Answer:
Lake A: pH = 4.5; Lake B: pH = 7.5
Explanation:
I think that one because if you look on the acid vs base chart acid is from 0-6 and bases are from 8-14 and acids are less toxic, so you would infer that lake A has acid and lake B has bases.
i would have picked the ones closest to 7 ,which is neutral, but I'm not sure that a base can be lower then 7 so I didn't pick answer C
A species is an integrated group of populations, integrated through their form, behavior, and preferred living conditions, the consequence of similar DNA and reproductive isolation from other species. A population is several organisms of the same kind in a particular area.
Examples of positive and beneficial mutation:
- Antibiotic resistance by bacteria
- Almond tree gene mutation
- Humans immunity to HIV
Examples of negative and harmful mutation
- Cystic fibrosis
- Frame shift mutation
- Cancer
Examples of neutral mutation;
- Bovine and human insulin
- Silent point mutation
- Missense mutation
<h3>What are mutation?</h3>
Mutations are results from change in gene structures that leads to variations in form that can be transferred or passed down to generations. This is usually caused by alterations in the single base unit of DNAs by insertion, deletion or rearrangement of genes or chromosomes.
Positive and beneficial mutations result in retained from of adaptation like antibiotic resistance by bacteria, harmful mutation causes harm such as cancer, while neutral has little or no effect example, silent mutations.
