Answer:
does not change the identity of a substance
Explanation:
when a substance undergoes a physical change, the molecules move further apart but the chemical structure of the molecule does not change
Dissolving in water can conduct heat and electricity and rearranges atoms to form new substances but does not change the identity of a substance are some examples that describe physical changes.
What are physical changes?The changes can be physical and chemical. Physical changes occur when the physical properties changes. The changes can be of many types such as changes in colour, solubility, and change in the state of matter. Change of solid state to a liquid state, liquid state- to vapour and solid state -to vapour.
Neither the chemical nature nor the composition of the matter changes during the physical change. Rearrangement of the molecules takes place during the physical change without affecting the chemical composition of the matter.

what dose natural selection lead to
Hi!Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.
Answer:
Evolution
Explanation:
When natural selection occurs, more environmentally favorable traits are being passed on to offspring. As time goes by, more members of the population possess this trait until it's widespread amongst the species. This can even lead to speciation, the creation of a new species. This could also be the answer to your question. This process describes evolution, the process in which favorable and heritable traits are passed on throughout the generations and change the makeup of the species.

The most likely reason there are no colonies in cultures of this species at pH 4 and at pH 10 is that the species needs neutral pH to survive, not surviving at acidic or basic pH.
How are bacteria classified according to pH?Regarding pH tolerance, bacteria can be classified into three categories:
neutrophilsacidophilesand alkalinophiles.What is the neutral pH value?pH is the unit of measurement that describes this degree of acidity or alkalinity, measured on a scale of 0 to 14. Any pH below 7 is considered acidic and any pH above 7 is considered basic, or alkaline. A pH of 7 is neutral, which is neither acidic nor basic.
With this information, we can conclude that The most likely reason there are no colonies in cultures of this species at pH 4 and at pH 10 is that the species needs neutral pH to survive, not surviving at acidic or basic pH.
