anygoal [31]

Answer: 26.75 meters.

2πr = 84

2 * 3.14 * radius = 84

radius = 84/6.28

r= 13.375

So the diameter will be 13.375 + 13.375 which is 26.75 meters.

Why is special creation not considered a scientific explanation for the diversity of life on earth?
Rufina [12.5K]
Special Creation is a term that can be interpreted a number of ways, just as evolution can. One interpretation called Young Earth Creationism, YEC, erroneously discounts much of the physics, chemistry, biology and wealth of data that science has observed. Most pronounced is the proposition that the universe is only ~<10 k years old. Because of this, it is not considered scientific. When applied to the diversity of life, YEC's believe all life is the result of special creation events made in less than one week of time, countering the long times for organism development and progression that science has observed. YECs account for the origin of all life through special creation, while science presently has no explanation naturalistically for the origin of life. YECs do not recognize evolution, science presently considers evolution through natural selection, as the source of all living entities. While evolution is fatally flawed in explaining how life has progressed, YECs compress all life development, despite the long period of time indicated scientifically.

An alternate special creation model accepts the long era of Earth formation and life's creation and progression, attributes the origin of life to God's intelligent designed cellular functionality, considers all of the fossil evidence showing stages of radiation events, stasis and extinction as God bioformed the Earth using common design for the eventual consciously intelligent humans.

Which dance resulted from the development of a culture technique for muscle cells
Whitepunk [10]

Rhythm Salsa resulted from the development of a muscle cell culture technique.

<h3>How to do cell culture?</h3>

To obtain a cell culture, it is necessary to disaggregate the original tissue, which can be by mechanical force or enzymatic process. These cells are grown in an adherent layer in a single layer (monolayer) or in organoid format (3D culture) or in suspension.

With this information we can conclude that rhythm Salsa resulted from the development of a muscle cell culture technique.
