Answer: Seems like Group B had the most accurate measurements.
Hope that helps :)
Options for the question have not been provided. They are as follows:
A. collagen fibers.
B. gelatinous mass.
C. actin and myosin fibers.
D. keratin fibers.
E. fibroblast cells.
Answer:
C. actin and myosin fibers.
Explanation:
Muscle cells or myocytes are unique because they have an abundant amount of actin and myosin fibers. These fibers are responsible for the contraction and relaxation of muscles. They are protein filaments, myosin is called thick filament and actin is called thin filament. Muscle cells not only have an abundant number of these fibers, but also they are organized properly in a fixed pattern. Each myosin is surrounded by actin and each actin is surrounded by myosin. They slide over each other in a fixed pattern to cause muscle contraction.
Answer: Option C) Vestigial
Explanation:
A vestigial parts are the body parts that are shared with a common ancestor specie and have been modified to work in different ways because of changes in the mode of life.
Examples of vestigial parts in humans include:
- the appendix, which functions as caecum in herbivores
- mammary glands, which is well developed in women but not so developed in men
