In the thylakoid membranes
Answer:
Hiya there!
Explanation:
ATP then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site. ATP can then attach to myosin, which allows the cross-bridge cycle to start again; further muscle contraction can occur.
acetylcholine
: Skeletal muscle contraction and changes with exercise. (A) Neurotransmitter (acetylcholine, ACh) released from nerve endings binds to receptors (AChRs) on the muscle surface.
The muscle contraction cycle is triggered by calcium ions binding to the protein complex troponin, exposing the active-binding sites on the actin. As soon as the actin-binding sites are uncovered, the high-energy myosin head bridges the gap, forming a cross-bridge.

Hope this <em><u>Helped!</u></em> :D
Answer: In Stage 4 of the Demographic Transition Model birth rates and death rates are both low, stabilizing total population growth. The decline in both birth and death rates of most Stage 4 countries have been attributed to strong economies, highly educated citizens, ample healthcare systems, the migration of people from rural communities to cities (Bulgaria)
Explanation: i dont know if it's correct to them
The answer is urticaria (also known as hives).
The first reason was that his theory of continental drift was just too weak for most geologists to accept. Even though he believed the supercontinent that broke up into different continents moved, he did not have a clear explanation to how the continents moved. The other reason is that some of his explanation clashed with ideas that were widely accepted in the science communities. He used similar fossils from different continents to back up his theory of continental drift. However, at that time, many scientists that had observed similarities in fossils in places like South America and Africa believed there were similar fossils in different continents because of a land bridge that were formed by two continents.
Many science communities believe that land bridges allowed migration of many different species and even people to one place to another by large bodies of water frozen by low temperature known as ice age.
