What ions, ATP, and neurotransmitters are used in muscle contraction and where are they used??
vivado [14]

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.

Bacteria undergo mitosis and meiosis in order to reproduce and increase genetic recombination.
Salsk061 [2.6K]

Answer:

The correct answer is (b)-False

Explanation:

Bacteria do not undergo meiosis or mitosis to reproduce and increase its genetic recombination. To increase their genetic recombination bacteria take the help of horizontal gene transfer through which it gets the genetic material of another bacteria. This new gene helps bacteria to survive in the challenging environment.

Bacteria divide through binary fission in which one cell of bacteria divides into two equal daughter cell each having its genetic material because genetic material of parent cell segregate equally into both the cell.  

Therefore bacteria do not undergo meiosis or mitosis.
