That's true. There is little variety among organisms found in pools, pounds and lakes. Despite that fact that many ponds are seasonal, lasting just a couple of month (for exemple sessile pools) while lakes can exist for more than hundred years. Lakes and ponds have limited species diversity because they are often limited from each other and from other water sources like rivers, seas and oceans.
Isotonic solutions is the term used when the concentrations of solutes inside and outside a cell are in equilibrium.
Explanation:
The isotonic solution is one which have same osmotic pressure on either side of the semi-permeable membrane.
In the isotonic solution there will be free movement of only water molecules and not solutes.
isotonic solution is the solution when two solutions have equal solute concentration.
The concentration of the solution will be in equilibrium.
Evolution is the gradual process resulting in the changes in the genetic material of a population over generations. The mechanism that Darwin proposed for evolution is the process of natural selection. Natural selection is the key mechanism of evolution which increases the frequency of advantageous alleles in a population. Due to the limited resources in nature, organism with heritable traits favoring their survival and reproduction produce more offspring. It causes the population to become adapted to their environment and results in organisms with better survival ability and reproduction. These traits become heritable due to the reproductive advantage and are passed from the parents to the offspring. Over generations, the advantageous heritable trait becomes dominant in the population. It is responsible for the variation in the gene pool of the population which increases their fitness.
Ask a question. Question something that you want to experiment on. then, write a hypothesis. And it goes on from there.
