The borders (coastlines) of the continents underwent a number of changes
since the split. Often, chunks of land were washed away with water,
slowly or in bigger portions. The coast was generally "smoothed" by the
ocean currents too, and in some places more land was added with the
material that the ocean currents brought.
Then, the tectonic plates continue to move, so this adds to the changes of the shape of the continents.
Answer:
a state of sustained partial contraction
Explanation:
Simply said, muscle tone means that there is a sustained tension in a muscle wile in a determinate posture. The muscle tone enable us to mantaing our bodies in a posture fit for resting or for also working, like sitting, being stand up or in a couch or sleeping. The changes in the muscle tones make us able to move. So contractions will follow depending what activity we are engaged on, as a continous and passive partial contraction of muscles change following changes in direction.
Muscle tones have contractions that do not produce enough tension to move, buy they keep it tense and firm.
Thererefore the tension is balanced and resting muscle tone balances bones and joints.
See below :)
In physiology, medicine, and anatomy, muscle tone (residual muscle tension or tonus) is the continuous and passive partial contraction of the muscles, or the muscle's resistance to passive stretch during resting state. It helps to maintain posture and declines during REM sleep.
Answer:
There are 2 alleles, a recessive allele and a dominant allele. The weaker allele is the recessive allele.
The most likely cause of the beak variation is the food source of the finch, the break size and shape was adapted to most likely have easier and better access to food. <span />
