Consider the factors that affect muscular strength. Read each scenario and identify whether each would result in a stronger or weaker muscle contraction. 1- Potassium accumulate in the sarcoplasm
2- Increase in muscle belly circumference
3- Lesser proportion of motor neurons to muscle fibres
4- Begin contractions with muscle already 50% contraction
5- Lower sarcoplasm pH
6- Increased stimulus frequency.
7- Circular arrangement of muscle fascicles
8- increased requirement.

Muscles are required in breathing, talking, running, walking, and any body movement. Actin and myosins are protein filaments present in muscle cells that help to contract and relax or change the shape of muscles. Muscles are responsible for the movement or motion of organisms. Joints are the connection between two or more bones. Most joints are mobile.

Muscle strength is determined by several factors. Some of those are the physical shape, size, and innervation of the muscles.  

Weak contraction

Stronger contraction

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
