What causes muscle contraction?
Muscle contraction in initiated by an action potential sent from the brain or spinal cord to the axon terminal of a motor neuron. Calcium then goes into the axon terminal which causes the release of the neurotransmitter acetylcholine which binds to receptors on the plasmalemma. Calcium then diffuses into the sarcoplasm and binds to troponin. The troponin is then shifted to expose binding sites on the actin filament allowing for the linkage of actin and myosin. The the actin filaments are then pulled inward during shortening the sarcomere and resulting in muscular contraction :) I learnt this stuff in year 9
What do the phases in meiosis do?
Prophase: coiling + shortening of the DNA into rods. the nucleolus and the nuclearmembrane break down.Metaphase: chromosomes line up in the middle of the cell.Anaphase: Chromatids of each chromosome separateTelophase: spindle fibers disassemble. chromosomes uncoilCytokinesis: the pinching inward of cell membrane. Cleavageis formed. Micro-filaments aid in splitting the cell.
What is the protein filament that slides inward toward the middle of a sarcomere during a muscle contraction?
Actin
What condition in which the lower eyelid turns inward causing the eyelashes to come into contact with the conjunctiva?
entropion!
What is the difference between fall in demand and contraction in demand?
A contraction in demand is caused by an increase in Price and illustrated by a movement up the demand curve. A decrease in demand is caused by any non-price factor (e.g. advertising, tastes and preferences and price of substitute goods) and is illustrated by an inward shift in the demand curve.
Does low pressure move inward or outward?
Inward!
Where can you get cheap inward forks?
wat does inward mean?!
After the can is heated and the lid was put on the can collapsed why did the can collapse?
The hot air inside the can cooled after the lid was put on. Cooling air contracts, pulling the can's parts inward, causing the collase.
Do low pressure systems move inward or outward?
inward

What is Direct Inward Dialing (DID)?
Direct inward dialing is known as DID
What is the difference between contraction in demand and decrease in demand?
A contraction in demand is caused by an increase in Price and illustrated by a movement up the demand curve. A decrease in demand is caused by any non-price factor (e.g. advertising, tastes and preferences and price of substitute goods) and is illustrated by an inward shift in the demand curve.
