away as if they were made of paper and have been known to pierce tree trunks with pieces of straw. They descend from clouds in funnel-like shapes that spin violently, particularly at the bottom where they are most narrow, producing winds as high as 500 km/h. (credit: Daphne Zaras, U. National Oceanic and Atmospheric Administration). Q: What descend from clouds in funnel-like shapes that spin violently, producing powerful winds? Choices: - currents - rains - hurricanes - tornadoes A:
**Answer**
tornadoes
Answer the following question given this paragraph: Figure 13.13 The Cerebellum The cerebellum is situated on the posterior surface of the brain stem. Descending input from the cerebellum enters through the large white matter structure of the pons. Ascending input from the periphery and spinal cord enters through the fibers of the inferior olive. Output goes to the midbrain, which sends a descending signal to the spinal cord. Q: The cerebellum is associated with what major human organ? Choices: - bladder - liver - heart - brain A:
brain
