How can plastics in the ocean impact human health?
Thepotemich [5.8K]
I believe the plastics in the oceans are harmful to ocean organisms and human health when people consume ocean organisms. Each plant and animal play its own role in sustaining the world's largest ecosystem. However, due to the ever-growing waste of humanity, we are gradually upsetting this balance. As a global community, we are unable to effectively implement sustainable habits. We produce a lot garbage, and all that garbage has to end up somewhere.

nlexa [21]

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

  • Potassium accumulates in the sarcoplasm.
  • Contracted lower sarcoplasm pH.
  • Begin contraction with muscle already 50%.
  • The circular arrangement of muscle fascicles.

Stronger contraction

  • Increase in muscle belly circumference.
  • A lesser proportion of motor neurons to muscle fibers.
  • Increased recruitment.
  • Increased stimulus frequency.
