25 Questions

1. Consists of undifferentiated cells capable of quick growth and specialization. It is responsible for elongation of the stem.

2. Transparency - polarity - high specific heat - and density (lower density when solid than when liquid.).

3. Is made of stacked cells connected by sieve plates that allow nutrients to pass from cell to cell. They transport food made in the leaves (by photosynthesis) to the rest of the plant).

4. Covalent bonds

5. Occurs when an individual from an adjacent population of the same species immigrates and breeds with a member of a previously locally isolated group - resulting in a change in the gene pool.

6. The number of organisms in a given community - can be above or below the carrying capacity.

7. High temperatures

8. Protein synthesis

9. Are membrane-bound organelles that contain digestive enzymes that digest dead or unused material within the cell or materials absorbed by the cell for use.

10. A hydrogen bond involves the ________________ and can be easily broken.

11. Is when expression of genetic traits is determined by weather the trait is inherited from the mother or the father.

12. Is a packet of digestive enzymes that destroy cellular wastes.

13. The phyla composed of segmented worms.

14. Are produced when water passes through the cell membrane by osmosis from an area of higher concentration to an area of lower concentration - to equalize water concentration.

15. Anabolism

16. Contains organisms that are multicellular eukaryotes including molds and mushrooms.

17. Enzymes are usually __________ to certain reactions.

18. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.

19. The most recent and present era. It includes the radiation of flowering plants - the angiosperms.

20. Ended with the extinction of the dinosaurs.

21. Secretes insulin to lower blood sugar and maintain equilibrium. A person eats three candy bars. Within minutes this endocrine gland affects blood-glucose homeostasis.

22. Fossilized burrows from multicellular organisms begin to appear in the geological record approximately 700 million years ago during the Precambrian period. These multicellular animals had only soft parts and could not be fossilized.

23. Occurs when an individual learns not to respond to a particular stimulus - for instance when a stimulus is repeated many times without consequence.

24. States that where random mating is occurring within a population that is in equilibrium with its environment - the gene frequencies and genotype ratios will remain constant from generation to generation. It is a mathematical formula that shows why re

25. Synthesis
