| 1. | Subsequently the phages evolved contractile or short tails and elongated heads.
|
| 2. | Conversely, increasing extracellular Ca 2 + concentration enhances contractile force.
|
| 3. | The taproot is contractile, and tends to pull crown downwards.
|
| 4. | The ostrich heart is a closed system, contractile chamber.
|
| 5. | Z-disks are the point of contact for the contractile proteins.
|
| 6. | Most of these have modified posterior kinetosomes which secrete a contractile stalk.
|
| 7. | Engulfment of material is facilitated by the actin-myosin contractile system.
|
| 8. | In novice hypertrophy and metabolic fatigue becomes the factor limiting contractile force.
|
| 9. | Its behavior is different in contractile and pacemaker heart cells.
|
| 10. | Calcium is pumped away from the contractile apparatus and the muscle relaxes.
