Sex linked inheritance is a trait that is passed through generations in which is linked directly to an individuals gender or sex. most of the time sex linked inheritance is seen in males however it can be viewed in females.
A sudden and violent movement of the ground sometimes causing great destruction as a result of movements within the earths crust or volcanic action.
Given data:
● Angular velocity of the turntable ω = 33 rev/min
Therefore,
ω = 33 rev/min
ω = 33rev/min × 2π rad/rev × 1 min/60 sec = 3.45 rad/s
● The distance of the watermelon seed from the axis of rotation r = 7.8 cm = 0.078 m
● μs = the coefficient of static friction
Section a:
The seed is undergoes circular motion and it is been effected by centripetal acceleration.
ac = rω^2
ac = 0.078 × 3.45^2
ac = 0.9284 m/s^2
Therefore,
the centripetal acceleration of the seed is 9.274 m/s^2
Section b:
If the seed is observed not to slip at the course of the circular motion, then the supplied frictional force given by the seed and surface of turntable would at least be equivalent to the centripetal force working on the seed.
Centripetal Force = Frictional Force
mrω^2 = μsmg
μs = rω^2 /g
μs = 0.078 × 3.45^2
------------
9.81
μs = 0.09464
Thus,
the coefficient of static friction is 0.09464.
At neuromuscular junctions, a neurotransmitter called as acetylcholine if found. Botulinum toxin inhibits the transmission of acetylcholine at the synaptic junctions. Botulin toxin acts at presynaptic junctions and blocks the release of acetylcholine, leading to paralysis.
