The correct answer is arthropoda.
Phylum arthropoda includes animal which lack tissues. Arthropoda is termed as a proposed grouping of arthropods.
They are being characterized by their cuticle and jointed limbs which are made of chitin. Their brains are formed by fusion of ganglia and their brains are formed of fusion of different number of segments.
Arthropods contribute to supply of food in human either indirectly or directly as pollinators of crops.
Answer:
Molecular, Microscopic, Cell, Tissue and Organ levels
Explanation:
The natural strength production needed for skeletal muscle to function occurs at the molecular level. You can develop a better knowledge of the properties of cells and tissues by simply studying the molecular systems common to the cells in question. The different muscular level down to myofilaments are:
-
Molecular level — actin and myosin
- Microscopic level — sarcomere and myofibrils
- Cell level — myoblasts and myofibers
- Tissue level — neuromuscular intersections and fascicles
- Organ level — The key skeletal muscles of the body
