The third one is the right answer.
Mutations appear randomly and these mutations can either have possitive, negative or neutral impact on the individual's survival. The environment of the individual amongst other factor determine the net effect of the mutation. For example:
A mutation on a shade plant for bigger leaves would have a possitive impact on the plants survival due to the increase of the photosynthetic tissue area. On the other hand the same mutation on a desert plant would have a negative impact on the plant's survival due to the increase of the leaf area which leads to increased water evaporation off the plant.
The answer is b because it will still fall as something else
Answer:
climate change
Explanation:
scientists are telling people what to do to save the planet
The bacteria Can Become Antibiotic resistant over time by adapting or evolving to them so new ones would have to be created to kill them. and this process just keeps repeating over and over.
Antibiotic resistance<span> is a consequence of evolution via natural selection. The</span>antibiotic<span> action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully </span>resistant<span> generation.</span>
