Answer:
The correct answer is option a. "the cells will shrink due to water loss by the cell".
Explanation:
Cells placed in a hypertonic solution will shrink due to water loss by the cell. An hypertonic solution has a high content of solutes dissolved, which makes it a solution with high tonicity. Water tends to move from a solution of low tonicity to a solution with high tonicity. As a result, cells placed in a hypertonic solution will start to loss their inner water and shrink, which causes its death.
Answer:
(A) speciation.
Explanation:
Shrinking of water bodies and development of deserts since the Pleistocene ice age produced new vacant niches that could be inhabited by organisms such as fishes. Production of new isolated streams, ponds, and springs allowed the fishes to occupy these new water bodies. Accumulation of genetic variations to become adapted to their new habitat resulted in the evolution of several new species of fishes with many different genetic traits. This represents speciation due to geographical isolation.
The very first microscope was made by Robert Hooke and was a simple looking microscope. It has been many years since then and technology has evolved more and more. Modern microscopes can see things so small they’re invisible to the human eye.
The study of cells will have evolved as well, with scientists discovering something new everyday that will go in future textbooks for future generations to learn.
The impact of the modern day microscope has helped so much with the study of cells.
