How does artificial selection provide evidence for evolution by natural selection
Cloud [144]

Answer:

Natural selection is one of the mechanisms by which an organism evolve. In the natural selection when the trait of an organism allows the organism to grow and reproduce in an environment and nature selects it, it is then passed on to the generations and become permanent.

Artificial selection is also one of the mechanism of evolution in which instead of nature, the selection is made by humans like the breeding experiments on dogs and plant crops.

The artificial selection and natural selection are interlinked as in the artificial selection the trait selected by the humans were also selected by nature like the case of crops, the crossing between desired plants produced results which were useful to the humans but grew and reproduced only when the environment selected it to grow and reproduce.

How does the process of smooth muscle contraction differ from contraction in skeletal muscle?
Lana71 [14]

Similar to the other types of muscle, smooth muscle contraction is caused by the sliding of myosin and actin filaments over each other. Calcium initiates contractions in a different way in a smooth muscle than in a skeletal muscle.

Smooth muscles use less energy to generate the given amount of force, can substain contractile force without fatigue & uses calcium from the sarcoplasic reticulum & extracellular space.
