That's a very good question!! That would have to go along with the process of weathering and erosion. Basically how the heat, weather, and he pressure of the Earth forms land . Mount Everest was formed when India plate moved rapidly northwards towards Euro Asia plate.
Hope this helps!!
Answer:
Power stroke (myosin head bends) coupled with the release of ADP and phosphate
Explanation:
Muscle contraction results from myosin heads adhering to actin and attracting it inwards. It uses ATP. Myosin adhers to actin at a binding site of its globular actin protein and adheres at another binding site for ATP (hydrolyzed ATP to ADP, Pi and energy)
ATP binding prompts myosin to detach from actin, ATP is changed to ADP and inorganic phosphate, Pi by ATPase. The energy formed at this process orientates myosin head to a “cocked” direction.
The myosin head goes in the direction of the M line, holding the actin with it in the process causing the filaments to orientate nearly 10 nm in the direction of the M line--- power stroke (force is produced), the sarcomere reduces in length and the muscle contracts.
Note: The power stroke is seen when ADP and phosphate disattaches itself from the myosin head.
At the terminal point of the power stroke, the myosin head as low-energy, followed by ADP release.
The attached image shows the cross-bridge muscle contraction cycle, which is activated by Ca2+ sticking to the actin active site. And how actin moves in relation to myosin.
<h2>Some bacteria are facultative anaerobes, which usually produce ATP by aerobic respiration but are also capable of switching to fermentation when there is a lack of _____OXYGEN____ in their environment. </h2>
(a) Agree
It is probable that less sticklebacks will have pelvic spines in Bear Paw Lake, as it is a smaller region without as much competition. Predators may be much lower in such an environment, eliminating a need for such protection. In the ocean, however, there is much biodiversity and competition, so the fish need pelvic spines to protect themselves.
A positive charge is created in the cell that travels down it does a nerve
impulse begin in a neuron. Thus, the correct option is A.
<h3>
How the neuron get stimulus?</h3>
When a neuron receives a chemical stimulation, a nerve impulse is formed. The electrical action potential of the nerve impulse passes along the axon membrane to the axon terminal. Neurotransmitters are released at the axon terminal, which transfer the nerve impulse to the next cell.
The resting potential of a neuron is the electrical differential across its membrane. The sodium-potassium pump, a transport protein, creates the resting potential. This protein generates a positive charge by moving a high number of sodium ions (Na+) outside the cell.
