The Z disc is the: Group of answer choices separation between sarcomeres. electrical voltage at which a muscle cell fires an act
ion potential. area of a sarcomere where only thick myofilaments are found. point where the axon and the sarcolemma meet. place where two cardiac muscle cells meet.
The structure of the muscle fibre is composed of many functional units called sarcomere which is interrupted by the discs called Z-discs.
These Z-discs are made of the alpha-actin homodimers which allow the actin filament allows to bind to it along with other proteins. The Z-discs since present at regular intervals in a muscle appears to separate the sarcomere and defines the boundaries of the sarcomere.
A population decrease in primary producers would affect the ecosystem negatively because everyone who ate the primary consumers would have a lack of food.
Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.
