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.

3: Desert
4: The tundra
5: All of the above
Answer:
The correct answer is-
1. Photosynthesis- Carbon dioxide is a reactant, Oxygen is a product, Carried out in plants, Produces usable energy source.
2. Respiration- Carbon dioxide is a product, Oxygen is reactant, Carried out in animals, Produces usable energy source.
Explanation:
Photosynthesis is a complex process which takes place in the green plants which synthesize the energy molecule called glucose. The reaction takes place in the presence of sunlight combining the carbon dioxide and water forming the glucose and oxygen gas.
Respiration is a complex process which involves the breakdown of the glucose molecule in the presence of oxygen and forming the energy molecule called ATP which is utilized in the metabolic reactions. The complex process releases carbon dioxide.
