Researchers investigated the effect of urea on the three-dimensional structure of a certain enzyme. the researchers dissolved the enzyme in an aqueous buffer solution and added urea to the solution. the enzyme did not appear to have a secondary or tertiary structure. the researchers carefully removed the urea from the solution and determined that the enzyme had the original secondary and tertiary structure again. based on the results of the experiment, which of the following statements best predicts the effect of urea on the enzyme’s function? 1. function will be disrupted by adding the urea and regained by removing the urea.2. function will be disrupted by adding the urea, but it will not be regained by removing the urea.3. function will be gained by adding the urea and disrupted by removing the urea.4. function will be unaffected by the addition and removal of the urea.

Chapter 11.1 & 11.2 notes section 11.1 1. every living thing has a set of ? inherited from its parents. 2. after becoming a ? , mendel spent several years studying ? and mathematics at the university of vienna. 3. during sexual reproduction, male and female reproductive cells join, a process known as ? . 4. pea flowers are normally ? , which means that sperm cells in pollen fertilize the egg cells in the ? flowers. 5. when mendel crossed plants with ? characters for the same trait, the resulting offspring had only one of the characters. 6. a ? is a specific characteristic, such as seed color or plant height, that varies from one individual to another. 7. filius and filia are the latin words for ? and ? . 8. the offspring of crosses between parents with different traits are called ? . 9.to mendel's surprise, all of the offspring had the character of only ? of the parents. 10. mendel's first conclusion was that biological inheritance is determined by ? that are ? from one generation to the next. 11. scientist calls the chemical factors that determine traits ? . 12. mendel's second conclusion is the ? . 13. the principle of dominance states that some alleles are ? and others are ? . 14. when mendel allowed the f1 plants to reproduce by self-pollination the traits controlled by ? alleles reappeared in about ? of the f2 plants in each cross.

Two students are working together on an experiment that measures the effect of different liquid fertilizers on the thickness of plants’ stems. which is most likely to result in the greatest amount of error in their scientific experiment? a.one student measures the plant stem widths by using calipers. the other student measures the widths of the same plant stems again by using a different pair of calipers. b.one student measures the plant stem widths by using calipers. the other student types the measurements as they are taken into a computer spreadsheet. c.one student weighs liquids for the experiment by using a calibrated scale. the other student weighs liquids for the experiment by using a different calibrated scale.

Consider the venn diagram of plant reproduction. where in this image, areas a - d, would you insert the picture of the orange lily?
