Answer:
Muscle contraction occurs when the thin actin and thick myosin filaments slide past each other. It is generally assumed that this process is driven by cross-bridges which extend from the myosin filaments and cyclically interact with the actin filaments as ATP is hydrolysed.
Answer:
One thing that a scientist might ask about the movement of carbon dioxide through the whale and its surrounding is “how did the whale get the carbon dioxide?”. Another thing that a scientistmay ask about this is “how does the carbon dioxide affect the ecosystem?”
Answer:
B. 4.0 Okta
Explanation:
Okta is a measurement of cloud elevation in metrology. NASA used this metric to identify the cloud elevation. The cloud elevation reached to 4.0 okta during the year 2002. High elevation ecosystem is vulnerable. The change in okta does not produces new substance and the elevation of cloud is changed.
this means that specific reaction involving specific substance are catalyzed
