Which of the following would be most effective as a feedback mechanism Reduced concentration of product Increased concentration of substrate A change in pH Temporary binding of a non-substrate molecule in the active site Which of the following statements is accurate in describing the activity of the lactase enzyme Lactase can function equally effectively at many different pH levels The shape of lactase does not change during the reaction Lactase is converted to glucose and galactose by the reaction One lactase enzyme can catalyze many reactions Look up and write in the following definitions as they apply to chemical reactions Catabolic a chemical reaction during which a larger molecule is being broken down into simpler forms while releasing energy Anabolic a chemical reaction during which simpler molecules are being put together into larger molecules with an energy cost Endergonic a chemical reaction during which a system absorbs energy from its surroundings, effectively some kind of work is being done upon a system.

    Mariella Hines is a 9 year-old African-American girl attending the 3rd grade in the JFK School. She was referred to the School Psychologist because she has recently become very withdrawn during class, refusing to speak to anyone, including her teacher and peers. Previously she seemed to have age-appropriate social skills, interacting well at school. Her withdrawal started suddenly. Mariella’s teacher, Mrs. Levine, called Mariella’s mother to find out more information, but her mother said that Mariella seems fine at home.…

    6. Briefly describe the two meiotic events that contribute to genetic diversity in a population. Each gamete (sex cell) is unique due to a process during meiosis called cross-over which (simplified) swaps around some genes to create unique chromosome combinations. meiosis helps to create a population that is not only physically and genetically different but also one, which is perfectly fit to survive.…

    Yes there was a change because with the starting snail population there was a great variation from 1-7. After the crab began eating only the snails with the thickest shells survived. The snails with the thinnest shells were eaten by the crab. Only snails with shell thickness 4-7 were left after the crab had their meal. The original snails with thickness 1-3 were eliminated from the population by the crab. The crab will usually try to expend as little enrgy as it can to maximaize its happiness so the snails with thinner shells will likely be targeted first and eventually eliminated.…

    I think that free earlobes is the dominant trait (Because none of the 20 people I surveyed had attached earlobes). I think that no hair on knuckles is the dominant trait (Because 75% of the people I that surveyed had it). I think that straight hair line is the dominant trait ( Because 75% of the people I that surveyed had it). I don't know whether straight hair or curly hair is the dominant trait (Because it was an even split). I think that no cleft chin is the dominant trait (Because 90% of the people I surveyed had it). I don't seem to exhibit any of the recessive traits shown here. I shared the same chin shape, earlobes and amount of hair on knuckles. I didn't exhibit any trait that was not exhibited in my parents. If an offspring exhibited a recessive trait that neither parent exhibited, it would mean that both parents carried it. I was surprised that none of the 20 people had attatched earlobes. Yes, It is possible that a recessive trait…
