Answer:
Time taken by space shuttle = 714.28 m/s
Explanation:
Given:
Distance cover by space shuttle = 500,000 meter
Speed of space shuttle = 700 m/s
Find:
Time taken by space shuttle
Computation:
Time taken = Distance / Speed
Time taken by space shuttle = Distance cover by space shuttle / Speed of space shuttle
Time taken by space shuttle = 500,000 / 700
Time taken by space shuttle = 714.28 m/s
The Silurian period occurred before the Neogene period.
I hope this helps.
Answer:
<u>Once the myosin-binding sites are exposed, and if sufficient ATP is present, myosin binds to actin to begin cross-bridge cycling. Then the sarcomere shortens and the muscle contracts. In the absence of calcium, this binding does not occur, so the presence of free calcium is an important regulator of muscle contraction.</u>

Answer:
b. Covalent bond between R groups
Explanation:
Disulfide bridge also known as disulfide bond or dicysteine bond is a type of interaction in which two cysteines of proteins come in close proximity with each other and form covalent bond with their functional (R) groups. The purpose of this bond is to stabilize the tertiary structure of a protein and make it more compact.

The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time.
