Answer: You can add neutral solutions with a pH of 7, like water. Water will dissolve the alkaline/acidic pH to near 7 and 8, which are safe to drink.
Hope this helps you!
Sound would travel faster in a thick piece of metal since the molecules are closer together. However, since there are more molecules, it would be quieter on the other side than the hollow metal.
Answer:
the genotype of the parent guinea pigs are as follows:
RrBb (rough, black) and Rrbb (rough, white)
Explanation:
Since the phenotype of smooth coat is present in the offspring, the parent genotype cannot have RR alleles for their coat. Similarly, the rough, black parent cannot have BB alleles in its genotype because that will not yield a white coat color in its offspring.
After making the dihybdrid cross, the probability obtained for each phenotype is given below:
rough black: 
rough white: 
smooth black: 
smooth white: 
Hope that answers the question, have a great day!
