Adaptation is evolutionary process that fits organisms to their environment, increasing their evolutionary fitness. It is in a first place, a process rather then a part of a body or a physical form.
Adaptation is one of two main processes that explain the observed diversity of species. Other process is speciation.
All adaptations help organisms survive in their environments.
The adaptive traits may be physiological, behavioural or structural.
Many plants are able to propagate themselves using this method, the asexual reproduction. this method has two main types, which is the vegetative reproduction and the apomixis. vegetative reproduction results in new plants individual without the production of seeds or spores.
Answer: B. If the level of fecal coliform bacteria is low, then the water may still be unsafe because of the presence of other pathogens.
Explanation:
Fecal coliforms are anaerobic bacteria originating from the intestine of humans. They contaminate drinking water via poor sewage disposal or leaky sewage systems.
Scientists believe that fecal coliforms are not harmful, however they form a basis for the analysis of water quality because the presence of fecal coliforms in a water body is often an indication of the presence of some disease causing bacteria such as typhoid and dysentery causing microbes.
