1. Local endemic species often have small population sizes, placing them at particular risk of extinction because of their greater vulnerability to demographic and genetic ______________.

2. The ______________ of any particular possibility is referred to as its probability of occurrence.

3. The ______________ of conduction is greater if the diameter of the axon is large or if the axon is myelinated.

4. Most insects can fold their wings over their abdomen when they are ______________; but a few, such as the dragonflies and damselflies, keep their wings erect or outstretched at all times.

5. The labyrinth is a system of fluid-filled membranous chambers and tubes that constitute the organs of ______________ and hearing in vertebrates.

1. This being so, the myosin particles no longer repel each other and associate.

2. No rapid change in physical state of the myosin can be expected to be caused in this region, charges being balanced here much better than in the secondary zone.

3. We must always remember the level of the organization we are at when we study biological reactions.

4. What lends special interest to these relations is the possibility that these influences may work both ways.

5. What is noteworthy in that picture is the fact that everything that can be seen is round, indicating a globular shape.

6. Actin has a striking property of being capable of existing in globular as well as in fibrous form.

7. We can expect the thread to have unbalanced forces; otherwise it could not unite with myosin to form actomyosin.

8. To make the globules polymerize one must add a little salt.

9. The inner mechanism of polymerization seems to be rather complicated.

10. If oxidized, actin does not polymerize any more, but can be reactivated by reduction by ascorbic acid.

11. Another simple question we can study is that of temperature relations.

12. Another point we can study is ionic concentration, though we must bear in mind that conditions are very complex and difficult to interpret.

13. We are unable to fit this process into its proper place until we know whether muscle needs energy for its contraction or relaxation.

14. We must expect that the natural logarithm of these numbers, if plotted against the temperature, will give a straight line.

15. The material was cut into slices, each slice containing one sheet of parallel muscle fibers.

16. It is a matter of interesting speculation whether the process may be considered as isothermal.

17. We are accustomed to see enzymatic reactions increase their rate if we raise the temperature.

18. The physiological ionic concentration, corresponding to that of serum, marks a critical point.

19. It seems interesting to know whether this principle also applies to other processes, like that of oxidation.

20. Of particular interest is the relation between the primer DNA employed and the new DNA synthesized. It seems very likely that this reaction represents the principal, perhaps the only mechanism of DNA synthesis in the cell.

21. As yet nothing is known of the mechanism of the exchange, or even whether it is an essential concomitant of the replication process.
