Answer:
yes all coll have ribosomes
Answer:
The correct answer is - Protein molecule.
Explanation:
The cell membrane is the outer membrane of the cell that differentiates the external environment from the internal components of the cell. The cell membrane is made up of two major components that are lipids and proteins.
Proteins are present as channels and in the form of membrane proteins in between the lipid bilayer. Protein is the molecule that denatured or destroyed at high temperatures such as 70 degrees.
(ATP) is comprised of an adenine ring, a ribose sugar, and three phosphate groups.

The name of the structure labeled as A is 'myosin'. Moreover, the name of the structure labeled as B is 'actin'.
A sarcomere is the basic unit of muscle contraction. This unit is defined as the region between two Z-lines.
Band A is a central band composed of the thick filaments of myosin.
Moreover, the sarcomere also has two halves of a band known as I-band, which consists of thin filaments of actin.
Muscle contraction is caused by the interaction between actin and myosin protein filaments in the sarcomeres.
