SOVA2 [1]

<u>During </u><u>latent </u><u>phase of a muscle twitch chemical changes such as the release of calicum are according intracelluary as rthe muscles prepare for contractrion.</u>

What are the phases of a twitch contraction?

  • A single contraction is called a twitch. A muscle twitch has a latent period, a contraction phase, and a relaxation phase.
  • A graded muscle response allows variation in muscle tension.

What is a latent period ?

The amount of time that passes between an action potential being generated in a muscle cell and the beginning of muscular contraction.

What is a muscle twitch?

  • The fundamental reaction of a motor unit to a single stimulus is a muscle twitch. Muscle Twitch in three different states .
  • Excitation of the muscle fiber takes place during the latent phase, and calcium ions are released from the sarcoplasmic reticulum into the cell's cytoplasm.

What happens during latent period of muscle twitch?

  • A single muscle twitch consists of three parts. the contraction phase, the relaxation phase, and the latent period, often known as the lag phase.
  • The action potential reaches the muscle, and the latent period is the brief (1-2 msec) interval before tension is seen in the muscle.

An important challenge to traditional (pre-1860) ideas about species was the observation that seemingly dissimilar organisms, su
choli [55]

Answer:

these seemingly dissimilar organisms might have evolved from a distant

Explanation:

Evolution deals with history of organism survival on Earth.

The evolutionary biologists makes use of fossils as proves to give light to having a clear view of how species survived in past times.

Before the theory of natural selection by Charles Darwin, Evolutionary Biologists were filled with questions about why the type of skeletal structural specimens collected were equal and different in dissimilar organisms as it does not exhibit the links seen between these species.

The theory of evolution proposed the mechanism of divergent evolution as a solution to these questions.

Therefore, we conclude that "these seemingly dissimilar organisms might have evolved from a distant" is the right answer.
