1.What is a plate boundary?
2.What are three interactions can plates have? these are the three major types of plate boundaries.
3. In general what does the theory of plate tectonics explain?
Answer:
1. Plate boundaries are the edges where two of the Earth's plates meet
2. The three types of plate interacts include divergent boundaries, convergent boundaries, and transform boundaries.
3. This is the theory that the Earth's crust is separated into plates that move over the Earth's mantle. As stated, they can move in ways such as coming together, spreading apart, and interacting at boundaries all over the planet, which can cause things such as volcanos and earthquakes. Scientists created this theory as a way to explain why certain events like these are caused.
Answer:
THE EDGES WHERE TWO OF THE EARTH'S PLATES MEET.
DIVERGENT, CONVERGENT,TRANSFORM
EARTH'S CRUST IS SEPARATED INTO PLATES THATS MOVE OVER THE EARTH'S MANTLE
What is the effect of an increased concentration of calcium ion in the sarcoplasm?
Answer:
When calcium concentration increases during depolarization, it shifts the conformation of troponin and tropomyosin, and actin is able to associate with myosin. As calcium is taken up again by the sarcoplasmic reticulum the muscle cell relaxes.
The effect that can be associated with increase in concentration of calcium ion in the sarcoplasm is :
Changing of shape and position of tropomyosin.
Can also cause muscles stiffness.
When the Ca2+ concentration become high in the sarcoplasm, there would be change in the position of tropomyosin as result of the binding effect of Ca2+ binds on troponin.Then the tropomyosin will be moved away from myosin binding sites on actin, then a cross bridge will be formedHowever, the effect if this on muscles is muscles stiffness.
