The evolutionary effects of the genetic drift are the greatest when the population is small.
In small populations, genetic drift can significantly change the frequencies of the alleles and affect the genetic structure of the population. In big populations, the effects of the genetic drift are small and insignificant.
Answer:
C, a long absolute refractory period.
Explanation:
Tetanus is not possible in cardiac muscle tissue because cardiac cells have longer action potentials and a very long refractory period compared to other cells. This helps prevent the heart from cramping and seizing up.
Answer:
During METAPHASE the chromosomes line up along the equatorial plate.
Answer:Prokaryotic cells make up the organisms found in the two Kingdoms of life known as Bacteria and Archaea.
there are cells without a nucleus, which are called prokaryotes. They are a group of organisms which lack a cell nucleus. The organisms with this type of cell are called prokaryotic organisms or prokaryotes. These organisms were the first to be found in the planet Earth.
A prokaryotic cell is mostly composed of a plasma membrane, cell wall, cytoplasm, genetic material in the nucleoid and ribosome. They are single-celled and are much smaller compared to eukaryotic cells. They exist in different shapes including spherical, rod, flat, coccus, spirochete, and some are also shapeless, not having a consistent shape.
Explanation:
C. Ice is less dense than water which means water condenses when it freezes allowing the ice in a lake to float on top of the water preventing the water below from freezing.
