1. There are approximately 14 species of bay grasses in Chesapeake Bay. Bay grasses provide a habitat for birds, fish, and shellfish. Most bay grasses grow
attached to the bottom substrate in shallow water. Scientists estimate that the
area covered by bay grasses once exceeded 600,000 acres. In 1978, scientists
learned that bay grasses only covered 41,000 acres. Scientists began working to
improve environmental conditions in the bay. They replanted bay grasses in some
areas. They set a goal of having 110,000 acres of bay grasses by the year 2000.
The data collected from yearly surveys of bay grasses is shown in the graph
below. Evaluate the success of this project. In your response, be sure to: A.
predict the most likely value for the missing data in 1988; explain your answer. B.
describe the trend in the area covered by bay grasses in Chesapeake Bay from
1984 go 2000; use specific information from the graph to support your answer.
C. suggest possible reasons for the changes in the graph between 1993 and
1995. D. describe ways that individuals can help in the restoration of bay grasses.

common management practices in dairy and poultry farming are: (i) proper shelter facilities and their regular cleaning. (ii) some basic hygienic conditions such as clean water, nutritious food, etc. (iii) animals are kept in spacious, airy, and ventilated place.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
