The scientific definition of evolution refers to changes in a species or population over time.
Evolution is a long-term process. It may take millions of years and several generation for an evolution to occur. The cause of evolution can be genetic as well as environmental. The evolution is a result of mutation. Evolution generally gives rise to new species, that is different from its ancestral population.
Population is a group of similar type of organisms. These organisms live in the same habitat, require same resources and have same kind of habits. The most essential criteria that defines a population is that the organisms of a population can mate with each other and produce offspring.

false not all scientists believe in evolution
Answer:
Chromatin helps regulate DNA replication.
Explanation:
Chromatin helps condense DNA strands to smaller units that can be easily managed during DNA replication and gene expression. This also prevents the breakage of the strands and facilitates equal distribution of chromosomes during cell division (during mitosis and meiosis).
<h2>Answer:</h2>
The pH of the pond water and survival rate of animal species living in the pond has a direct relationship with each other. Animal species can survive at a specific level of pH"Optimum pH" at which these species can show their maximum activity.
If we decrease the pH the pond water will become more acidic and it will become challenging for species to survive in the acidic environment and if we increase the pH the water becomes more alkaline and again it affects the marine life. So, the pH of pond water should be in normal ranges.
