The figure below shows ocean currents. where will climate change slow the currents the most, causing colder temperatures, and why? a. along the eastern side of south america, because increased temperatures will slow the movement of the brazilian current and bring in cooler water b. along the kuroshio current, because it is carrying water north towards melting ice caps c. along the n. equatorial current, because climate change has its greatest effects at the equator d. along the northern coast of north america, because ice will melt in the arctic and slow the labrador and e. greenland currents that travel south

its b

explanation:

there is no change

the answer is: the „power stroke“ step.

muscle contraction can be divided into a few steps:

1. the release of ach (acetylcholine) in the synaptic cleft, binding of ach for its receptor and consequently opening of the ca channels.

2. the release of ca, binding of ca for the troponin

3. troponin shifting the tropomyosin, which was blocking the active site on the actin

4. myosin heads attaching to actin by breaking down atp to adp+ pi

5.   formation of the ‘cross-bridge’ on the active site of the actin filament by myosin head

6. “power stroke” -the cross bridge pulls actin, which slides over the myosin

9.     7. the release of adp completes the cross-bridge movement and atp attaches to myosin, breaking the actin-myosin cross bridge.
