Vestigial structures are considered evidence since scientists believe they are structures that were once used by a species ancestors but are no longer needed. They do not impair the organisms in any way, so there is no need for evolution to get rid of them. Vestigial structures are anatomical features that no longer seems to have a function or purpose in the current form of an organism of the given species. Examples are wisdom teeth, the muscles of the ear, the appendix, the tail bone among others in human.
Answer: a) rarely occurs in highly connected metapopulations
Answer:
the answer is c, polarity of water molecules
Explanation:
The answer is that a unicellular organism would swell and burst.
In a hypotonic solution <span>the </span>water concentration<span> of the cell's cytoplasm is </span>lower<span> then that of the hypotonic solution. If unicellular organism is exposed to a hypotonic solution, the water from the solution will enter the organism by the process called osmosis. The aim is to balance water concentration on the inside and outside of the organism. But, that water entering the cytoplasm of the cell will make pressure on the cell membrane. If the </span><span>excess water cannot be removed from the organism, it will swell and burst.</span>
Answer:
I believe the cell is a plant cell
