Put the following events of excitation-contraction coupling in the correct order. a. Calcium ions bind to troponin molecules on the actin myofilaments. open choices for ranking
b. The T tubules carry the action potential to the interior of the muscle fiber. open choices for ranking
c. The troponin-tropomysin complex moves, exposing active sites on the actin myofilaments.
c. Calcium ions are released into the sarcoplasm. open choices for ranking
d. A nerve impulse causes ACh to be released at a neuromuscular junction.
e. The heads of myosin myofilaments bind to sites on the actin myofilaments, forming cross-bridges.

answer; i believe the correct answer is (anemia);

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.  

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
