luda_lava [24]

Answer:

A flat sheet of connective tissue that extends beyond the muscle fibers to attach the muscle to bone is a TENDON.

Explanation:

Tendon can be described as a fibrous connective tissue which functions mainly to attach muscles to bones hence, playing a major role in the movement of the bone or structure. Tendons also function to connect muscles to other structures like the eye ball.

Contrary to the tendons, ligaments are also fibrous connective tissues which are involved in the attachment of bone to bone. Hence, ligaments play major role in holding the structures and keeping them stable.

Using the idea of concentration gradient explain why the purple colour of potassium permaganate gradually spreads throughout the
NNADVOKAT [17]

The purple color of potassium permanganate gradually spreads throughout the water in the jar by the process of diffusion.

  • Diffusion is the process of movement of a substance from the region of higher concentration to the regions of lower concentration. Diffusion occurs in liquids as well as gases.
  • Potassium permanganate is a purple color compound, when it is added in a jar of water it spreads throughout the water by the virtue of diffusion.
  • The concentration of potassium permanganate is higher at one point and the other regions in the jar have its nil or low concentrations initially, this leads to the set up of a concentration gradient.
  • As time passes diffusion occurs and the particles of potassium permanganate keep on migrating to the regions of low concentration until the concentration is uniform throughout the jar. Ultimately, it spread throughout the jar making the water purple.

Consider the factors that affect muscular strength. Read each scenario and identify whether each would result in a stronger or w
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.
