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

What are two modes of genetic variation of organisms
Arada [10]

The genetic variation of organisms has three sources they are mutation, gene flow and sexual reproduction.

Explanation:

Genetic variation are caused by mutation , random mating, random fertilization and recombination between homologous chromosomes during meiosis.

It is a variation in alleles and genes, among the populations. There is a genetic variation within the family of closely- related individuals. If it is a neighborhood there are many families and there is also genetic variation among that group.

An exact genetic copy of the parent organism is produced in asexual reproduction. It only introduces the genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.
