Answer:

Answer:  B. The release of calcium ions causes myosin and actin to attach to each other. This statement best describes a cause and it's effects that occur during the process of muscle contraction.

Muscle contraction can be explained by sliding filament theory.  

1. Activation of muscles: the motor nerve generates an impulse to transfer signals from neurons to neuromuscular junction. This stimulates sarcoplasmic reticulum to release calcium into the muscle cells.

2.Contraction of muscles:  calcium in the muscle cells binds with troponin causes actin and myosin to bind. Actin and myosin in the muscle binds and contract by utilizing ATP as a source of energy.

What makes a successful roller coaster
kolezko [41]
<span>This is a great question and I would love to hear what a roller coaster designer / engineer thinks makes a successful roller coaster. Until they show up, though, you've just got me.For me a successful roller coaster is one that fills me with dread as it makes the slow climb up the track, and then converts that dread into pure adrenaline as it takes me down and around. It's the one that makes your stomach drop as you're in freefall and makes your heart skip a beat as you take a corkscrew loop. Some roller coasters are open at the bottom so your legs dangle off. Some go backwards through a corkscrew. Those are fun additions.What I'm saying is that a good roller coaster is one that floods you with emotions as you're riding it - think about the Mummy ride at Universal Studios. It's not a particularly crazy coaster as far as thrill rides go, but the design of the ride itself is meant to fill you with anxious dread as you wait for something to happen and then launches you at breakneck speed when you least expect it. That's a good roller coaster, and I'm not even sure you'd actually call it a roller coaster.Well that's me ^.^ I hope this helps</span>
