The
answer is ‘they create tension by pulling toward opposite poles’. Kinetochores change
between persistent phases of movement towards the pole (poleward) or inversed
(anti-poleward), which are coupled with alternating states of kMTs (kinetochore
microtubules) depolymerization and polymerization, respectively. A low tension
at kinetochores promotes change towards kMTs depolymerization, and high tension
promotes change towards kMTs polymerization.
Answer:
C. 25°
Explanation:
Prepare a sketch such that the first line with points VRS intersect the line with points TRW at R where ∠WRS and ∠VRT are vertical angles.
Because line TW intersect line SV at R, then ∠WRV and ∠SRT are vertical angles.
The sum of ∠SRT and ∠VRT =180°
Thus (25x +30)°+(5x)° =180°
25x +30° +5x =180°
30x= 180°-30°
30 x = 150°
x= 150/30
x= 5°
∠SRT = 25x+30 = 25*5 +30 =155°
∠WRS= 180°-155°=25°
Sometimes when the moon orbits Earth, it moves between the sun and Earth. When this happens, the moon blocks the light of the sun from reaching Earth. This causes an eclipse of the sun, or solar eclipse. During a solar eclipse, the moon casts a shadow onto Earth.
